Draft:Yang Maosou

Yang Maosou (died 317), originally named Linghu Maosou, was the founding ruler of the Di-led Chouchi state. A member of the Linghu clan, he was adopted by his uncle, the Di chieftain, Yang Feilong, and succeeded him in 296. That same year, he led his followers to Chouchi and established a small independent state that would last until 443. He is also known as Yang Wusou in some records.

Background
Yang Maosou was the nephew of the Di chieftain, Yang Feilong. Their ancestors had previously resided in the Chouchi region, but during the reign of Emperor Wu of Jin, Feilong resettled the clan in Qingshui County, Lüeyang Commandery (略陽郡; roughly modern-day Tianshui, Gansu). Feilong was unable to conceive a son, so he adopted the son of his sister, Lady Linghu (令狐氏). He then changed his adopted son's name to Yang Maosou (or Yang Wusou). Feilong died in 296, and Yang Maosou succeeded him as the new chief.

Reign
That same year, another Di chieftain, Qi Wannian, led a tribal rebellion against Jin that, along with coinciding famines, devastated Qinzhou and Yongzhou. Around the end of 296, Yang Maosou decided to move back to his ancestral homeland in Chouchi to escape the confusion, bringing with him 4,000 families. He declared himself General Who Upholds the State and Worthy Prince of the Right, and soon, many refugees from the Guanzhong region also decided to join him. Maosou welcomed the refugees with open arms and allowed them to leave if they wanted to, even providing them with resources to protect themselves on the way out.

Later, Emperor Min of Jin legitimized Maosou's authority by appointing him General of Agile Cavalry and Worthy Prince of the Left. Maosou's son, Yang Nandi, was also appointed General Who Attacks the South by the Prince of Nanyang, Sima Bao.

In 313, Jin's Inspector of Liangzhou, Zhang Guang, campaigned against the rebel leader, Yang Hu (楊虎). Both sides approached Yang Maosou to form an alliance, and Maosou decided to back Zhang Guang. He sent Yang Nandi to aid Jin, but Nandi betrayed Zhang Guang and joined forces with Yang Hu instead. Nandi defeated Zhang Guang and briefly controlled Hanzhong before being ousted back to Chouchi by a local revolt in 314.

Yang Maosou died around the end of 317. Yang Nandi, being Maosou's eldest son, succeeded him, but decided to jointly rule Chouchi with his brother, Yang Jiantou (楊堅頭).
