The King-Crane commission consisted of a team of two Americans, Henry King and Charles Crane, who traveled to the Middle East and attempted to determine which mandatory power the indigenous people would prefer to rule over them. The commission showed that the Syrian Arabs' hierarchy of preferences were as follows: first independence, then rule by the Americans, then rule by the British and as a last choice rule by the French. However, neither the British nor the French had any intention of being influenced by the findings of the commission, and so the commission had little, if any effect. (Hughes, 1999, 1146-48).
