Settlement and political structure in the Classic Maya Rosario polity are analyzed within a multistep research scheme (originally devised for political anthropology). Single variables arranged along continua are used to conceptualize political structure, in preference to multivariate societal types. Emphasis is given to political centralization and its implementation through forced settlement of subject population into political centers. Settlement nucleation measures for the Rosario polity and its subunits depend on various problem-oriented classifications of settlement remains (residential sites, political plaza hierarchies, and territorial divisions). Marked variation is found in the degree of nucleation (interpreted as forced settlement) in the Rosario polity's different subunits, and controlled comparison suggests that such variation relates to differences in the proportional sizes of elite groups and to “backwash” effects between neighboring subunits with unequal degrees of centralization, rather than to population scale, physical environment, or stage reached in a developmental cycle.
