Said bin Taimur
Oil reserves in Dhofar were discovered in 1964 and extraction began in 1967. In the Dhofar Rebellion, which began in 1965, pro-Soviet forces were pitted against government troops. As the rebellion threatened the Sultan's control of Dhofar, Sultan Said bin Taimur was deposed in a bloodless coup (1970) by his son Qaboos bin Said, who expanded the Sultan of Oman's Armed Forces, modernised the state's administration and introduced social reforms. The uprising was finally put down in 1975 with the help of forces from Iran, Jordan, Pakistan and the British Royal Air Force, army and Special Air Service.
