Small purse of 6 coins of Sigismund III, Poland, silver, original, 17th century Sigismund III (Polish: Zygmunt III Waza, Sweden) Sigismund III (20 June 1566-30 April 1632) was King of Poland and Grand Duke of Lithuania from 27 December 1587, King of Sweden from 27 November 1592 to July 1599, grandson of Gustav Vasa and Sigismund the Old, son of King Johan III of Sweden and Catherine Jagiellonka, father of Władysław IV. Royal title in Latin since 1592: Sigismundus Tertius Dei gratia rex Poloniae, magnus dux Lithuaniae, Russiae, Prussiae, Masouiae, Samogitiae, Liuoniaeque etc. necnon Suecorum, Gothorum, Vandalorumque haeritari Russian translation: Sigismund the Third, by God's grace the King of Poland, Grand Duke of Lithuania, Russian, Prussian, Mazowiecki, Jmud, Livonian, etc. as well as the Crown King of Sweden, Goth and B Eneds. Having been elected to the throne of the Polish-Lithuanian Commonwealth, the Catholic Sigismund sought to unite under his rule the Polish-Lithuanian Commonwealth and Sweden. For a short time he succeeded. In 1592 he united both states under a personal union, but in 1595 the Swedish parliament elected his uncle, the Protestant Duke of S "dermanland, as regent of Sweden instead of the almost always absent Catholic king. Attempts to regain the Swedish throne Sigismund did not leave until his death. Sigismund remained a rather controversial figure in the history of the Polish-Lithuanian Commonwealth. On the one hand, his long reign fell to the highest point of the power of the Polish-Lithuanian state. On the other hand, it showed the first signs of decline, which in the future led to the death of the Polish-Lithuanian Commonwealth. Yeah.
