It is estimated that between 1493 and 1793 sejms were held 240 times. Jędruch gives a higher number of 245, and notes that 192 of those were successfully completed, passing legislation. 32 sejms were vetoed with the infamous liberum veto, particularly in the first half of the 18th century. The last two sejms of the Commonwealth were the irregular four-year Great Sejm (1788–92), which passed the Constitution of the 3 May, and the infamous Grodno Sejm (1793) where deputies, bribed or coerced by the Russian Empire following the Commonwealth defeat in the War in Defense of the Constitution, annulled the short-lived Constitution and passed the act of Second Partition of Poland.
