On Pohnpei, pre-colonial history is divided into three eras: "Mwehin Kawa" or "Mwehin Aramas" (Period of Building, or Period of Peopling, before c. 1100); "Mwehin Sau Deleur" (Period of the Lord of Deleur, c. 1100 to c. 1628); and "Mwehin Nahnmwarki" (Period of the Nahnmwarki, c. 1628 to c. 1885). Pohnpeian legend recounts that the Saudeleur rulers, the first to bring government to Pohnpei, were of foreign origin. The Saudeleur centralized form of absolute rule is characterized in Pohnpeian legend as becoming increasingly oppressive over several generations. Arbitrary and onerous demands, as well as a reputation for offending Pohnpeian deities, sowed resentment among Pohnpeians. The Saudeleur Dynasty ended with the invasion of Isokelekel, another semi-mythical foreigner, who replaced the Saudeleur rule with the more decentralized "nahnmwarki" system in existence today. Isokelekel is regarded as the creator of the modern Pohnpeian "nahnmwarki" social system and the father of the Pompeian people.
