Grodno Sejm (Polish: Sejm grodzieński; Belarusian: Гарадзенскі сойм; Lithuanian: Gardino seimas) was the last Sejm (session of parliament) of the Polish–Lithuanian Commonwealth. The Grodno Sejm, held in fall of 1793 in Grodno, Grand Duchy of Lithuania (now Hrodna, Belarus) is infamous because its deputies, bribed or coerced by the Russian Empire, passed the act of Second Partition of Poland. The Sejm started on 17 June and ended on 23 November 1793. It ratified the division of the country in a futile attempt to prevent its subsequent complete annexation two years later in the 1795 Third Partition of Poland.
The Sejm was called to Grodno by the Russian Empire after the Polish–Russian War of 1792 ended with the victory of Russia and its allies, Targowica Confederation to confirm the Russian demands. Grodno was chosen for the Commonwealth's capital, as Warsaw was deemed too unsafe for Russians (and indeed it would prove so during the Warsaw Uprising next year). Many of the deputies were Russian supporters (like marshal of the Sejm, Stanisław Kostka Bieliński), with Russian representatives bribing some deputies and Russian armies forcing the election of their favoured candidate at local sejmiks. The Russians needed to use their army, as well as devote funds towards bribery, in order to bypass the opposition of Polish–Lithuanian deputies, as initially, the sejmiks refused to elect enough deputies to satisfy the requirements of a national Sejm.
