a Polish prince from the Royal House of Vasa. He reigned as King of Poland and Grand Duke of Lithuania from 8 November 1632 to his death in 1648. In 1610 the teen-aged Wladyslaw was elected Tsar of Russia by the Seven Boyars, but did not assume the Russian throne due to his father's opposition and a popular uprising in Russia. Nevertheless, until 1634 he used the title of Grand Duke of Muscovy.
