The policy of majoritarianism in Sri Lanka led to several consequences, both positive and negative. Let's discuss them in detail below:

Background:

Majoritarianism is a political philosophy that asserts that a majority, usually from the dominant ethnic or religious group, should hold power within a society and make decisions on behalf of the entire population. In Sri Lanka, the majority Sinhalese community implemented this policy, which led to discrimination against the Tamil minority.

Consequences:

1. Discrimination against Tamils: The policy of majoritarianism led to discrimination against Tamils in Sri Lanka. The government passed several laws that favored the Sinhalese community over the Tamil community. For example, the "Sinhala Only Act" of 1956 made Sinhala the official language of Sri Lanka, which excluded Tamils from many jobs and educational opportunities.

2. Rise of Tamil nationalism: The discrimination against Tamils led to the rise of Tamil nationalism in Sri Lanka. The Tamil community felt that their rights were being ignored and that they were being treated as second-class citizens. This led to the formation of several Tamil militant groups that fought for a separate Tamil state in Sri Lanka.

3. Civil war: The policy of majoritarianism ultimately led to a civil war in Sri Lanka that lasted for over 25 years. The Tamil militant groups, such as the Liberation Tigers of Tamil Eelam (LTTE), fought against the Sri Lankan government to establish a separate Tamil state. The civil war resulted in the deaths of thousands of people and caused significant damage to the country's infrastructure.

4. International pressure: The civil war in Sri Lanka drew international attention, and several countries and organizations called for a peaceful resolution to the conflict. However, the Sri Lankan government was initially resistant to international pressure and continued its military operations against the Tamil militants.

5. End of the civil war: The civil war in Sri Lanka ended in 2009 when the Sri Lankan government launched a major military offensive against the LTTE. The government was able to defeat the LTTE, and the civil war came to an end. However, the end of the civil war did not resolve the underlying issues of discrimination and inequality that the Tamil community faced in Sri Lanka.

Conclusion:

In conclusion, the policy of majoritarianism in Sri Lanka led to discrimination against the Tamil minority, the rise of Tamil nationalism, a civil war, international pressure, and the end of the civil war. The consequences of this policy continue to impact Sri Lanka today, and the country must work towards resolving the underlying issues of discrimination and inequality to ensure lasting peace and prosperity for all its citizens.

The series of majoritarian measures adopted by the democratically elected government were as follows: 
(i) In 1956, an act was passed to recognise Sinhala as the official language thus disregarding Tamil.
(ii) The government followed preferential policies that favoured Sinhala applicants for university positions and government jobs.
(iii) A new Constitution stipulated that the state shall protect and foster Buddhism.
