Following Chichén Itzá’s decline, Mayapán rose as a dominant political and religious center in northern Yucatán, becoming closely associated with (or the seat of) a wider confederation of Maya polities later remembered as the League of Mayapán.
By the mid-13th century, Mayapán functioned as the political capital of a confederation of provinces in northwestern Yucatán, with substantial population aggregation and defensive works (including a large perimeter wall).
Chichén Itzá was largely abandoned as an urban center by the 13th century, though pilgrimage activity continued—an important shift that strengthened Mayapán’s position within regional politics.
Archaeological descriptions emphasize Mayapán as a dense walled city with thousands of structures, reflecting sustained urban growth and centralized authority in the Late Postclassic.
Historical syntheses describe the Cocom as dominant rulers at Mayapán during its peak centuries, with the city serving as a major seat of power in the northern Yucatán political system.
Multi-proxy research links prolonged drought conditions in the early-to-mid 15th century (roughly 1400–1450) with heightened instability and conflict at Mayapán, worsening existing factional tensions.
Archaeological and historical evidence indicates a pronounced interval of unrest and violence at Mayapán in the decades before its political collapse, consistent with elite factional competition and broader environmental pressure.
Ethnohistoric accounts date a decisive Xiu uprising/assault against the ruling Cocom faction to 1441, often described as a massacre that fatally undermined Mayapán’s governing order.
The confederated political system commonly called the League of Mayapán is widely described as collapsing around 1441, with power fragmenting across the northern Yucatán.
After the collapse, sources describe elites relocating and establishing independent jurisdictions (kuchkabals). One example is Ah Kin Chel, described as founded when Mo-Chel fled Mayapán amid the political rupture.
Historical records and scholarship commonly place Mayapán’s abandonment after its political collapse sometime between 1441 and 1461, reflecting a drawn-out disintegration rather than an instantaneous end.
In the aftermath of Mayapán’s collapse, the northern Yucatán is described as dividing into numerous independent polities (often summarized as around seventeen kuchkabals), shaping the political landscape encountered in the early colonial period.
