Overview

The two
Enlightenment philosophies of
liberalism
Liberalism is a Political philosophy, political and moral philosophy based on the Individual rights, rights of the individual, liberty, consent of the governed, political equality, the right to private property, and equality before the law. ...
and radicalism both shared the goal of liberating humanity from the remnants of feudalism. However, liberals regarded it as sufficient to establish individual rights that would protect the individual while radicals sought institutional, social/economic, and especially cultural/educational reform to allow every citizen to put those rights into practice. For this reason, radicalism went beyond the demand for liberty by seeking also equality, i.e. universality as in ''
Liberté, Égalité, Fraternité''.
In some countries, radicalism represented a minor wing within the Liberal political family, as in the case of England's

Britain possessed both trends: In England the Radicals were simply the
left wing of the Liberal coalition, though they often rebelled when the coalition's socially conservative
Whigs resisted democratic reforms, whereas in
Ireland Radicals lost faith in the ability of parliamentary gradualism to deliver egalitarian and democratic reform and, breaking away from the main body of liberals, pursued a radical-democratic parliamentary republic through separatism and insurrection. This does not mean that all radical parties were formed by left-wing liberals. In French political literature, it is normal to make a clear separation between Radicalism as a distinct political force to the left of Liberalism but to the right of Socialism. Over time, as new left-wing parties formed to address the new social issues, the right wing of the Radicals would splinter off in disagreement with the main Radical family and became absorbed as the left wing of the Liberal family—rather than the other way around, as in Britain and Belgium.
The distinction between Radicals and Liberals was made clear by the two mid-20th-century attempts to create an international for centrist democratic parties. In 1923–24, the French Radicals created an ''Entente Internationale des Partis Radicaux et des Partis Démocratiques similaires'': it was joined by the centre-left Radical parties of Europe, and in the democracies where no equivalent existed—Britain and Belgium—the liberal party was to allowed attend instead. After the Second World War the Radical International was not reformed; instead, a centre-right

was established, closer to the conservative-liberalism of the British and Belgian Liberal parties. This marked the end of Radicalism as an independent political force in Europe, though some countries such as France and Switzerland retained politically important Radical parties well into the 1950s–1960s. Many European parties that are nowadays categorised in the group of
social-liberal parties have a historical affinity with radicalism and may therefore be called "liberal-radical".

French republicans, such as universal male suffrage. In 1797, Fox declared for a "radical reform" of the

had fervently advocated and in March 1782 the King was forced to appoint an administration led by his opponents which sought to curb Royal patronage. In November 1783, he took his opportunity and used his influence in the House of Lords to defeat a Bill to reform the British East India Company, dismissed the government and appointed William Pitt the Younger as his Prime Minister. Pitt had previously called for Parliament to begin to reform itself, but he did not press for long for reforms the King did not like. Proposals Pitt made in April 1785 to redistribute seats from the "rotten boroughs" to London and the counties were defeated in the House of Commons by 248 votes to 174.
Popular agitation
In the wake of the French Revolution of 1789, Thomas Paine wrote ''The Rights of Man'' (1791) as a response to Edmund Burke's counterrevolutionary essay ''Reflections on the Revolution in France'' (1790), itself an attack on Richard Price's sermon that kicked off the so-called "pamphlet war" known as the Revolution Controversy. Mary Wollstonecraft, another supporter of Price, soon followed with ''A Vindication of the Rights of Woman''. They encouraged mass support for democratic reform along with rejection of the monarchy, aristocracy and all forms of privilege. Different strands of the movement developed, with middle class "reformers" aiming to widen the franchise to represent commercial and industrial interests and towns without parliamentary representation, while "Popular radicals" drawn from the middle class and from

