Tibetan armies invaded Bhutan around 1629, in 1631, and again in 1639, hoping to throttle Ngawang Namgyal's popularity before it spread too far. In 1634 Ngawang Namgyal defeated Karma Tenkyong's army in the Battle of Five Lamas. The invasions were thwarted, and the Drukpa subsect developed a strong presence in western and central Bhutan, leaving Ngawang Namgyal supreme. In recognition of the power he accrued, goodwill missions were sent to Bhutan from Cooch Behar in the Duars (present-day northeastern West Bengal), Nepal to the west, and Ladakh in western Tibet. The ruler of Ladakh even gave a number of villages in his kingdom to Ngawang Namgyal.
