How did communist China assert control over Tibet after 1949?

Following the communist takeover of China in 1949, the new government asserted that Tibet was part of the "Chinese motherland" and initiated efforts to consolidate control over the region.12

The process of asserting control involved several key actions:

• Military Intervention: In October 1950, the People’s Liberation Army entered and took control of eastern Tibet, overwhelming local forces.12
• The Seventeen-Point Agreement: In May 1951, a Tibetan delegation in Beijing was compelled to sign a treaty under duress. This agreement formally ceded control to China while professing to guarantee Tibetan autonomy and religious freedom.12
• Administrative Presence: The treaty allowed for the establishment of Chinese civil and military headquarters in Lhasa, leading to an influx of Chinese soldiers and civilians.1
• Suppression of Resistance: Attempts to collectivize monastic properties in eastern Tibet triggered violent resistance. Following a popular uprising in Lhasa in March 1959, the Chinese government suppressed the movement, leading to the 14th Dalai Lama’s escape into exile.21

Subsequent decades saw further integration through infrastructure development, such as highway and railroad construction, alongside periods of intense political control, including during the Cultural Revolution.13
