In 1941, Britain and Russia invaded Persia to put the Germans out. This happened during the 13th Majlis. Mohamed Reza Shah was the constitutional monarch from 1941-1953. From 1953 until the revolution of 1979, Shah was the absolute ruler. Elections for the 14th Majlis were in 1943. In 1950, a special assembly met to create a new upper house, or senate, with half of the members appointed by Shah. The assembly also gave Shah the power to dissolve the national assembly. The 21st Majlis was elected in September 1963.
