Tibet was a "de facto" independent state that lacked international recognition. It remained neutral throughout the war. The 14th Dalai Lama, Tenzin Gyatso, was enthroned by the Ganden Phodrang government at the Potala Palace in 1939. Tibet established a Foreign Office in 1942, and in 1946 it sent congratulatory missions to China and India related to the end of the war. Its era of independence ended after the Nationalist government of China lost the Chinese Civil War and the People's Liberation Army entered Tibet in 1950.
