Mayapan became the primary city in a group of allies that included much of the northern Yucatán, and trade partners that extended directly to Honduras, Belize, and the Caribbean island of Cozumel, and indirectly to Mexico. Though Mayapan was ruled by a council, the "Jalach winik" and the "aj k’in" (the highest ruler, and the high priest) dominated the political sphere. Below the two primary officials were many other officials with varying responsibilities. The range of classes went from the nobility, down to slaves, with intermediary classes in between. The social climate of Mayapan was made complicated by the antagonistic relationship between the factions of nobles, which were often arranged by kinship (Pugh 2009; Milbrath 2003). In 1441, Ah Xupan of the powerful noble family of Xiu became resentful of the political machinations of the Cocom rulers and organized a revolt. As a result, all of the Cocom family, except one who was away in Honduras conducting trade, were killed, Mayapan was sacked, burned, and abandoned, all the larger cities went into decline, and Yucatán devolved into warring city-states.