s agitated to assert wider rights including relieving distress. The theoretical basis for electoral reform was provided by "Philosophical radicals" who followed the
utilitarian philosophy of
and strongly supported parliamentary reform, but were generally hostile to the arguments and tactics of the "popular radicals".
In Ireland, the Society of United Irishmen, United Irishmen movement took another direction, adding to the doctrine of a secular and parliamentary republic inspired by the American Revolution, American and French Revolution, French republican revolutions, another doctrine of the French Revolution:
civic nationalism. Dismayed by the inability of British parliamentarianism to introduce the root-and-branch democratic reforms desired, Irish Radicals channelled their movement into a republican form of nationalism that would provide equality as well as liberty. This was pursued through armed revolution and often with French assistance at Irish republicanism, various points over the late eighteenth and nineteenth centuries.
Popular Radicals were quick to go further than Paine, with Newcastle upon Tyne, Newcastle schoolmaster Thomas Spence demanding land nationalisation to redistribute wealth in a penny periodical he called ''Pig's Meat'' in a reference to Edmund Burke, Burke's phrase "swinish multitude". Radical organisations sprang up, such as the London Corresponding Society of artisans formed in January 1792 under the leadership of the shoemaker Thomas Hardy (political reformer), Thomas Hardy to call for the vote. One such was the Scotland, Scottish ''Society of the Friends of the People, Friends of the People'' society which in October 1793 held a British convention in Edinburgh with delegates from some of the English London Corresponding Society, corresponding societies. They issued a manifesto demanding universal male suffrage with annual elections and expressing their support for the principles of the French Revolution. The numbers involved in these movements were small and most wanted reform rather than revolution, but for the first time working men were organising for political change.
The government reacted harshly, imprisoning leading Scottish radicals, temporarily suspending habeas corpus in England and passing the Seditious Meetings Act 1795 which meant that a license was needed for any meeting in a public place consisting of fifty or more people. Throughout the Napoleonic Wars, the government took extensive stern measures against feared domestic unrest. The corresponding societies ended, but some radicals continued in secret, with Irish sympathisers in particular forming secret societies to overturn the government and encourage mutinies. In 1812,
Major John Cartwright formed the first Hampden Club, named after the
English Civil War

Writers like the radicals William Hone and Thomas Jonathan Wooler spread dissent with publications such as ''The Black Dwarf (journal), The Black Dwarf'' in defiance of a series of government acts to curb circulation of political literature. Radical riots in 1816 and 1817 were followed by the Peterloo massacre of 1819 publicised by Richard Carlile, who then continued to fight for press freedom from prison. The Six Acts of 1819 limited the right to demonstrate or hold public meetings. In

, agitation over three years culminated in an attempted general strike and abortive workers' uprising crushed by government troops in the "Radical War" of 1820. Magistrates powers were increased to crush demonstrations by manufacturers and action by radical Luddites.
To counter the established Church of England doctrine that the aristocratic social order was divinely ordained, radicals supported Jean-Baptiste Lamarck, Lamarckian Evolutionism, a theme proclaimed by street corner agitators as well as some established scientists such as Robert Edmund Grant.

and the House of Lords the Reform Act 1832 was put through with the support of public outcry, mass meetings of "political unions" and riots in some cities. This now enfranchised the middle classes, but failed to meet radical demands. The Whigs introduced reforming measures owing much to the ideas of the philosophic radicals, abolishing slavery and in 1834 introducing Thomas Malthus, Malthusian Poor Law Amendment Act 1834, Poor Law reforms which were bitterly opposed by "popular radicals" and writers like Thomas Carlyle. Following the 1832 Reform Act, the mainly aristocratic Whigs in the House of Commons were joined by a small number of
parliamentary Radicals as well as an increased number of middle class Whigs. By 1839, they were informally being called "the Liberal Party (UK), Liberal party".
Chartists

From 1836, working class Radicals unified around the Chartism, Chartist cause of electoral reform expressed in the ''People's Charter'' drawn up by six members of Parliament and six from the London Working Men's Association (associated with Owenite Utopian socialism), which called for six points: universal suffrage, equal-sized Election, electoral districts, secret ballot, an end to property qualification for Parliament, pay for Members of Parliament and Annual Parliaments. Chartists also expressed economic grievances, but their mass demonstrations and petitions to parliament were unsuccessful.
Despite initial disagreements, after their failure their cause was taken up by the middle class Anti-Corn Law League founded by Richard Cobden and John Bright in 1839 to oppose duties on imported grain which raised the price of food and so helped landowners at the expense of ordinary people.

