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]
