The earliest well-documented influence of Buddhism in Tibet dates from the reign of king Songtsän Gampo, who died in 650. He married Buddhist princesses from Nepal (Bhrikutidevi) as well as Tang Dynasty China (Wencheng), among other wives; and founded the first Buddhist temples (including the Jokhang). By the second half of the 8th century he was already regarded as an embodiment of the bodhisattva Avalokiteshvara. One aspect of Buddhism's appeal (as opposed to that of state Bön) was its international character, as a religion of the major trade routes to India and Central Asia.
