The 1959 Uprising marked the first spontaneous popular Tibetan uprising against Chinese invasion of Tibet. Almost the entire citizenry of Lhasa, the capital of Tibet, assembled in front of Norbulingka, the summer palace, to protect their leader His Holiness the 14th Dalai Lama and to demand that the Chinese army leave Tibet. Since 1959, Tibetans inside Tibet and in exile have marked the National Tibetan Uprising Day.
