Buddhism plays an eminent political role in Sri Lanka and serves as a unifying force for the Sinhalese majority . Although the monks must renounce worldliness, they of necessity maintain close relationships with the lay community, whose members must supply them with food, shelter, and clothing. During the past century, as Sinhalese nationalism fueled lay devotion to Buddhism, there was a proliferation of lay support organizations, such as the All-Ceylon Buddhist Congress, the Colombo Buddhist Theosophical Society, the All-Ceylon Buddhist Women's Association, and the Young Men's Buddhist Association. The state has similarly retained close ties with the sangha (see Glossary). Since the time of Asoka, the first great Indian emperor (third century B.C.), the head of state has been seen by Buddhist thinkers as the official protector of Buddhism, the "turner of the wheel of the law" (see Historical Perspective, 1802-1978 , ch. 4). One of the recurring problems in the history of Sri Lanka has been a definition of the state as the official supporter of Buddhism, which in turn has been the religion of the ethnic Sinhalese. To be successful among the Sinhalese, a government must provide visible signs of its allegiance to the sangha by building or maintaining dagoba, judging disputes among the orders of monks, and fostering education in the Pali Buddhist tradition.

Individual monks and entire sects have involved themselves in party politics, but seldom do all families and orders unite behind a coherent policy. When they do unite, they are a potent political force. In 1956, for example, a rare union of monastic opinion gave crucial support to the election of the Sinhalese political leader Solomon West Ridgeway Diaz (S.W.R.D.) Bandaranaike (see Sri Lanka Freedom Party Rule, 1956-65 , ch. 1). As of 1988, the sangha controlled extensive estates in the interior of Sri Lanka and retained an independent power base that, combined with high status in the eyes of the Sinhalese population, gave the Buddhist orders influence as molders of public opinion. Monks remained prominent at rallies and demonstrations promoting ethnic Sinhalese issues.
