Possible end of the Late Modern period

There are differing approaches to defining a possible end or conclusion to the Late Modern period, or indeed whether it might be considered to have concluded at all; if that period is indeed concluded, then there are various options for how to label the subsequent era, i.e. the current contemporary era, as described below. * The

Some schools of thought hold that modernity ended in the late 20th century – in the 1980s or early 1990s – and that it was replaced by postmodernity, and still others would extend modernity to cover the developments denoted by postmodernity, while some believe that modernity ended sometime after World War II.

Firstly, the economy undergoes a transition from the production of goods to the provision of services; also, producing ideas is the main way to grow the economy. The term is used by various researchers and social scientists.


Possible subdivisions

Additionally, the Late Modern period can be divided into various smaller periods; there are differing opinions and approaches on which time periods to assert in doing so. *''Post-war era.'' This period refers mainly to social history and domestic economic activity, as it relates to societal progress and the major economic expansion after World War II which occurred in the United States and parts of the Western World. *'' Postcolonial Era.'' This relates to the major increase in decolonization which occurred directly as a result of World War II from 1946 onwards, as major European powers formally relinquished political control over almost all of their colonies and overseas possessions, leading to major new countries being formed with full sovereignty. * ''Cold War era.''

Mid-19th-century European revolts

The European Revolutions of 1848, known in some countries as the Spring of Nations or the Year of Revolution, were a series of political upheavals throughout the European continent. Described as a revolutionary wave, the period of unrest began in France and then, further propelled by the French Revolution of 1848, soon spread to the rest of Europe. Although most of the revolutions were quickly put down, there was a significant amount of violence in many areas, with tens of thousands of people tortured and killed. While the immediate political effects of the revolutions were reversed, the long-term reverberations of the events were far-reaching.

While some conflicts involved Spanish and Dutch forces, all pitted Great Britain, its colonies and American Indian allies on one side and France, its colonies and Indian allies on the other. The expanding French and British colonies were contending for control of the western, or interior, territories. Whenever the European countries went to war, there were actions within and by these colonies although the dates of the conflict did not necessarily exactly coincide with those of the larger conflicts.

Imperialism and empires

In the 1800s and early 1900s, once great and powerful Empires such as Spain, Ottoman Turkey, the Mughal Empire, and the Kingdom of Portugal began to break apart. Spain, which was at one time unrivaled in Europe, had been declining for a long time when it was crippled by Napoleon Bonaparte's invasion. Sensing the time was right, Spain's vast colonies in South America began a series of rebellions that ended with almost all of the Spanish territories gaining their independence. The once mighty Ottoman Empire was wracked with a series of revolutions, resulting with the Ottoman's only holding a small region that surrounded the capital, Istanbul. The Mughal empire, which was descended from the Mongol Khanate, was bested by the upcoming

African colonization

Following the abolition of the slave trade in 1807 and propelled by economic exploitation, the Scramble for Africa was initiated formally at the
Berlin West Africa Conference The Berlin Conference of 1884–1885, also known as the Congo Conference (, ) or West Africa Conference (, ), regulated European colonisation and trade in Africa during the New Imperialism period and coincided with Germany's sudden emergence ...
in 1884–1885. The Berlin Conference attempted to avoid war among the European powers by allowing the European rival countries to carve up the continent of Africa into national colonies. Africans were not consulted. The major European powers laid claim to the areas of Africa where they could exhibit a sphere of influence over the area. These claims did not have to have any substantial land holdings or treaties to be legitimate. The European power that demonstrated its control over a territory accepted the mandate to rule that region as a national colony. The European nation that held the claim developed and benefited from their colony's commercial interests without having to fear rival European competition. With the colonial claim came the underlying assumption that the European power that exerted control would use its mandate to offer protection and provide welfare for its colonial peoples, however, this principle remained more theory than practice. There were many documented instances of material and moral conditions deteriorating for native Africans in the late nineteenth and early twentieth centuries under European colonial rule, to the point where the colonial experience for them has been described as "hell on earth." At the time of the Berlin Conference, Africa contained one-fifth of the world's population living in one-quarter of the world's land area. However, from Europe's perspective, they were dividing an unknown continent. European countries established a few coastal colonies in Africa by the mid-nineteenth century, which included

