Rise to power;.

For six years prior to Saʿid ibn Taimur's overthrow, Qaboos was under virtual house arrest in the royal palace of Salalah. In July 1970, soldiers supporting Qaboos clashed with forces loyal to Sa'id ibn Taimur, and deposed him.[2] Qaboos maintains that his father abdicated the throne.[3] The British government helped to consolidate Qaboos' power. Qaboos acceded to the throne on 1970-07-23, moving to Muscat. There he declared that the country would no longer be known as Muscat and Oman, but would change its name to "the Sultanate of Oman" in order to better reflect its political unity.
The first pressing problem that Qaboos faced as Sultan was an armed communist insurgency from South Yemen, the Dhofar War (1965-1975). The Sultanate eventually defeated the incursion with help from British special forces and the Royal Air Force.