by 1859. Demand for parliamentary reform increased by 1864 with agitation from John Bright and the Reform League.
When the Liberal government led by John Russell, 1st Earl Russell, Lord Russell and William Ewart Gladstone introduced a modest bill for parliamentary reform, it was defeated by both Tories and reform Liberals, forcing the government to resign. The Tories under Edward Smith-Stanley, 14th Earl of Derby, Lord Derby and Benjamin Disraeli took office and the new government decided to "dish the Whigs" and "take a leap in the dark" to take the credit for the reform. As a minority government, they had to accept radical amendments and Disraeli's Reform Act 1867 almost doubled the electorate, giving the vote even to working men.
The Radicals, having been strenuous in their efforts on behalf of the working classes, earned a deeply loyal following—British trade unionists from 1874 until 1892, upon being elected to Parliament, never considered themselves to be anything other than Radicals and were labeled Liberal-Labour (UK), Lib-Lab candidates. Radical trade unionists formed the basis for what later became the Labour Party (UK), Labour Party.
Belgium
The territories of modern Belgium had been merged into the Kingdom of the Netherlands in 1815. Aside from various religious and socioeconomic tensions between the Dutch north and proto-Belgian south, over the 1820s a young generation of Belgians, heavily influenced by French Enlightenment ideas, had formulated criticisms of the Dutch monarchy as autocratic. The monarch enjoyed broad personal powers, his ministers were irresponsible before parliament; the separation of powers was minimal; freedom of press and association were limited; the principle of universal suffrage was undermined by the fact that the largely Catholic south, despite possessing two-thirds of the population, received as many seats to the Estates-General (parliament) as the smaller Protestant north; and the Dutch authorities were suspected of forcing Protestantism onto Catholics. These concerns combined to produce a pro-Catholic Radicalism distinct from both the anticlerical Radicalism of France, and the Protestant Liberalism of the Dutch north.
Following the political crisis of 1829, where the Crown Prince was named prime minister, a limited reform was introduced establishing constitutional rights, similar to the charter of rights of France's autocratic Restoration Monarchy; the Belgian Radicals, like their French counterparts, regarded such a charter of rights as insufficient, potentially revocable by a whim of the monarch. Belgian Radicals closely followed the situation in France when, on 26 July to 1 August 1830, a conservative-liberal July Revolution, revolution broke out, overthrowing the autocratic monarchy for a July Monarchy, liberal constitutional monarchy. Within a month a revolt had erupted in Brussels before spreading to the rest of the Belgian provinces. After Belgian independence, the Constitution of 1831 established a constitutional monarchy and parliamentary regime, and provided a list of fundamental civil rights inspired by the French Declaration of the Right of Man.
As in Britain, Radicals in Belgium continued to operate within the Liberal Party, campaigning throughout the 19th Century for the property-restricted suffrage to be extended. This was extended a first time in 1883, and universal male suffrage was achieved in 1893 (though female suffrage would have to wait until 1919). After this Radicalism was a minor political force in Belgium, its role taken over by the emergence of a powerful Belgian Labour Party, social-democratic party.
France

During the nineteenth century, the Radicals in France were the political group of the far-left, relative to the centre-left "Opportunist Republicans, opportunists" (Gambetta: conservative-liberal and republican), the centre-right

openly. Some republicans reconciled themselves to pursuing liberalism through the socially-conservative monarchy—the 'opportunists'. Those who remained intransigent in believing that the French Revolution needed to be completed through a republican regime based on parliamentary democracy and universal suffrage therefore tended to call themselves "Radicals" – a term meaning 'Purists'.
Under the Second Republic (1848–1852), the Radicals, on a platform of seeking a "social and democratic republic", sat together in parliament in a group named The Mountain (1849), The Mountain. When Napoleon III, Louis-Napoléon Bonaparte launched his French coup d'état of 1851, military coup, Radicals across France rose up in insurrection to defend the democratic republic. This experience would mark French Radicalism for the next century, prompting permanent vigilance against all those who – from Patrice de MacMahon, Duke of Magenta, Marshall Mac-Mahon to Charles de Gaulle, General De Gaulle – were suspected of seeking to overthrow the constitutional, parliamentary regime.
After the return to parliamentary democracy in 1871, the Radicals emerged as a significant political force: led by Georges Clemenceau, they claimed that the socially-conservative liberal republicanism of Léon Gambetta and Jules Ferry had drifted away from the ideals of the French Revolution, and that the Radicals were the true heirs to 1791. In 1881, they put forward their programme of broad social reforms: from then on, the tactic of the main Radical Party was to have 'no enemies to the left' of the Republic, allying with any group that sought social reform while accepting the legality of the parliamentary republic.

