“Some of the Maya who migrated went north, attracted by a new religion revolving around Kukulcan and trade centered at Chichén Itzá…” (Lucero 2006:192)
Migration has always been popular in explaining social processes in archaeology. In the Maya area, the southern or central lowland is usually the core area from where everything else is interpreted. The northern lowland is therefore seen to reflect processes going on further south. Santley and others once proposed an outmigration from Yucatan during the late Late Formative due to a drier climate. Therefore they argue that there were no settlement increases in the Yucatan until Late and Terminal Classic, and this increase is explained by people from the south moving back to the north again. Some areas may of course have experienced population increase or decrease due to migration but this is not strongly supported by ceramics.
I am sceptical to such long-distance migration models but I think that local dispersion and congregation of settlement did occur. Ichmul and Yo’okop had substantial settlements during the Classic period whereas the smaller sites in the Cochuah region had no or little occupation during the same period. I therefore have problems with Lucero’s statement. I do not believe that people migrated in large groups because they desired to be part of the “Kukulcan/Quetzalcoatl” cult (which Ringle and others state is a royal ideology and had less impact on the majority of emigrants). This feels like a comparative analogy with missionary religions in the Old World (Christianity, Islam, and Buddhism). Neither was the trade something they could live on. If there was a migration to the north (and there is not much evidence for this) they probably had something else in mind than trade and religion. Maybe they just needed new lands. Or, as I believe, there were no great migrations by large groups.
