When was the Great Sejm of the Polish–Lithuanian Commonwealth established?
Sejm of the Polish–Lithuanian Commonwealth
Confederated sejm (Sejm skonfederowany) first appeared in 1573 (all convocation and election sejms were confederated), and became more popular in the 18th century as a counter to the disruption of liberum veto.[42] Seen as emergency or extraordinary sessions, they relied on majority voting to speed up the discussions and ensure a legislative outcome.[15][42] Many royal election sejms were confederated, as well as some of the normal sejm walny (general sejm) sessions.[38][42]