The Radicals were not yet a political party as they sat together in parliament out of kinship, but they possessed minimal organisation outside of parliament. The first half of the Third Republic saw several events that caused them to fear a far-right takeover of parliament that might end democracy, as Louis-Napoléon had: Patrice de Mac-Mahon, Marshall Mac-Mahon's self-coup in 1876, the Boulangism, General Boulanger crisis in the 1880s, the Dreyfus Affair in the 1890s. The Radicals were swept to power first in a Pierre Waldeck-Rousseau, coalition government (1899) then in Émile Combes, governments of their own from 1902. They finally managed to implement their long-standing programme of reforms, such as the Secularism in France, separation of Church and State, or the introduction of secret ballotting. In order to ensure that their legacy would remain unreversed, they unified the local Radical committees into an elector party: the Radical Party (France), Radical-Socialist Party, the first major modern political party in French history.
Intellectuals played a powerful role. A major spokesman of radicalism was Émile Chartier (1868–1951), who wrote under the pseudonym "Alain." He was a leading theorist of radicalism, and his influence extended through the Third and Fourth Republics. He stressed individualism, seeking to defend the citizen against the state. He warned against all forms of power – military, clerical, and economic. To oppose them he exalted the small farmer, the small shopkeeper, the small town, and the little man. He idealized country life and saw Paris as a dangerous font of power.
The Radical–Socialist Party was the main governmental party of the French Third Republic, Third Republic between 1901 and 1919, and dominated government again between 1924 and 1926, 1932–1933 and 1937–1940; the centre-right governments dominated by the conservative-liberal centre-right often gave a portfolio to a Radical, who would join cabinet in a personal capacity as the most left-leaning minister.
The party itself was discredited after 1940, due to fact that many (though not all) of its parliamentarians had voted to establish the Vichy France, Vichy regime. Under the dictatorship several prominent Radicals, such as the young left-leaning former education minister Jean Zay, and the influential editorialist Maurice Sarraut (brother to the more famous Radical party leader Albert Sarraut, Albert), were assassinated by Milice, the regime's paramilitary police, while others, notably Jean Moulin, participated in the French Resistance, resistance movement to French Fourth Republic, restore the Republic.

to combine the politics of French Radicalism with credibility derived from members' activism in the French resistance.
In the 1950s, Pierre Mendès-France attempted to rebuild the Radical Party as an alternative to both the Christian-democratic People's Republican Movement, MRP, while also leading the opposition to Gaullism which he feared to be another attempt at a right-wing coup. During this period the Radicals frequently governed as part of a Third Force (France), coalition of centrist parties, spanning from the Socialists to the Christian-democrats.
Ultimately the installation of the French Fifth Republic, Fifth Republic in 1958, and the subsequent emergence of a two-party system based on the Socialist and Gaullist movements, destroyed the niche for an autonomous Radical party. The Radical Party split into various tendencies. Its leading personality, Mendès-France himself, left in 1961 in protest at the party's acceptance of De Gaulle's military coup and joined the small social-democratic Unified Socialist Party (France), Unified Socialist Party. A decade later, a second faction advocated maintaining an alliance with the Socialist-dominated coalition of the left; it broke away in 1972 to form the

, which maintains close ties to the Socialist Party. The remainder of the original Radical Party became a de facto liberal-conservative party of the centre-right: renamed as the Radical Party (France), 'Valoisien' Radical Party, it advocated alliances with the rest of the liberal centre-right, participating first in the pro-Giscard d'Estaing Union for French Democracy (1972), then with the Conservatism, conservative Union for a Popular Movement (2002).
Ireland

Irish republicanism was influenced by American and French radicalism. Typical of these classical Radicals are 19th century such as the United Irishmen in the 1790s, Young Irelanders in the 1840s, Fenian Brotherhood in the 1880s, as well as Sinn Féin, and Fianna Fáil in the 1920s.

