When or why was dalai lama forced to leave china?

The Dalai Lama was forced to leave Tibet and seek refuge in India in March 1959, following a failed uprising against Chinese rule. Fearing for his life amid escalating tensions between Tibetan rebels and Chinese forces, he fled to India where he was granted asylum. His departure marked a significant moment in the Tibetan struggle for autonomy and has led to ongoing international attention regarding human rights and cultural preservation in Tibet.
