The defeat of the Bar Confederation set the scene for the partition treaty of 5 August 1772, which was signed at Saint Petersburg by Russia, Prussia, and Austria. The treaty divested the Polish–Lithuanian Commonwealth of about a third of its territory and populationover and 4 million people. The three powers justified their annexation, citing anarchy in the Commonwealth and its refusal to cooperate with its neighbors' efforts to restore order. King Stanisław August yielded and on 19 April 1773, he called the Sejm into session. Only 102 of about 200 deputies attended what became known as the Partition Sejm. The rest were aware of the King's decision and refused. Despite protests from the deputy Tadeusz Rejtan and others, the treatylater known as the First Partition of Polandwas ratified.
