For centuries, Bhutan was made up of feuding regions until it was unified under King Ugyen Wangchuck in 1907. The British exerted some control over Bhutan's affairs, but never colonized it. Until the 1960s Bhutan was largely isolated from the rest of the world, and its people carried on a tranquil, traditional way of life, farming and trading, which had remained intact for centuries. After China invaded Tibet, however, Bhutan strengthened its ties and contact with India in an effort to avoid Tibet's fate. New roads and other connections to India began to end its isolation.
