The Rule of Bome King

　　At about 300 years ago, Mamba people started to migrate to Medog from Moinyu and Zhuyu. The earliest immigrants have had 12 generations in Medog; the latest ones also have had 8 generations there. As the Mamba people increase in population, at the later half of the 19^th century, in order to contend for land and hunting fields, Mamba people and Lhoba people often had disputes and fighting. The King of Bome, who was quite ambitious, continued to enlarge its strength in this area. By making use of the chance when these two peoples were fighting, he established Didongzong and Galangyangzong governments near Medog. Its strength was enlarged to Lower Luoyu district and he gradually brought Medog and the Great Canyon region under his control. 

　　The Qing Dynasty government, for many times, sent troops to help the local government of Tibet to wipe out the Bome King. The Bome King surrendered several times, but he always went back to his words. Bome King thought that the place he lived was scary and desolate, and his subjects were fierce; thus no one could hurt him. He often led his men go out to loot every now and then. By the 1920s and the 1930s, the local government of Tibet again sent large amount of troops to wipe the Bome Kindom out. They defeated the Bome King completely. From then on, Bome was always under the jurisdiction of Tibet. Afterwards, the local Tibetan government entrusted Didongzong (a administrative region) to the management of Sela Temple, which made great contributions in fighting with the Bome King; and assigned Bangxing (a administrative region) and Jialas (a administrative region) as the land of Qiongduo Temple and Jainzhag district to the management of Songguo Temple.

　　Before the rule of the Bome King, the Mamba people in Medog were still in the primitive society. Their land was possessed naturally. After Bome King established local governments there, he checked up the land and reallocated the land of the Mamba people to ensure his taxes.
