The chief of the Cocom family, a rich and ancient lineage that had taken part in the revolt against Chichen, was chosen to be king, and all the other noble families and regional lords were to send members of their families to Mayapan to play parts in the government (and perhaps act as hostages for the good behavior of the subsidiary cities). Mexican mercenaries from Tabasco were also employed to keep order and maintain power. Another family, the Xiu, may have been living in the Mayapan area prior to the arrival of the Cocom; the Xiu claim to be a part of the lineage from Uxmal. This arrangement lasted for over 200 years. (An alternative account is given in a Maya chronicle from the Colonial era, claiming that Mayapan was contemporary with Chichen Itza and Uxmal and allied with those cities, but archeological evidence shows this version to be less likely.)
