Colonial era

Sri Lanka had always been an important port and trading post in the ancient world, and was increasingly frequented by merchant ships from the Middle East, Persia, Burma, Thailand, Malaysia, Indonesia and other parts of Southeast Asia. The islands were known to the first European explorers of South Asia and settled by many groups of Arab and Malay merchants.

A Portuguese colonial mission arrived on the island in 1505 headed by Lourenço de Almeida, the son of Francisco de Almeida. At that point the island consisted of three kingdoms, namely Kandy in the central hills, Kotte at the Western coast, and Yarlpanam (Anglicised Jaffna) in the north. The Dutch arrived in the 17th century. Although much of the island came under the domain of European powers, the interior, hilly region of the island remained independent, with its capital in Kandy.

The British East India Company established control of the island in 1796, declaring it a crown colony in 1802, although the island would not be officially connected with British India. The fall of the kingdom of Kandy in 1815 unified the island under British rule.
