'Monlam' also known as The Great Prayer Festival, falls on 4th -11th day of the 1st Tibetan month in Tibetan Buddhism. The event in Tibet was established in 1409 by Tsong Khapa, the founder of the Geluk tradition. As the greatest religious festival in Tibet, thousands of monks (of the three main monasteries of Drepung, Sera and Ganden) gathered for chanting prayers and performing religious rituals at the Jokhang Temple in Lhasa. During the Cultural Revolution, the monlam festival was banned, and although it was revived once in 1985, it was prohibited again in 1990 by the Chinese government.
