The court developed gradually during the early 12th century CE, along with the kingdom itself, in the aftermath of the First Crusade. Technically all vassals of the king which were subject to its decisions had the right to sit and vote, but in practice only the more wealthy nobles did so; certain nobles attended regularly and tended to serve as presiding judges when necessary. This developed into a system of higher nobles (direct vassals of the king) and lesser nobles (indirect vassals, who owed service to the higher nobles), with different privileges depending on idiosyncratic circumstances. Anyone who had committed perjury or had broken an oath (whether a higher or lesser noble) forfeited his right to speak and vote. Only four votes (the king and any three vassals) were required to form a quorum.
