"Sigismund II Augustus (Polish: Zygmunt II August, Lithuanian: Žygimantas Augustas; 1 August 1520 – 7 July 1572) was the King of Poland and Grand Duke of Lithuania, the son of Sigismund I the Old, whom Sigismund II succeeded in 1548.
Sigismund was the only legitimate son of Italian-born Bona Sforza and Sigismund the Old. From the beginning he was groomed and extensively educated as a successor. In 1529 he was crowned vivente rege while his father was still alive. Sigismund Augustus continued a tolerance policy towards minorities and maintained peaceful relations with neighbouring countries, with the exception of the Northern Seven Years´ War which aimed to secure Baltic trade. Under his patronage the culture flourished in Poland; he was a collector of tapestries from the Low Countries and collected military memorabilia as well as swords and armours. Sigismund Augustus´ rule is widely considered as the apex of the Polish Golden Age. In 1569 he oversaw the signing of the Union of Lublin between Poland and the Grand Duchy of Lithuania, which formed the Polish-Lithuanian Commonwealth and introduced an elective monarchy." - (en.wikipedia.org 31.01.2020)
