During the reign of Tibet's king Trisong Deutsen in the 8th century, the Gyalrong area was visited by the great translator Vairotsana. In 1410 Je Tsongkhapa's student Tshakho Ngawang Tapa established the first Tibetan Buddhist Gelug school monastery in the area, called "Gyalrong". In contemporary history, most of Ngawa was under the 16th Administrative Prefecture of Szechwan (), which was established by the Republic of China (ROC). The People's Republic of China defeated ROC troops in this area during Chinese Civil war and subsequently established a Tibetan autonomous prefecture by late 1952. It was renamed Aba Tibetan Autonomous Prefecture in 1956 and Aba Tibetan and Qiang Autonomous Prefecture in 1987. On May 12, 2008, a major earthquake occurred in Wenchuan County (), a county in the southeastern part of this autonomous prefecture. 20,258 people were killed, 45,079 injured, 7,696 missing in the prefecture as of June 6, 2008. In 2009, the town of Ngaba in Ngawa prefecture became the self-immolation capital of the world. From 2009 to 2019, more than 60 of Tibet's total 156 self-immolations occurred in Ngaba. By 2020, the town's entrances were barricaded and surveillance cameras installed, with some 50,000 security personnel for the town's population of 15,000. In 2008, Aba county was stripped of its internet connections. Internet access in the prefecture remains severely restricted as of 2013. Geography
