Labrang Monastery
At the beginning of the 17th century, Tibetan Buddhism penetrated northward from Mongolia to reach the Buryat population of Transbaikalia (the area just east of Lake Baikal). Initially, Buddhism disseminated primarily among the ethnic groups that had recently migrated out of Khalkha Mongolia (the Selenga and Zede Buryats). At the end of the 17th to the beginning of the 18th centuries, it spread throughout the Transbaikal region. A second branch came directly from Tibet, from the Labrang Monastery in Amdo.
