The history of Tibet had a significant impact on shaping Tibetan culture. Tibetan Buddhism became the dominant religion after it was introduced in the 7th century. Over time, religion and politics became intertwined as the Dalai Lama rose to power. When China conquered Tibet in the 1950s, it challenged Tibetan culture and religion but also invested in infrastructure to strengthen its control. Tibetan culture is now influenced by both religion and material interests.
