How did the Dhofar rebellion end in 1975?

The Dhofar rebellion, which began in the mid-1960s as an uprising against the restrictive policies of Sultan Saʿīd ibn Taymūr, was finally crushed in December 1975.123

The conflict was brought to an end through a concerted military effort by the Sultan’s forces, which utilized British personnel and equipment, as well as support from Jordanian and Iranian troops. Financial assistance for these operations was provided by Saudi Arabia and the United Arab Emirates. By the time the rebellion was defeated, the Sultanate had significantly expanded its military capabilities, a process that began following the 1970 palace coup in which Qaboos bin Said overthrew his father and initiated a period of modernization and state consolidation.14
