The history of Sri Lanka begins around 30,000 years ago. Chronicles, including the Mahawansa, the Dipavamsa, the Culavamsa and the Rajaveliya, record events from the beginnings of the Sinhalese monarchy in the 6th century BC, the Tamil Elara (monarch) in the 2nd century BC; through the arrival of European Colonialists in the 16th century; and to the disestablishment of the monarchy in 1815. Some mentions of the country are found in the Ramayana, the Mahabharatam and the Lankavatara Sutra Mahayana Buddhism texts of the Buddha's teachings. Buddhism was introduced in the 3rd century BC by Arhath Mahinda (son of the Indian emperor Ashoka the Great). king asoka
