Koimala Siri Mahaabarana Mahaa Radun or Koimala or Koimala Kalo is the last pre-Islamic and the earliest verifiable ruler of the Maldives. He reigned from A.D. 1117 to A.D. 1141. According to the Isdhoo Loamaafaanu, he unified the Maldives from Minicoy to Addu in the south under his rule. Local folklores claim that he was the first Muslim ruler, however it is his successor, Dhovemi of the Maldives, who converted to Islam in 1153.
Legend
Some versions of his legend claim that it refers to the first ruler of the Maldives after the conversion to Islam, Dharumavantha rasgefaanu, who ruled from 1117 to 1141. It is believed that he was the first king from the House of Theemuge and the Lunar Dynasty. By other accounts he was the fourth king of the Lunar Dynastry founded by King Balaadeettiya as the Soma Vansa Kingdom, although until Koimala the house ruled over only part of the Maldives. However, ascribing the legend to the first Islamic ruler does not explain who built the large Buddhist monuments that are present in many inhabited islands and that were built in the first millennium AD. It also does not explain the existence of an ancient kingly dynasty in the Maldives before the conversion, as evidenced by the 12th century correspondence from the king to the Sangumanun, or community of Buddhist monks, in Sathudhuvumati According to Maldivian Folklore, Koimala was a prince from the Indian subcontinent who arrived in the Malé Atoll. The people of Giraavaru spotted his vessel from afar and welcomed him. They allowed Prince Koimala to settle on that large sandbank in the midst of the waters tainted with fish blood. Trees were planted on the sandbank and the first tree that grew on it was a papaya tree. As time went by the local islanders accepted the rule of this northern prince. A palace was built and the island was formally named Maa-le, while the nearest island was named Hulhu-le. Since that time Malé has been the seat of the Maldivian crown and is now the seat of the President of the Maldives. A different account claims Koimala to be a Sinhalese prince of royal birth from Ceylon. The prince is said to have married the king of Ceylon's daughter and made a voyage with her in two vessels from the island. Reaching the Maldives they became becalmed, and rested at Rasgetheemu island and Angolhitheem island in Northern Maalhosmadulhu Atoll. The Maldive islanders who were then Buddhists, learning that the two chief visitors were of royal descent from the Buddhist kingdom of Ceylon, invited them to remain and ultimately proclaimed Koimala their king at Rasgetheemu. The new king and his spouse migrated to Malé and settled there with the consent of the aborigines of Giraavaru - then the most important community of Malé Atoll. Until then the Maldives is thought to have been ruled by various matriarchies in different atolls. After the settlement in Malé, two vessels were dispatched to bring more people of his race to populate Malé. It was not in the tradition for the Giraavaru, and perhaps other aboriginal people of the Maldives, to marry outside their community. Although he might have been the first king of the whole of Maldives, the story of a prince might instead be a corruption of the stories of King Soorudasaruna-Adeettiya and King Balaadeettiya, both exiled princes from the Kalinga Kingdom of India who founded the Solar and Lunar Dynasties of the Maldives. According to this source, Koimala or Siri Mahaabarana, the son of King Siri Bovana Aananda was the fourth king of the Lunar Dynastry and uncle to King Dhovemi the first Sultan of the Maldives. Koimala's kingdom was referred to as Malikaddu dhemedhu- or 'all that lies between the Maliku and Addu'. He fought against the Raja Dada'Indians to claim the two northern most atolls for the newly formed Maldivian kingdom. The atolls from the north to south were then named:
