s began with the work of H.C.P. Bell, a British commissioner of the Ceylon Civil Service. Bell was shipwrecked on the islands in 1879, and returned several times to investigate ancient Buddhist ruins. He studied the ancient mounds, called havitta or ustubu (these names are derived from chaitiya and stupa) (Dhivehi) by the Maldivians, which are found on many of the atolls. Although Bell asserted that the ancient Maldivians had followed Theravada Buddhism, many local Buddhist archaeological remains now in the Malé Museum in fact also display elements of Mahayana and Vajrayana iconography.
In the early 11th century, the Minicoy and Thiladhunmathi, and possibly other northern Atolls, were conquered by the medieval Chola Tamil emperor Raja Raja Chola I, thus becoming a part of the Chola Empire.
According to a legend from Maldivian folklore, in the early 12th century AD, a medieval prince named Koimala, a nobleman of the Lion Race from Sri Lanka, sailed to Rasgetheemu island (literally "Town of the Royal House", or figuratively "King's Town") in the North Maalhosmadulu Atoll, and from there to Malé, and established a kingdom. By then, the Aadeetta (Sun) Dynasty (the Suryavanshi ruling cast) had for some time ceased to rule in Malé, possibly because of invasions by the Cholas of Southern India in the tenth century. Koimala Kalou (Lord Koimala), who reigned as King Maanaabarana, was a king of the Homa (Lunar) Dynasty (the Chandravanshi ruling cast), which some historians call the House of Theemuge. The Homa (Lunar) dynasty sovereigns intermarried with the Aaditta (Sun) Dynasty. This is why the formal titles of Maldive kings until 1968 contained references to "kula sudha ira", which means "descended from the Moon and the Sun". No official record exists of the Aadeetta dynasty's reign. Since Koimala's reign, the Maldive throne was also known as the Singaasana (Lion Throne). Before then, and in some situations since, it was also known as the Saridhaaleys
