From August 25 to September 17, 1941, Great Britain and the Soviet Union carried out a joint invasion of Iran. This invasion was intended to secure and defend the Allied supply lines through the area along with overthrowing of king of Persia, Rezā Shāh, who was suspected of sympathizing with the Axis. Rezā Shāh refused to deploy British and Soviet troops at their request, violating the agreement between the Soviets and Iranians in 1921. According to the agreement, the USSR had a right to deploy its troops in Iranian territory in the case of threats to its southern borders.
