Michael I (Polish: Michał Korybut Wiśniowiecki; Lithuanian: Mykolas I Kaributas Višnioveckis; 31 May 1640 – 10 November 1673) was the ruler of the Polish–Lithuanian Commonwealth as King of Poland and Grand Duke of Lithuania from 29 September 1669 until his death in 1673.
Michael was chosen partly because of the merit of his father, prince Jeremi Wiśniowiecki, a powerful border magnate who had helped suppress the rebellious Cossacks during the Khmelnytsky Uprising. After Michael's early death, these setbacks were reversed at the Battle of Khotyn in 1673 by his successor, John III Sobieski, who defeated an Austrian candidate in the election.
