With the intensification of the Polish intervention in Muscovy, in 1609, the royal family moved to their residence in Vilnius, capital of the Grand Duchy of Lithuania. There he witnessed the fire of Vilnius, which required the royal family to evacuate their residence in the Vilnius Castle. Shortly afterwards, that year, Władysław, aged 15, was elected Tsar by Muscovy's aristocracy council of "Seven boyars", who overthrew tsar Vasily Shuysky during the Polish-Muscovite War and Muscovy's Time of Troubles. His election was ruined by his father, Sigismund, who aimed to convert Muscovy's population from Orthodox religion to Catholicism. Sigismund refused to agree to the boyar's request to send prince Władysław to Moscow and his conversion to Orthodoxy. Instead, Sigismund proposed that he should reign as a regent in Muscovy instead. This unrealistic proposal led to a resumption of hostilities. In 1611 and 1612, silver and gold coins (kopeks) were stuck in the Russian mints in Moscow and Novgorod with Władysław's titulary "Tsar and Grand Prince Vladislav Zigimontovych of all Russia".
