King Talal bin Abdullah assumed the throne shortly after themartyrdom of King Abdullah on July 20, 1951. However, and due to healthreasons, he abdicated the throne less than a year later, on August 11, 1952, infavor of his eldest son Hussein, the heir apparent. During his tenure, KingTalal did much to further the previously strained relations between Jordan andSaudi Arabia and Egypt. He was also largely responsible for the development ofa new, liberalized constitution. This document made the governmentcollectively, and the ministers individually, responsible before parliament andwas ratified on January 1, 1952. The smoothness with which the reins of powerwere transferred through Abdullah, Talal and Hussein was remarkable, indicatingthe extent to which King Abdullah had succeeded in putting the Jordanianmonarchy in constitutional order.
