 Agricultural production was regulated by the "iqta", a Muslim system of land ownership and payments roughly (though far from exactly) equivalent to the feudal system of Europe, and this system was not heavily disrupted by the crusaders.As Hans Mayer says, "the Muslim inhabitants of the Latin Kingdom hardly ever appear in the Latin chronicles", so information on their role in society is difficult to find.The crusaders "had a natural tendency to ignore these matters as simply without interest and certainly not worthy of record."
