Lhoka's history is the history of Tibetan civilization itself. According to Tibetan tradition, the first Tibetan king, Nyatri Tsenpo, descended from heaven onto the sacred mountain Yarlha Shampo in the Yarlung Valley around 127 BC. His descendants established the Yarlung dynasty, which would eventually unify Tibet under Songtsen Gampo in the 7th century AD.
The 7th and 8th centuries were transformative for Lhoka. King Songtsen Gampo built the Yumbulagang Palace and Tradruk Temple. In 779 AD, King Trisong Detsen founded Samye Monastery, marking the formal establishment of Buddhism in Tibet. The great Indian master Padmasambhava (Guru Rinpoche) was invited to consecrate the monastery and tame the local spirits according to legend.
During the later imperial period, Lhoka remained an important religious and cultural center. Many of Tibet's most revered Buddhist masters studied and taught at Samye Monastery. In modern times, Lhoka has seen significant development while preserving its archaeological treasures. The region has become a major center for Tibetan studies and cultural preservation.
