Partition Sejm
The Partition Sejm (Polish: Sejm Rozbiorowy) was a confederated session of the Polish-Lithuanian Commonwealth's parliament convened from April 19, 1773, to April 11, 1775, under intense pressure from the partitioning powers—Russia, Prussia, and Austria—to ratify the First Partition, which formalized the cession of substantial territories to these states.[1]
With Russian troops stationed in Warsaw and many deputies selected or influenced by foreign agents, the Sejm approved the partition treaties on September 30, 1773, legitimizing the loss of about 211,000 square kilometers of land—roughly 30% of the Commonwealth's territory—and over 4 million inhabitants, exceeding one-third of its population.[1][2][3]
This assembly, often criticized as a puppet body due to bribery, intimidation, and the suppression of the liberum veto through confederation, marked a pivotal step in the Commonwealth's dismemberment, sparking domestic outrage and opposition exemplified by figures like Tadeusz Rejtan, who dramatically protested the proceedings.[2][4]
Nevertheless, amid the capitulation, the Sejm achieved notable internal reforms, including the establishment of the Commission of National Education in October 1773, which reorganized the Jesuit educational system into Poland's first secular ministry of education and laid foundations for modern schooling.[2]
