Sri Lanka got freedom in 1948. They followed the democratic rule over the country and adopted a policy of majoritarianism. They established Sinhala supremacy and neglected the Sri Lankan Tamils after independence.
(i) Sinhala became the official language of Sri Lanka in 1956 after passing an act.
(ii) The government provides preference to Sinhala community in all kinds of job.
(iii) Buddhism became the state religion. Sri Lankan Tamils felt that all political parties led by Buddhist Sinhala leaders were sensitive to their religion and language. They denied equal political rights to Tamils. So, they launched parties and struggled against them for regional autonomy and equality of opportunity. This struggle between two in Sri Lanka turned in to civil war.
