The first introduction of Buddhism in Bhutan was occurred in the seventh century A.D., when Tibetan king Srongtsen Gampo (reigned from A.D. 627-649), a converted Buddhist, ordered the construction of two Buddhist temples, at Bumthang and Paro.
According to Bhutanese tradition, Guru Rimpoche plays an essential and religious role as Bhutan patron saint for Buddhism foundations in Bhutan.
In A.D. 747, Padmasambhava (Guru Rimpoche), came to Bhutan from India at the invitation of the local kings to subdue the demons and evil spirits terrorizing the villagers. The demon and evil spirits converted of their own accord and bound under oath to become Dharma protectors.
Soon after, Guru Rimpoche moved on to Tibet and oversaw the construction of new monasteries in the Paro Valley and his Bumthang headquarters.
