Koimala Siri Mahaabarana Mahaa Radun (Dhivehi: ކޮއިމަލާ ސިރީ މަހާބަރަނަ މަހާ ރަދުން) or Koimala (Dhivehi: ކޮއިމަލާ literally "flower lad") or Koimala Kalo (Dhivehi: ކޮއިމަލާ ކަލޯ, literally "Lord Koimala") is a legend about the first king of all the Maldive Islands.
Some versions of the legend claim that it refers to the first ruler of the Maldives after the conversion to Islam, also known as Dharumavantha rasgefaanu, who ruled from 1117 to 1141. It is believed that he was also 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 only ruled over 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 leaves without explaining the existence of an ancient kingly dynasty in the Maldives already before the conversion, as the 12th century correspondence from the king to the Sangumanun, or community of Buddhist monks, in Sathudhuvumati (Haddummati Atoll via copper plates proves.
According to Maldivian Folklore, Koimala was a prince from the Indian subcontinent who arrived in 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 fishblood. Trees were planted on the sandbank and it is said that the first tree that grew on it was the 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 (Malé), while the nearest island was named Hulhu-le (Hulhulé). Since then Malé has been the seat of the Maldivian crown and now the head of state.
