Sri Lanka gained independence from British rule in 1948 and has since been a democratic republic. The country has faced a number of challenges, including civil war, natural disasters, and economic struggles. The civil war, which lasted from 1983 to 2009, was fought between the government and the Liberation Tigers of Tamil Eelam, a militant group seeking an independent state for the Tamil minority in the north and east of the island. The conflict ended with the defeat of the Tamil Tigers, but tensions between the Sinhalese majority and Tamil minority remain.

Sri Lanka has a mixed economy that relies heavily on agriculture, with tea, rubber, and coconut being major exports. The country is also known for its textiles, gemstones, and tourism industry. It is a member of the South Asian Association for Regional Cooperation and the World Trade Organization, and has strong economic ties with India and China.

Geopolitically, Sri Lanka is important due to its strategic location along major sea routes in the Indian Ocean. It is also a member of the Non-Aligned Movement, which aims to remain neutral in international relations. However, the country has faced pressure from larger powers in the region, including India and China, which have sought to influence its domestic and foreign policies.

Geography & terrain

An island whose coastal plains encircle a mountainous, forested central highland. Climate is tropical and monsoon-driven, wetter in the southwest. As an island nation it has no land borders and a coastline all around. Insularity has historically shielded it from land invasion and let interior highland kingdoms retreat inland, though it has always remained exposed to naval powers controlling the surrounding Indian Ocean routes.
