Sigismund III Vasa Becomes King

Date: November 17, 1592 • Location: Rome, Italy

Sigismund III Vasa, who was already King of Poland, succeeded his father John III as King of Sweden.

Sigismund III Vasa was King of Poland and Grand Duke of Lithuania from 1587 to 1632 and, as Sigismund, King of Sweden from 1592 to 1599. He was the first Polish sovereign from the House of Vasa. Zealously religious, he imposed Catholicism across the vast realm, and his crusades against neighbouring states marked Poland's largest territorial expansion. A deeply polarising ruler, he presided over the end of the Golden Age of prosperity and achievement, further distinguished by the transfer of the country's capital from Kraków to Warsaw.
