Story

The narrative of this ancient life

The Late Intermediate Period (LIP) in the Andean region, particularly in areas like San Sebastián, Peru, represents a fascinating era prior to the consolidation of the Inca Empire. This period, which dates from roughly 1000 to 1400 CE, precedes the Incan dominance in the Andean highlands and marks a time of regional development, societal transformation, and significant cultural diversity.

Geographic and Historical Context

San Sebastián is located in the Cusco region, which later became the heart of the Inca Empire. However, 600 years ago, around the year 1400 CE, the region was still experiencing the dynamics of the Late Intermediate Period. This era was marked by the existence of various ethnic groups and polities, each contributing to the intricate socio-political tapestry of the Andes. The collapse of the Wari Empire around 1000 CE left a vacuum that encouraged the emergence of numerous small, independent polities.

Societal Structure and Governance

During the LIP, the Andean highlands, including areas like San Sebastián, were characterized by the presence of small, autonomous communities or chiefdoms. These societies were organized around ayllus, which were kin-based units that controlled land and resources. Each ayllu was often led by a kuraka, a local leader or chief, who managed the redistribution of resources, labor, and established social order.

Economy and Subsistence

The economy in San Sebastián during this period was primarily agrarian. Terracing and irrigation techniques developed during earlier periods were perfected, allowing for successful cultivation in the challenging Andean environment. Key crops included potatoes, maize, quinoa, and various tubers. The people also engaged in pastoral activities, with llamas and alpacas being crucial for transport, wool, and meat.

Trade networks were vital during this period, linking different ecological zones and facilitating the exchange of goods such as coca leaves, salt, textiles, and metal ores. These trade routes often mirrored those that later became established under the Inca Empire.

Material Culture

Art and craftsmanship flourished during the LIP. The people of San Sebastián likely produced elaborate textiles, pottery, and metalwork. Textiles were especially significant, both as functional items and as a form of artistic expression. The designs were often intricate and held cultural or symbolic meanings. Pottery from this period often featured geometric patterns and was used in both everyday life and ceremonial contexts.

Religion and Beliefs

Religious practices in the Late Intermediate Period were diverse, reflecting the variety of cultures in the region. Ancestor worship was a common element, with mummification and reverence of deceased relatives being a significant part of the spiritual life. The landscape, including mountains and rivers, was also imbued with spiritual significance, and these natural features were often personified as deities or spirits.

Conflict and Interaction

While the Late Intermediate Period is noted for its fragmented political landscape, it was also a time of significant interaction, which included both conflict and cooperation. Warfare was not uncommon as groups competed for resources and territory, but alliances and trade partnerships were also essential for survival.

Transition to Incan Hegemony

As the Late Intermediate Period neared its end towards the late 15th century, the emerging Inca Empire began to exert its influence over the region. The consolidation of power by the Incas led to the incorporation of diverse cultural practices and administrative strategies into their empire, building on the foundations laid by societies that thrived during the LIP.

In conclusion, the Late Intermediate Period in regions like San Sebastián, Peru, was marked by vibrant cultural diversity, economic ingenuity, and dynamic social systems that set the stage for the emergence of the Inca Empire. The legacies of this period are reflected in the Inca's later ability to integrate a vast array of peoples and traditions into a cohesive imperial structure.

A Paleogenomic Reconstruction of the Deep Population History of the Andes

Abstract

There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus on the period of the rise and fall of state societies. Today's genetic structure began to develop by 5,800 BP, followed by bi-directional gene flow between the North and South Highlands, and between the Highlands and Coast. We detect minimal admixture among neighboring groups between ∼2,000-500 BP, although we do detect cosmopolitanism (people of diverse ancestries living side-by-side) in the heartlands of the Tiwanaku and Inca polities. We also highlight cases of long-range mobility connecting the Andes to Argentina and the Northwest Andes to the Amazon Basin. VIDEO ABSTRACT.
