Influenced by both Mahatma Gandhi's philosophy of non-violence and more specifically by Buddhist concepts, Aung San Suu Kyi entered politics to work for democratization, helped found the National League for Democracy on 27 September 1988, but was put under house arrest on 20 July 1989. She was offered freedom if she left the country, but she refused. Despite her philosophy of non-violence, a group of ex-military commanders and senior politicians who joined NLD during the crisis believed that she was too confrontational and left NLD. However, she retained enormous popularity and support among NLD youths with whom she spent most of her time.
