Buddhism was first introduced to Bhutan in the 7th century AD. Tibetan king Songtsän Gampo (reigned 627–649), a convert to Buddhism, who actually had extended the Tibetan Empire into Sikkim and Bhutan, ordered the construction of two Buddhist temples, at Bumthang in central Bhutan and at Kyichu (near Paro) in the Paro Valley. Buddhism was propagated in earnest in 746 under King Sindhu Rāja ("also" Künjom; Sendha Gyab; Chakhar Gyalpo), an exiled Indian king who had established a government in Bumthang at Chakhar Gutho Palace.
