The island was subject to waves of European settlement and eventually colonisation. The Portuguese in the 16th and 17th centuries, the Dutch in the 17th and 18th centuries, and lastly the British from 1796 to 1948. The British traded as the others had done, but also developed plantations of coffee and tea. Tea was planted after a fungus destroyed the coffee plantations in 1869. The tea plantations were the basis of Sri Lankan prosperity for a hundred years. Lastly, rubber plantations were started in the early 20th century. In 1965, Ceylon became the world's leading exporter of tea, with 200,000 tonnes of tea being shipped internationally annually.
