There were six major officers of the kingdom of Jerusalem: the constable, the marshal, the seneschal, the chamberlain (which were known as the "Grand Offices"), the butler and the chancellor. At certain times there were also bailiffs, viscounts and castellans.
Essentially these offices developed from the typical officials that existed in northern France in the 11th century, the homeland of the first kings of Jerusalem. The offices continued to develop in France and England, but in Jerusalem they tended to develop more slowly or not at all, taking on different roles than their European counterparts.
The lists given below are incomplete, as the specific names and dates of the officers are sometimes unknown. After the fall of the Kingdom of Jerusalem, the offices were sometimes awarded as honors by the kings of Cyprus and Jerusalem.
