Peter von Biron

Life and reign

Peter was born in Jelgava (German: Mitau) as the only son of Ernst Johann von Biron, future Duke of Courland, and his wife Benigna von Trotha. From 1730 until 1740, he and his family lived in Moscow and St. Petersburg, where his father was a lover and favorite of Anna of Russia.

When he was 16 years old, he was forced to follow his family into their Siberian exile, first to Tobolsk Governorate, then from 1742 until 1762 in Yaroslavj. In 1765, he married Princess Caroline of Waldeck and Pyrmont, but the union produced only one son, who was stillborn in 1766.

In 1769, he was given the Duchy of Courland and Semigallia by his father. However, he had acted as de facto duke for several years already. In 1770, he gave an oath to the Courland Knighthood. He was also elected a Fellow of the Royal Society in 1771.

In 1775, he founded the Academia Petrina in Jelgava. Hoping that the school would grow into a university, he addressed Immanuel Kant and Johann Gottfried Herder to become professors, but both refused.

In 1774, he married Yevdokiya Yusupova, but the marriage was unsuccesfull and they divorced in 1778. In 1779, he married Dorothea von Medem, a marriage that produced 6 children.

He ceded the government of the duchy and then its territory to the Russian Empire in 1795, and received in return a high appanage. This helped him to buy and refurbish for his purposes a palace in Berlin's street of Unter den Linden (Palais Kurland, bought in 1782). In 1785, he bought the park and palace in Friedrichsfelde (part of today's Tierpark Berlin), which he rebuilt in luxurious beauty.

In April 1786, he purchased the Duchy of Sagan from the Bohemian Lobkovic family, then additionally used the title of Duke of Żagań. In 1795, Russia determined the further fate of Courland when, with its allies, it began the third division of Poland. Given a "nice recommendation" by Russia, Duke Peter von Biron gave up his rights to Russia. With the signing of the final document on 28 March 1795, the Duchy of Courland ceased to exist.

Five years later, after several months of illness, Peter died in Gellenau. First, he was buried in an Augustinian abbey church, but in 1847, he was reburied in a Lutheran church in Żagań.