(France), but until the late nineteenth century Europe largely traded with free African states without feeling the need for territorial possession. Until the 1880s most of Africa remained uncharted, with western maps from the period generally showing blank spaces for the continent's interior. From the 1880s to 1914, the European powers expanded their control across the African continent, competing with each other for Africa's land and resources. Great Britain controlled various colonial holdings in East Africa that spanned the length of the African continent from Egypt in the north to South Africa. The French gained major ground in West Africa, and the Portuguese held colonies in southern Africa. Germany, Italy, and Spain established a small number of colonies at various points throughout the continent, which included German East Africa (Tanganyika) and German Southwest Africa for Germany, Eritrea and Libya for Italy, and the Canary Islands and Rio de Oro in northwestern Africa for Spain. Finally, for King Leopold (ruled from 1865 to 1909), there was the large "piece of that great African cake" known as the Congo, which became his personal fiefdom. By 1914, almost the entire continent was under European control.

occurred during the reign of the Meiji Emperor. During this time, Japan started its modernization and rose to world power status. This era name means "Enlightened Rule". In Japan, the Meiji Restoration started in the 1860s, marking the rapid modernization by the Japanese themselves along European lines. Much research has focused on the issues of discontinuity versus continuity with the previous Tokugawa Period. It was not until the beginning of the Meiji Era that the Japanese government began taking modernization seriously. Japan expanded its military production base by opening arsenals in various locations. The hyobusho (war office) was replaced with a War Department and a Naval Department. The

class suffered great disappointment the following years. Laws were instituted that required every able-bodied male Japanese citizen, regardless of class, to serve a mandatory term of three years with the first reserves and two additional years with the second reserves. This action, the deathblow for the samurai warriors and their ''daimyōs'', initially met resistance from both the peasant and warrior alike. The peasant class interpreted the term for military service, ketsu-eki ("blood tax") literally, and attempted to avoid service by any means necessary. The Japanese government began modelling their ground forces after the French military. The French government contributed greatly to the training of Japanese officers. Many were employed at the military academy in Kyoto, and many more still were feverishly translating French field manuals for use in the Japanese ranks. Japan's modernized military gave Japan the opportunity to engage in Imperialism with its victory against the Qing Empire in the

Responding to these civil failures and discontent, the Qing Imperial Court did attempt to reform the government in various ways, as the decision to draft a constitution in 1906, the establishment of provincial legislatures in 1909, and the preparation for a national parliament in 1910. However, many of these measures were opposed by the conservatives of the Qing Court, and many reformers were either imprisoned or executed outright. The failures of the Imperial Court to enact such reforming measures of political liberalization and modernization caused the reformists to steer toward the road of revolution. The assertions of Chinese philosophy began to integrate concepts of Western philosophy, as steps toward modernization. By the time of the

On March 10, in Beijing, Shikai was sworn in as the second Provisional President of the Republic of China. After the early 20th century revolutions, shifting alliances of China's regional warlords waged war for control of the Beijing government. Despite the fact that various warlords gained control of the government in Beijing during the warlord era, this did not constitute a new era of control or governance, because other warlords did not acknowledge the transitory governments in this period and were a law unto themselves.

The 1920s and the Depression

The interwar period was the period between the end of the First World War and the beginning of the Second World War. This period was marked by turmoil in much of the world, as Europe struggled to recover from the devastation of the First World War.

The social and societal upheaval known as the Roaring Twenties began in North America and spread to Europe in the

International trade plunged by half to two-thirds, as did personal income, tax revenue, prices and profits. Cities all around the world were hit hard, especially those dependent on heavy industry. Construction was virtually halted in many countries. Farming and rural areas suffered as crop prices fell by roughly 60 percent. Facing plummeting demand with few alternate sources of jobs, areas dependent on primary sector industries suffered the most.

On December 7, 1941, Japan attacked the United States at Pearl Harbor, bringing it too into the war on the Allied side. China also joined the Allies, as eventually did most of the rest of the world. China was in turmoil at the time, and attacked Japanese armies through guerilla-type warfare. By the beginning of 1942, the major combatants were aligned as follows: the British Commonwealth, the United States, and the Soviet Union were fighting Germany and Italy; and the British Commonwealth, China, and the United States were fighting Japan.

Italy surrendered in September 1943 and was split into a northern Germany-occupied puppet state and an Allies-friendly state in the South; Germany surrendered in May 1945. Following the atomic bombings of Hiroshima and Nagasaki, Japan surrendered, marking the end of the war on September 2, 1945.