Japan's radical-liberalism during the Empire of Japan was dissident because it resisted the government's political oppression of republicanism. Rikken Minseitō, who supported the Empire of Japan's system at the time, were classified as "Conservative liberalism, conservative".

In German-speaking countries, this current is known as :de:Freisinn, Freisinn (literally "free mind", or "freethought"), as in German Freeminded Party from 1884 to 1893, then Eugen Richter's Freeminded People's Party (Germany), Freeminded People's Party; and the Free Democratic Party of Switzerland.
The Freethinker parties, located mainly in the Netherlands, Scandinavia and German-speaking countries, included:
* In Switzerland:
** The Radical movement (or "Free-thinking" movement in the German-speaking cantons), not yet a political party, emerged during the period of Restoration and Regeneration in Switzerland, Regeneration, starting 1830 (coincident with the French July Revolution). It became the dominant political force under the Swiss Federal Constitution, 1848 Constitution, holding all seven posts in the Federal Council until 1891.
** The Radical Democratic Party of Switzerland, Radical-Democratic Party (PRD; in French-speaking Switzerland), also known as the Free-minded Democratic Party (FDP; in German-speaking Switzerland) existed from 1894 to 2009. It started as a centre-left party but gradually moved to the centre-right in the course of time. It was still by far the strongest party until the 1940s, holding at least four of seven posts in the Federal Council. Under the 1959 "magic formula" it held two of seven posts in the Federal Council.
** The Radical Liberal Party of Switzerland, Radical-Liberal Party (PLR), or ''FDP. The Liberals'' (in the German-speaking regions), was formed in 2009 by the merger of PRD/FDP with the smaller, more right-leaning Liberal Party of Switzerland.
* In the Netherlands:
**
Radical League (1882–1901)
** Free-thinking Democratic League, Free-minded Democratic League, a political party in the Netherlands from 1901 to 1946
* In Germany, a succession of Radical parties existed:
** The German Free-minded Party (1884–1893), which split into two successors:
** The left-leaning Free-minded People's Party (Germany), Free-minded People's Party (1893–1910)
** The centre-leaning Free-minded Union (1893–1910)
** These merged as the
Progressive People's Party (1910–1918)
** This was reformed as the
German Democratic Party (DDP; 1918–1930)
** The Radical Democratic Party formed by left-leaning and pacifist members of the DDP (1930–1933)
* In Austria, liberalism was originally closely related to German nationalism but later split:
**liberal-nationalist Progressive Club (1873–1881).
**United Left (1881–1888).
**United German Left (1888–1897)
**German Progressive Party (1896–1910).
**Centrist Democrats, Democratic Middle-class Party, Democratic Economic Party and Economic People's Party (c. 1919)
**Civic Workers' Party (1920–1927)
**Democratic List (1927)
*Branches of German and Austrian formed new parties in aftermath of World War I
**Territory of the Saar Basin:
***German Democratic Party of the Territory of the Saar Basin (1922–1924; 1928–1935)
**Free City of Danzig:
***German Democratic Party (1920–1925)
***German Party for Progress and the Economy (1921–1925)
***German Liberal Party (1925–1932)
**Czechoslovakia:
***German Liberal Party (1919–1938)
* In Denmark:
** The current Liberal Party began as a radical party in 1870, hence its name in Danish (, meaning 'Left'). When it became more conservative, the Radical wing split in 1905 to form a new party, known as
Radikale Venstre ('Radical Left').
* In Norway:
** The current Liberal Party began as a radical party in 1884, hence its name in Norwegian (Liberal Party (Norway), Venstre, meaning 'Left').
In Mediterranean Europe, Radical parties were often labelled 'Democratic' or 'Republican' parties:
* In France, during the nineteenth and the first half of the twentieth century, radicalism was intertwined with republicanism to the point that radical parties were often simply labelled 'republicans'. The election of Alexandre Auguste Ledru-Rollin, Alexandre Ledru-Rollin in 1841 is generally considered the start of the radical-republican movement as a political force in France. Over the next century a pattern emerged of Radicals forming a party on the left of the parliamentary spectrum (but to the right of socialists), only for the party to drift to the centre, which would cause the party's left to splinter off and re-establish a new main Radical party while the weakened parent party was eventually absorbed by the liberal centre. This meant that there were generally two rival Radical parties at any one time, one leaning relatively towards socialism, and the other relatively towards liberalism.
