The Dalai Lama is the spiritual leader of Tibet. He was born on  July 6, 1935, to a farming family, in a small hamlet located in Taktser, Amdo, northeastern Tibet.

At the age of two, the child, then named Lhamo Dhondup, was recognised as the reincarnation of the previous 13th Dalai Lama, Thubten Gyatso.

In 1950, after China's invasion of Tibet, he was called upon to assume full political power. In 1959, he was forced to escape into exile. Since then, he has been living in Dharamsala.
