Following Indian independence in 1947, Kalimpong became part of the state of West Bengal, after Bengal was partitioned between India and East Pakistan. With China's annexation of Tibet in 1959, many Buddhist monks fled Tibet and established monasteries in Kalimpong. These monks brought many rare Buddhist scriptures with them. In 1962, the permanent closure of the Jelep Pass after the Sino-Indian War disrupted trade between Tibet and India, and led to a slowdown in Kalimpong's economy. In 1976, the visiting Dalai Lama consecrated the Zang Dhok Palri Phodang monastery, which houses many of the scriptures.
