Władysław IV Vasa
Władysław IV Vasa or Ladislaus IV Vasa (9 June 1595 – 20 May 1648) was king of Poland, of the House of Vasa, who ruled from 1632 until his death in 1648.
Władysław IV was the son of Sigismund III Vasa (Polish: "Zygmunt III Waza") and his wife, Anna of Austria (also known as Anna of Habsburg).
Władysław was elected Tsar of Russia by the Seven Boyars in 1610 when the Polish army captured Moscow, but did not assume the throne due to his father's position and a popular uprising.
Nevertheless, until 1634 he used the title of Grand Duke of Muscovy.
Elected king of Poland in 1632, he was fairly successful in defending the Polish–Lithuanian Commonwealth against invasion, most notably in the Smolensk War of 1632–34, in which he participated personally.
He supported religious tolerance and carried out military reforms, such as the founding of the Commonwealth Navy.
He was also a renowned patron of the arts and music.
He failed, however, to realize his dreams of regaining the Swedish crown, gaining fame by defeating the Ottoman Empire, strengthening royal power, and reforming the Commonwealth.
He died without a legitimate male heir and was succeeded to the Polish throne by his half-brother, John II Casimir Vasa ("Jan Kazimierz Waza").
Władysław's death marked the end of relative stability in the Polish–Lithuanian Commonwealth, as conflicts and tensions that had been growing over several decades came to a head with devastating consequences, notably the largest of the Cossack uprisings – the Khmelnytsky Uprising (1648) – and the Swedish invasion ("the Deluge", 1655–60).
