Spanish colonial pueblos and villas in North America
Spanish colonial authorities in North America established misiones (churches with attached farms), presidios (military forts), and villa or pueblos (civilian settlements with residences, retail businesses, agricultural markets, etc.). Official pueblo establishments (as opposed to those that developed organically) were granted four square Spanish leagues of land and were required to be sited at least five Spanish leagues away from any other pueblo.
