Because of the combination of a relatively small Omani population and a fast-growing oil-driven economy, Oman has attracted many migrants. At the 2014 census the total expatriate population was 1,789,000 or 43.7% of the population. Most migrants are males from India (465,660 for both sexes), Bangladesh (107,125) or Pakistan (84,658). Female migrant workers are mainly from Indonesia (25,300), the Philippines (15,651) or Sri Lanka (10,178). Migrants from Arab countries account for 68,986 migrants (Egypt 29,877, Jordan 7,403, Sudan 6,867, UAE 6,426, Iraq 4,159, Saudi Arabia 725, Bahrain 388, Qatar 168, other 12,683) and other Asian countries for 12,939 migrants. There were 8,541 migrants from Europe, 1,540 from the United States and 15,565 from other countries.

The Jurchens were a Tungusic-speaking group of semi-agrarian tribes inhabiting areas of northeast Asia that are now part of Northeast China. Many of the Jurchen tribes were vassals of the Liao dynasty , an empire ruled by the nomadic Khitans that included most of modern Mongolia, a portion of North China, Northeast China, northern Korea, and parts of the Russian Far East. To the south of the Liao lay the Han Chinese Song Empire . The Song and Liao were at peace, but since a military defeat to the Liao in 1005, the Song paid its northern neighbor an annual indemnity of 200,000 bolts of silk and 100,000 ounces of silver. In 1114, the chieftain Wanyan Aguda united the disparate Jurchen tribes and led a revolt against the Liao. In 1115 he named himself emperor of the Jin "golden" dynasty . Informed by a Liao defector of the success of the Jurchen uprising, the Song emperor Huizong and his highest military commander the eunuch Tong Guan saw the Liao weakness as an opportunity to recover the Sixteen Prefectures, a line of fortified cities and passes that the Liao had annexed from the Shatuo Turk Later Jin in 938, and that the Song had repeatedly but unsuccessfully tried to reconquer. The Song thus sought an alliance with the Jin against their common enemy the Liao.

What did Tong Guan want to take back?
A: the Sixteen Prefectures
