Abstract: In the Kingdom of Jerusalem, from 1099 to 1291, political action had a collective dimension in addition to what was performed by royalty or to compensate for the absence of a king. The jurists of the thirteenth century offered a model reducing this group, which formed an active political elite, to something merely feudal. This paper considers how to determine the changes occurring in the composition and the modalities of the action of this elite, noting a significant beginning and a very context-dependent revival.
