 In 1644 , after the false news of the death of Adam <unk> , Wiśniowiecki took over his disputed estate of <unk> by <unk> . For this he was at first sentenced to exile , but due to his influence , even the King could not realistically expect to enforce this ruling without a civil war . Eventually after more discussions at local <unk> and then in the Sejm , he won the case and was granted the right for <unk> . In 1646 , after the death of Koniecpolski , he became the voivode of Ruthenia . He invaded and took over the town of <unk> which was also being claimed by a son of Koniecpolski , Aleksander Koniecpolski , but a year later , in 1647 , he lost that case and was forced to return the town .