** The Mountain (1849), La Montagne (The Mountain) (1848–1851) was the first parliamentary group to provide a home for France's miscellaneous radical republicans. Its official name, the Socialist Democrat group, signalled its two tendencies: the more socialist-leaning tendency of Louis Blanc, and the more middle-class democratic-reformist tendency of Alexandre Auguste Ledru-Rollin, Alexandre Ledru-Rollin. At that time it represented a very small political current situated on the far-left of the parliamentary spectrum.
** The Republican Union (France), Republican Union (1871–1884), led by Léon Gambetta, was the Mountain's spiritual successor during the transition to democracy; its members included former parliamentarians of the Montagne such as Louis Blanc, and prominent Radical intellectuals like Victor Hugo. A minor force at first, by 1876 it had grown in parliamentary strength but begun to drift towards centrist cooperation with liberal Catholics; this prompted the party's more fervent radicals to splinter off in several waves and form new Radical parties (Georges Clemenceau in 1876; René Goblet's Radical Left in 1881; Isambart's Progressive Union in 1894).
** The ''Progressive Union'' (1894–1902) was originally a splinter of the Republican Union by left-leaning radicals during the Dreyfus Affair. In 1902 the formation of the major new Radical-Socialist Party to its immediate left forced it to pick a political family, and it chose to ally then merge with other centrist parties to form the politically liberal Republican Democratic Alliance.
** Radical Left (France), Radical Left (1881–1940), a parliamentary group initially formed by hardline anticlerical radicals dissatisfied with the Republican Union's centrism. It was a major political force in centre-left and centrist governments between 1898 and 1918, and regularly provided ministers in centrist and right-wing governments between 1918 and 1940; the importance of this current was underlined by its leader, the veteran Radical Georges Clemenceau, being called to lead the Sacred Union, war government during the First World War. The foundation of the PRRRS to its left in 1901 pushed it one space towards the centre and it increasingly drifted into alliance with the Democratic Alliance (France), liberal republican centre-right. By 1918 it was de facto a party of the centre-right, and from 1936 was essentially absorbed by the liberal right, its old political niche taken over by the PRRRS.
** The ''Radical Party (France), Radical-Socialist Party'' (officially the ''Radical, Republican and Radical-Socialist Party'' or ''PRRRS''), the most famous of France's many radical parties. It was the dominant political force in France from 1901 to 1919, and a major force from 1920 to 1940. Due to its central political role it could alternate in and out of alliance with both socialists and with conservative-liberals; this prompted several splinters by the party's most left- and right-wing members:
** Centrist and centre-right Radical splinters: The ''Social and Unionist Radical Party'' (1928–37) was a small splinter of anti-socialist radicals from the PRRRS, led by Henry Franklin-Bouillon, who preferred to ally with the centrist Radical Left and other liberal right wing parties. The ''French Radical Party'' (1937–1938) was a similar small anti-communist splinter, led by André Grisoni. These two small groups merged in 1938 as the short-lived ''Independent'' ''Radical Party,'' which was itself restored after the Second World War and was a founding organisation of the ''Alliance of Left Republicans.''
** ''Independent Radical Party'' (1937–1940), a merger of the ''Unionist Radical Party'' and the ''French Radical Party''.
** Social-democratic Radical splinters: The ''Republican-Socialist Party'' (1911–1935) and the ''French Socialist Party'' (1923–1935) were two small parties formed of left-wing Radicals philosophically close to social-democracy or rightwing social-democrats philosophically close to Radicalism, but unable or unwilling to join either the French Section of the Workers' International, official socialist party or the PRRRS. Although electorally small, they were a significant political force as they regularly provided ministers and heads of government in left-wing and centrist coalitions. They merged with other social-democratic parties and independents in 1935 as the Socialist Republican Union.
** The ''Camille Pelletain Radical Party'', a small splinter of anti-fascists from the PRRRS that briefly existed between 1934 and 1936. The party opposed the willingness by the PRRRS's party leaders during 1934–35 to prefer cooperation with the right and far-right rather than with other left-wing parties. Its name was a reference to a leading historical figure of left-wing Radicalism, Camille Pelletan, Camile Pelletain, as a way to lay claim to an authentic Radical tradition felt to have been abandoned by the official party. Once the PRRRS returned to allying with the rest of the left in 1936, the Pelletanist Radicals returned to the old party.
** After the Second World War, the pre-war Radical-Socialist Party, Radical Left party and their smaller counterparts were left discredited and weakened as Communism in France, communism, French Section of the Workers' International, social-democracy, Popular Republican Movement, Christian-democracy and Gaullism exploded in popularity. The remaining Radicals mostly banded together with the remnants of other pre-war liberal parties to form a centre-right umbrella party named the Rally of Republican Lefts, Rally of the Republican Left: this was no longer distinctly Radical in ideology, but espoused

