Alessandro Farnese, the
Stato Pallavicino, an absolute monarchy feudal state in northwestern Emilia, encompassing the Marchesates of Busseto and Cortemaggiore, was annexed into the Duchy of Parma and Piacenza. This annexation expanded the duchy's territory and consolidated Farnese influence over the region. The Stato Pallavicino had been an autonomous entity under the
Pallavicino family since 1394, but its absorption marked the end of its independence. The
Farnese family continued to rule until the extinction of their male line in 1731.
The consolidation of the duchy
Ottavio Farnese strove to make the duchy prosperous, to win the benevolence of the people by applying the wise measures already taken by his father and to flatter the local nobility using more moderation than Pier Luigi, he knew how to consolidate the duchy by promoting its economy and financial and commercial exchanges and cultural, it started the territorial expansion with the annexation of some fiefdoms. In 1573 the number of inhabitants of the new capital had increased considerably reaching 26,000.

Alessandro died far from Parma on 3 December 1592 from gangrene caused by an arquebus ball during the Siege of Can de Bec, a year before his death he ordered the construction of the fortress of the Citadel with the aim of affirming the power of the family but also to provide work to a labor force of 2,500 people made up mostly of the poor sections of the city population. Ranuccio I, passionate about arts and music, made the ducal court the first in Italy in the musical arts. During this period, the city was enriched with unique monuments, such as the
Palazzo della Pilotta,
Palazzo Ducale and the
Teatro Farnese, modern legislation was passed, which made Parma a center of excellence both in terms of lifestyle and as an architectural model, elevating it as a cultural capital to the same level of other important European capitals. His government was guilty of the public execution of over 100 Parma citizens accused of conspiring against him. In 1628, on the death of Ranuccio I, the duchy was passed on to his just sixteen-year-old son

These were difficult years for the duchy, in addition to the terrible plague of 1630 which decimated the population, the new duke maintained an army of 6,000 infantry and to finance it he forced his subjects into severe deprivation, getting into debt with bankers and merchants. Despite the high expenses incurred, his first campaign was negative: Piacenza was occupied by the Spanish troops, his troops were defeated in Parma territory by

, and Odoardo was forced to sign a peace treaty with Spain under which, once the alliance with France was dissolved, he would have evacuated Piacenza.
On his death, which took place in Piacenza on 11 September 1646 at the age of 34, the duchy passed to his son
Ranuccio II and for two years the regency was ensured by his wife Margherita de' Medici and by his uncle the Cardinal
Francesco Maria Farnese, until the age of eighteen. In 1691 the Duchy of Parma was invaded by the
Imperial army and plundered by the four thousand soldiers who arrived in Parma with women and children; not only their maintenance fell on the subjects, but rape, abuse and violence followed one another without respite. Ranuccio II made many works to improve the situation of his subjects, but the contrast between the carefree life of the court and the coffers of the treasury was truly remarkable and to keep all the characters who rotated at the court of Parma, the duke was forced to tax everything, avoiding, however, touching the ecclesiastical income. During his reign, Ranuccio II bought precious paintings and volumes, he moved most of the works belonging to the
family collections preserved in the Roman residences to Parma and in 1688 the new Ducal Theater was inaugurated. Ranuccio II had a son destined to succeed him,

Three years before his death, thanks to the mediation of the ambassador Count Fabio Perletti, Odoardo had married
Countess Palatine Dorothea Sophie of Neuburg, with whom he had two children: Alessandro, who died at the age of eight months, and
Elisabeth. On 11 December 1694, upon the sudden death of Ranuccio II, the duchy then passed into the hands of the just sixteen-year-old second son

Rule of Francesco Farnese
Francesco Farnese's work fully brought the Farnese dynasty back to the center of great politics. Having inherited a disastrous financial situation, in order to try to heal it he cut all the unnecessary expenses of the court by firing most of the servants, musicians, jesters and dwarves. He also abolished performances, court parties and banquets. A hydraulic work was built to defend the city of Piacenza from the erosion of the Po, the expansion of the
University of Parma and the Collegio dei Nobili was favored, encouraging the study of public law, history, languages and geography. Artists, writers, musicians and playwrights enjoyed the protection of the Court. In 1712 the renovation works of the
Ducal Palace of Colorno began, completed in 1730. In 1714 the duchy achieved an important diplomatic success when Francesco, thanks to the offices of his ambassador in Spain
Giulio Alberoni, was able to marry his niece
Elisabeth to King
Philip V of Spain, who had been widowed earlier that year.
Extinction of the Farnese and House of Bourbon-Parma
Because of the lack of male heirs,
Elisabeth Farnese, niece of Duke
Antonio Farnese, was declared the Farnese heiress. She received many marriage proposals, finally marrying in 1714
Philip V of Spain. On the death of childless Duke Antonio in 1731, Philip V asserted the rights that his wife had over the duchies according to the agreements signed in the
Treaty of Vienna of 1725 and the
Treaty of Seville of 1729, and he claimed both for the Spanish

. The Bourbon-Parma regime was more reactionary than Marie-Louise's, provoking an uprising in 1848 which temporarily drove them out.
The Bourbons ruled until 1859, when they were driven out by a revolution following the French and Sardinian victory in the war against Austria (called the Austrian War in France and the
Second War of Independence in Italy). It was the only case in Italy where the ruling monarchs were successfully driven out by two consecutive uprisings, thanks to the inhabitants' rising aspirations for Italian unification and strong hatred for the Bourbons after the less reactionary reign of Marie Louise.
