Pope Pius VI, born Giovanni Angelo Braschi in 1717, served as the head of the Roman Catholic Church from 1775 until his death in 1799. He was known for his efforts to maintain the authority of the papacy during a time of political upheaval in Europe, particularly during the French Revolution. During his papacy, Pius VI faced significant challenges, including the loss of the Papal States and conflicts with revolutionary forces. He was eventually captured by the French and died in captivity in 1799. His reign is often remembered for its struggles against secularism and the changing political landscape of Europe.
