Tibet was occupied by China in 1950 when the People’s Liberation Army entered the region, asserting control over it. This military action culminated in the 17-Point Agreement of 1951, which was signed under duress and led to the incorporation of Tibet into the People's Republic of China. The occupation has been marked by significant political, cultural, and social changes, leading to ongoing tensions and international concern regarding human rights in the region.
