Tibet is located between China and India and functions as a Buddhist theocracy, with Tibetan Buddhism influencing daily life. The harsh terrain and climate means most Tibetans are nomadic herders or subsistence farmers. China invaded Tibet in 1951 and has since suppressed Tibetan culture and religion, destroying monasteries and forcing the Dalai Lama into exile. Tibetan Buddhism teaches that desire causes suffering and the cycle of rebirth, and the goal is to reach enlightenment and help others do the same.
