The Saudeleur Dynasty was a ruling dynasty in the ancient Pacific island of Pohnpei, part of the Federated States of Micronesia. It is believed to have existed from around the 12th century until the 19th century. The dynasty is known for its significant contributions to the development of Pohnpei's culture, governance, and monumental architecture, including the famous Nan Madol complex. The rulers of the Saudeleur Dynasty were known for their centralized authority and control over the island's resources. They established a complex social hierarchy and engaged in trade with neighboring islands. The dynasty eventually declined due to internal strife and external pressures, leading to its eventual fall in the 19th century.