No country lost a greater portion of its population than Poland: approximately 5.6 million, or 16%, of its pre-war population of 34.8 million died. The Holocaust (which roughly means "burnt whole") was the deliberate and systematic murder of millions of Jews and other "unwanted" during World War II by the Nazi regime in Germany. Several differing views exist regarding whether it was intended to occur from the war's beginning, or if the plans for it came about later. Regardless, persecution of Jews extended well before the war even started, such as in the '' Kristallnacht'' (Night of Broken Glass). The Nazis used propaganda to great effect to stir up anti-Semitic feelings within ordinary Germans. After World War II, Europe was informally split into Western and Soviet spheres of influence.

The mid-20th century is distinguished from most of human history in that its most significant changes were directly or indirectly economic and technological in nature. Economic development was the force behind vast changes in everyday life, to a degree which was unprecedented in human history. Over the course of the 20th century, the world's per-capita gross domestic product grew by a factor of five, much more than all earlier centuries combined (including the 19th with its Industrial Revolution). Many economists make the case that this understates the magnitude of growth, as many of the goods and services consumed at the end of the 20th century, such as improved medicine (causing world life expectancy to increase by more than two decades) and communications technologies, were not available at any price at its beginning. However, the gulf between the world's rich and poor grew wider, and the majority of the global population remained in the poor side of the divide. Still, advancing technology and medicine has had a great impact even in the Global South. Large-scale industry and more centralized media made brutal dictatorships possible on an unprecedented scale in the middle of the century, leading to wars that were also unprecedented. However, the increased communications contributed to democratization. Technological developments included the development of airplanes and space exploration, nuclear technology, advancement in genetics, and the dawning of the

Pax Americana

Pax Americana is an appellation applied to the historical concept of relative liberal peace in the Western world, resulting from the preponderance of power enjoyed by the United States of America starting around the start of the 20th century. Although the term finds its primary utility in the latter half of the 20th century, it has been used in various places and eras. Its modern connotations concern the peace established after the end of World War II in 1945.

In other regions of the world, such as Latin America and Southeast Asia, the Soviet Union fostered communist revolutionary movements, which the United States and many of its allies opposed and, in some cases, attempted to "rollback, roll back".

(1979–1989) and Able Archer 83, NATO exercises in November 1983. There were also periods of reduced tension as both sides sought détente. Direct military attacks on adversaries were deterred by the potential for mutual assured destruction using deliverable nuclear weapons. The Cold War drew to a close in the late 1980s and the early 1990s. The United States under President Ronald Reagan increased diplomatic, military, and economic pressure on the Soviet Union, which was already suffering from Brezhnev stagnation, severe economic stagnation. In the second half of the 1980s, newly appointed Soviet leader Mikhail Gorbachev introduced the ''perestroika'' and ''glasnost'' reforms. History of the Soviet Union (1985–1991), The Soviet Union collapsed in 1991, leaving the United States as the dominant military power, though Russia retained much of the massive Soviet nuclear arsenal.


Latin America polarization

In Latin America in the 1970s, leftists acquired a significant political influence which prompted the right-wing, ecclesiastical authorities and a large portion of the individual country's upper class to support coups d'état to avoid what they perceived as a communist threat. This was further fueled by Cuban and United States intervention which led to a political polarization. Most South American countries were in some periods ruled by military dictatorships that were supported by the United States of America. In the 1970s, the regimes of the Southern Cone collaborated in Operation Condor killing many leftist dissidents, including some urban guerrillas. However, by the early 1990s all countries had restored their democracies.


Space Age

The Space Age is a period encompassing the activities related to the
Space Race The Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the t ...
, space exploration, space technology, and the cultural developments influenced by these events. The Space Age began with the development of several technologies that culminated with the launch of Sputnik 1 by the Soviet Union in October 1957. This was the world's first artificial satellite, orbiting the Earth in 98.1 minutes and weighing in at 83 kg. The launch of Sputnik 1 ushered a new era of political, scientific and technological achievements that became known as the Space Age. The Space Age was characterized by rapid development of new technology in a close race mostly between the United States and the Soviet Union. The Space Age brought the first human spaceflight during the Vostok programme and reached its peak with the Apollo program which captured the imagination of much of the world's population. The 1969 landing of Apollo 11 on the Moon was an event watched by over 500 million people around the world and is widely recognized as one of the defining moments of the 20th century. Since then, and with the end of the space race due to the

Information Age

The Information Age began in the mid-20th century, characterized by a rapid epochal shift from the traditional industry established by the Industrial Revolution to an economy primarily based upon information technology. The onset of the Information Age can be associated with the development of
