(Redirected from Duchy of Parma and Piacenza)
The 'Duchy of Parma' was created in
1545 from that part of the
Duchy of Milan south of the
Po River, as a fief for
Pope Paul III's illegitimate son,
Pier Luigi Farnese, centered on the city of
Parma.
In
1556, the second Duke,
Ottavio Farnese, was given the city of
Piacenza, becoming thus also 'Duke of Piacenza', and so the state was thereafter properly known as the 'Duchies of Parma and Piacenza'.
The
Farnese family continued to rule until their extinction in
1731, at which point the duchy was inherited by the young son of the
King of Spain,
Don Charles, whose mother
Elizabeth Farnese was the Farnese heiress. He ruled until the end of the
War of the Polish Succession in
1735, when Parma was ceded to
Emperor Charles VI in exchange for the
Two Sicilies.
The
Habsburgs only ruled until the conclusion of the
Treaty of Aix-la-Chapelle in
1748, when it was ceded back to the
Bourbons in the person of
Don Philip, Don Charles's younger brother. As duke Philip, he became the founder of the
House of Bourbon-Parma.

The duchy of Parma and Piacenza (in red) in the context of late 18th century Italy.
In
1796, the duchy was occupied by French troops under
Napoleon Bonaparte. In the
Treaty of Aranjuez of
1801, duke Ferdinand formally agreed to cede the duchy to Napoleon. The territories were integrated into the
Cisalpine Republic until
1802, the
Italian Republic, from
1802 until
1805, and the
Kingdom of Italy, from
1805 until
1808, until in 1808
the French Empire annexed them and formed out of them the ''
Département'' of
Taro.
In
1814, the duchies were restored under Napoleon's Habsburg wife,
Marie Louise, who was to rule them for her lifetime. The duchy was renamed 'duchy of Parma, Piacenza and Guastalla', the name that it retained until the end.
After Marie Louise's death in
1847, the Duchy was restored to the Bourbon-Parma line, which had been ruling the tiny
duchy of Lucca. The Bourbons ruled until
1859, when they were driven out by a revolution following the Sardinian victory in their war against Austria.
The duchies of Parma, Piacenza and Guastalla and the duchy of Lucca joined with the
Grand Duchy of Tuscany and the
duchy of Modena to form the
United Provinces of Central Italy in December 1859, and were annexed to the
Kingdom of Sardinia in march of
1860.
The House of Bourbon continues to claim the title of duke of Parma to this day.
Carlos-Hugo (Carlist
pretender to the Spanish throne in the
1970s) has held the title since
1977.
