Salalah was the traditional capital of Dhofar, which reached the peak of prosperity in the 13th century thanks to the incense trade. Later it decayed, and in the 19th century it was absorbed by the Sultanate of Muscat. Between 1932 and 1970, Salalah was the capital of the Sultanate of Muscat and Oman under Said bin Taimur. After the latter's death, his son Qaboos decided to move the capital of Oman to Muscat.
The Sultan traditionally lives in Salalah rather than in Muscat, the capital and largest city in Oman; Qaboos has bucked this trend, and has lived in Muscat since he ascended to the throne in 1970. He does, however, visit Salalah fairly regularly to meet with influential tribal and local leaders; his last visit was in 2010 and before that he visited in 2006.
In 2010, during the 40th anniversary of Sultan Qaboos' taking the throne, he decided to spend his time in Salalah. The 40th anniversary celebrations consisted of a massive parade. It lasted several hours and had an estimated 100,000 attendees. In 2011 the city hosted peaceful protests after the domino effect from the Arab Spring which lasted several months. Of the many requests filed from the protesters, some included the expulsion of the current ministers, job opportunities, salary increases, a solution to the increasing cost of living, and the establishment of Islamic banks