* In Spain, Radicalism took the form of various 'democratic', 'progressive', 'republican' and 'radical' parties.
** The Progressive Party (Spain), Progressive Party (1835–1869), formed by former participants in the radical Revolution of 1820;
** The Democratic Party (Spain), Democratic Party (1849–1869), split from the Progressive Party, a progressive party of Jacobin inspiration, mainly active in the 1850s. It split into two successor parties:

** The Radical Democratic Party (Spain), Radical Democratic Party (or just "Radical Party") (1869/71–1876), whose leader Manuel Ruiz Zorrilla was Prime Minister for two short periods in 1871 and 1872–1873; later known as the ''Republican Reformist Party'' (1876–1880). It was refounded as the Progressive Republican Party (Spain), Progressive Republican Party (1880–1912), whose majority merged into the Republican Union Party (Spain), Republican Union Party (1903–1910)

Serbia and Montenegro
Radicalism had played a pivotal role in the birth and development of parliamentarism and the construction of the modern Serbian state leading to the Yugoslavian unification. The
People's Radical Party formed in 1881 was the strongest political party and was in power in the Kingdom of Serbia more than all others together. The 1888 Constitution of the Kingdom of Serbia that defined it as an independent nation and formalised parliamentary democracy was among the most advanced in the entire world due to Radical contribution and it is known as ''The Radical Constitution''. In 1902, a crack had occurred in which the Independent Radical Party left and "the Olde" remained in the party, leading the original People's Radical Party to stray far from progressivism and into right-wing nationalism and conservatism. In the Kingdom of Yugoslavia, the Independent Radicals united with the rest of the Serbian opposition and the liberal and civic groups in the rest of the new country, forming the Democratic Party (Yugoslavia), Yugoslav Democratic Party, while several Republican dissidents formed a Republican Party. The NRS had promoted Serb nationalism and put itself as the defender of Serb national interests. Democrats and Radicals were the dominant political parties, especially since the exclusion of the Communists. Later far-right parties such as the Yugoslav Radical Union and the Serbian Radical Party adopted the title "radical" as allusion to NRS.
In Montenegro, a People's Party (Montenegro, 1906), People's Party was formed in 1907 as the country's first political party and remained the largest in the period of country's parliamentary history until the Yugoslavian unification. Later, a True People's Party was formed, which never got widespread popular support and whose bigger part had joined the original NS, but the difference was not ideological and instead was opposition and support of the Crown and sometimes in foreign relations to Serbia (the clubbists were the crown's dissidents and supporters of the people as well as Serbia as a regional power and brotherly ally—the rightists were generally anti-democratic and autocratic monarchist and also distrustful to the Serbian government's acts on the national plan).
