Said bin Taimur
During the second half of the 19th century, the fortunes of the Al Bu Sa`id declined and friction with the Imams of the interior resurfaced. Muscat and Muttrah were attacked by tribes from the interior in 1895 and again in 1915. A tentative ceasefire was brokered by the British, which gave the interior more autonomy. However, conflicts among the disparate tribes of the interior, and with the Sultan of Muscat and Oman continued into the 1950s, and eventually escalated into the Dhofar Rebellion (1962). The rebellion forced the Sultan Said bin Taimur to seek the assistance of the British in quelling the uprisings from the interior. The failed assassination attempt of April 26, 1966 on Said bin Taimur led to the further isolation of the Sultan, who had moved his residence from Muscat to Salalah, amidst the civilian armed conflict. On July 23, 1970, Qaboos bin Said, son of the Sultan, staged a bloodless "coup d'état" in the Salalah palace with the assistance of the British, and took over as ruler.
