Previously, the Chimú empire was thought to have dominated the north coast of Peru during the Late Intermediate period, virtually to the exclusion of other polities. However, new research on sites from this period has not only changed perspectives on the Chimú, but also shed light on two other important coastal polities: the Lambayeque/Sicán and the Casma, providing insights with the potential to reshape our understanding of the development of urbanism and the Andean state. This article presents a critical summary of recent literature, fieldwork, and discoveries. Analyses of these new data address a wide range of topics that can be loosely grouped into four major areas: complexity in political organization and the geopolitical landscape, variations in the urban environment, the intensification of trade and exchange, and dynamic expressions of religion and ideology. The latest interpretation of the north coast Late Intermediate period is a story of three major, competing polities that were eventually subsumed under one.

秘鲁北部史前晚期海岸政体的新研究

以前，人们认为Chimú帝国在中期中后期统治了秘鲁的北海岸，几乎排除了其他政体。但是，这一时期的新遗址研究不仅改变了人们对奇穆（Chimú）的看法，而且揭示了另外两个重要的沿海政体：兰巴耶克（Lambayeque）/西坎（Sicán）和卡斯马（Casma）。城市主义和安第斯国家。本文提供了最新文献，实地考察和发现的重要总结。对这些新数据的分析涉及广泛的主题，可以将其大致分为四个主要领域：政治组织和地缘政治格局的复杂性，城市环境的变化，贸易和交流的加剧，宗教和意识形态的动态表达。对北海岸后期中期的最新解释是关于三个主要竞争政体的故事，这些政体最终被归为一个。
