Władysław IV Vasa (1595–1648)
Born 1595 CE, died 1648 CE.
Władysław IV Vasa or Ladislaus IV (9 June 1595 – 20 May 1648) was King of Poland, Grand Duke of Lithuania and claimant of the thrones of Sweden and Russia. Born into the House of Vasa as a prince of Poland and of Sweden, Władysław IV was the eldest son of Sigismund III Vasa and his first wife, Anna of Austria. Władysław was elected as the tsar of Russia by the Seven Boyars in 1610, when the Polish army captured Moscow, but did not assume the throne because of his father's position and a popular uprising. Nevertheless, until 1634, he used the titular title of grand duke of Moscow. Following his election as king of Poland and grand duke of Lithuania in 1632, he was largely successful in defending the Polish–Lithuanian Commonwealth against foreign invasion, most notably in the Smolensk War of 1632–1634 in which he participated personally. He supported religious tolerance and carried out military reforms, such as the founding of the Commonwealth Navy. Władysław was also a renowned patron of the arts and music.
