Golok conflicts (1917–1949)
The Amdo- Ma clique conflicts (1917–1949) were a series of military campaigns against unconquered Amchok and Ngolok (Golok) tribal Tibetan areas of Qinghai (Amdo), undertaken by two Hui commanders, Gen. Ma Qi and Gen. Ma Bufang, on behalf of the Beiyang and Kuomintang governments of the Republic of China. The campaigns lasted between 1917 and 1949. The conflict was spurred by multiple factors, notably for economic and socio-political reasons (including intertribal tensions) rather than by any racial or religious enmity. The War. Gen. Ma Qi was a Hui Chinese commander who joined the Kuomintang after the  Northern Expedition in 1927–1928. His forces were composed entirely of Hui Chinese, organized in the Ninghai Army, which was then turned into a National Revolutionary Army division. Battles for Labrang. Ma Qi occupied Labrang Monastery in 1917, the first time non-Tibetans had seized it. Ma Qi defeated the Tibetan forces with his Hui Chinese troops. His forces were praised by foreigners who traveled through Qinghai for their fighting abilities. The Labrang monastery had strong connections to the unpacified Ngolok Tibetan tribals who refused to submit to Chinese rule unlike the other Tibetans of Qinghai. After ethnic rioting between Hui  and Tibetans erupted in 1918, Ma Qi defeated the Tibetans. He heavily taxed the town for eight years. In 1925 a rebellion broke out, and thousands of Tibetans drove out the Hui. Ma Qi responded with 3,000 Hui Chinese troops, who retook Labrang and machine-gunned thousands of Tibetan monks as they tried to flee. Ma Qi besieged Labrang numerous times but the Tibetans and Mongols fiercely resisted his Hui forces until Ma Qi gave it up in 1927. However, that was not the last Labrang saw of Gen. Ma. The Hui forces looted and ravaged the monastery again. In  revenge Tibetan Nomads skinned alive many Hui soldiers. One of the most common practices was to slice open the stomach of a still alive soldier and then put hot rock inside the stomach. Many hui women were sold to the ethnic Han and Kazakhs. Children were adopted by the Tibetans. Austrian-American explorer Joseph Rock witnessed the carnage and aftermath of one of the battles around 1929. The Ma Muslim army left Tibetan skeletons scattered over a wide area, and the Labrang monastery was decorated with decapitated Tibetan heads. After the 1929 Battle of Xiahe near Labrang, decapitated Tibetan heads  were used as ornaments by Chinese Muslim troops in their camp, 154 in total. Rock described how the heads of "young girls and children" were staked around the encampment. Ten to 15 heads were fastened to the saddle of every Muslim cavalryman. The heads were "strung about the walls of the Moslem garrison like a garland of flowers." Ma Bufang's campaigns. Ma Bufang, the son of Ma Qi, was a Kuomintang warlord who dominated Qinghai. He served as a general in the National Revolutionary Army and sought to expand the Republic of China's control over all of Qinghai , as well as bringing Tibet back into the Republic by force. When Ma Bufang launched seven expeditions into Golog, killing thousands of Ngolok Tibetans, the Republic of China government, known as the Kuomintang, supported him. Ma and his army exterminated many Ngolok Tibetans in northeastern and eastern Qinghai. During one such attack in 1941 Ma Bufang sent Chinese Hui troops to destroy Sekar Gompa monastery, killing their highest ranking Lama and 300 tapas. They sacked the compound, burning it to the ground, and sold all of the property for gold and silver. From 1918 to 1942 the Ma warlords waged  intensive, violent war against the Ngolok tribal inhabitants of Golog. Ma Bufang also manufactured conflicts by giving pasture to Tibetan and Mongolian groups at the same time, which spread disunity. The Kunlun middle school was established by Ma Bufang, and it recruited Tibetan students, who were subjected to a harsh military life. Ma wanted to use them as translators as he expanded his military domain over land inhabited by Tibetans. During the pacification, a war broke out between Qinghai and Tibet. Tibet attempted to capture parts of southern Qinghai province, following contention in Yushu, Qinghai, over a monastery in 1932 . Ma Bufang's army vanquished the Tibetan forces and recaptured several counties in Xikang Province. Tibetan tribals in southern Qinghai revolted due to taxation against Ma Bufang in 1939–1941, but they were crushed by "suppression campaigns" and massacred by Ma Bufang which caused a major influx of Tibetan refugees into Tibet from Qinghai. Under orders from the Kuomintang government of Chiang Kai-shek, Ma Bufang repaired the Yushu airport in southern Qinghai Province, close to the border with Tibet, to prevent Tibetan separatists from seeking independence. Chiang also ordered Ma Bufang to put his Hui soldiers on alert for an  invasion of Tibet in 1942. Ma Bufang complied, and moved several thousand troops to the border with Tibet (1912–1951). Chiang also threatened the Tibetans with aerial bombardment if they did not comply. A former Tibetan Khampa soldier named Aten who fought Ma Bufang's forces gave an account of a battle. He described the Chinese Muslims as "fierce". After he and his troops were ambushed by 2,000 of Ma Bufang's Chinese Muslim cavalry, he was left with bullet wounds and "had no illusions as to the fate of most of our group", the majority of whom were wiped out . Aten also asserted that "the Tibetan province of Amdo" was "occupied" by Ma Bufang.
