With Poland unable to defend itself effectively and foreign troops already inside the country, the Polish Sejm ratified the partition in 1773 during the Partition Sejm, which was convened by the three powers. On September 18, 1773, the committee signed the treaty of cession, renouncing all Commonwealth claims to the lost territories. In 1773 the annexed Prussian territories became the new province of West Prussia.
