Origins and Historical Expansion of the Empire

  • Migratory Origins: Historically, the Incas appear to be groups of migrants originating from the Lake Titicaca region. They arrived in the Valley of Cuzco approximately in the XIIIXIII century AD (dCdC).

  • Foundational Legend: The Incas explained their origins through a sacred myth. According to this legend, Cuzco was the site designated for Mama Ocllo and Manco Capac, who were both siblings and spouses. They were sent to Earth by their father, the Sun (Inti), to establish order in the lives of men.

    • Tupac Inca Yupanqui (14711471 to 14931493): The son of Pachacutec. Under his rule, the empire reached its maximum splendor. Significant conquests during this period included the entirety of the Andean Altiplano and the northern territories of Chile and Argentina.

    • Huayna Capac: The successor of Tupac Inca Yupanqui who achieved the greatest territorial extension of the empire.

    • Moche

    • Nazca

    • Tiahuanaco

    • Huari

    • Chimú

Inca Social Structure and Governance

  • Theocratic Governance: The Inca Empire was strictly dominated by a sacred and inviolable theocracy. While the Incas imposed their military might upon conquered peoples and mandated the worship of Inti (the Sun), they often respected the existing cultures of those peoples.

  • The Role of the Inca: As the highest political and religious authority, the Inca was considered the direct descendant or "Son of the Sun."

  • Aristocracy and Nobility:

    • Orejones: A select aristocracy that assisted the Inca in governing. They were named for the large ornaments they wore which deformed their ears.

    • Military Nobility: Generals and high-ranking officers were also considered part of the noble class.

    • Kurakas (Curacas): Positioned below the aristocracy, these individuals served as lords or local leaders.

  • Privileged and Specialized Classes:

    • Sacerdotal Class: Included the Willaq Uma (the sacred head or high priest), the Aqllas (the chosen ones or "escogidas"), and secondary priests.

  • The Common People: The base of the social pyramid consisted of the general population, divided into:

    • Llacta Runa: The native or original inhabitants.

    • Mitimaes: Individuals or groups transplanted from other regions or newly conquered territories to different parts of the empire.

  • Yanacunas (Yanaconas): A class outside the standard social tiers, literally defined as slaves.

  • Social Principles: The entire society functioned based on the binary principles of Reciprocity and Redistribution.

Economic Framework and Property Organization

  • Agricultural Base: Agriculture was the fundamental pillar of subsistence. The strong central power directed collective labor (tribute) into massive infrastructure projects:

    • Canals, Terraces (Andenes), and Aqueducts: These were multiplied continuously to increase arable land.

    • Primary Crops: Maize (corn), potatoes, and quinoa.

    • Techniques: Use of fertilizers and the Taclla (a type of foot plow used to turn soil).

  • Resource Management:

    • Camelids: Essential resources for the State of Tahuantinsuyu, providing both meat and fiber (wool).

    • Mining: Organized exploitation of mines for metals including gold, copper, silver, bronze, tin, and lead.

  • Trade and Crafts:

    • Commerce: Conducted through small-scale barter (trueque).

    • Artisanship: Production of textile masterpieces and high-quality ceramics.

  • State Property and Tripartite Land Division:

    • The State owned the land, herds of llamas, and mines. Most land was worked communally.

    • The State protected the population from hunger, exploitation, and hardship, but in exchange, individuals were highly regulated; leaving the community without permission was forbidden.

    • The Tripartite Division: Land was divided into three portions for the benefit of:

      1. The State.

      2. The Church (Sacerdotal class).

      3. The People.

Religious Beliefs and Deities

  • The State Church: In a unique arrangement for indigenous America, the Inca State supported the Church. The primary goals of the religious institution were to increase food reserves and heal the sick.

  • The Pantheon of Deities:

    • Viracocha: The supreme god, immortal creator of all things in the universe and on earth.

    • Inti (The Sun): The principal god and protector of the royal dynasty. He was depicted with a human face from which rays emanated. His primary temple was the Coricancha.

    • Illapa (God of Thunder): Ranked next in importance; associated with rain water, which was believed to come from a celestial source.

    • Manaquilla (The Moon): The wife of the Sun.

    • Venus: A very important planet believed to watch over and care for humans.

    • The Pleiades: A star cluster believed to protect seeds.

    • Pachamama (Earth Goddess): Crucial for agricultural success.

    • Mamacocha (Sea Goddess): Crucial for fishing.

  • Sacred Sites:

    • Huacas: Altars located along roadsides where offerings were placed.

    • Apachetas: Stone sanctuaries used specifically for prayer.

Systems of Accounting and Education

  • Accounting (The Quipu):

    • The Quipu-Kamayoc was the official responsible for performing censuses and maintaining administrative records.

    • The tool used was the Quipu, a system of knotted strings used to base all imperial decisions on statistical data.

  • Educational System:

    • Education was strictly reserved for the nobility.

    • The Schools: Located in the city of Cuzco.

    • Curriculum: Arithmetic, astronomy, religious precepts, political/historical knowledge, and the technical use of quipus.

    • Amautas: The teachers or sages responsible for imparting this knowledge.

    • Popular Education: The general public had no access to systematic schooling. However, for political reasons, the State ensured all inhabitants learned Quechua, the official language of the empire.

Philosophy of Governance and Tools of Imperial Control

  • The Andean Worldview: Governance in the Tahuantinsuyu was based on the principle of the general good. A central tenet was: "To govern is to make everyone work with joy for the benefit of the community." Personal accumulation of wealth at the expense of the Ayllu (community unit) did not exist.

  • Essential Pillars for Maintaining the Empire:

    • The division into 4 Suyos.

    • The Ayllú (communal social unit).

    • The Mita (mandatory labor tax).

    • The Ejército (Army).

    • Quechua (unified language).

    • Caminos (extensive road network).

    • Quipú (administrative/accounting records).

    • Inti (state religion/Sun worship).

    • Pukará (fortifications).

    • Tambos (rest/supply stops).

    • Chasquis (messengers/runners).

    • Mitimaes (resettled populations used for stability).

Architecture and the Road System

  • Legacy: Architecture remains the most significant material legacy of the Incas.

  • The Great Road Network (Los Caminos): The vast empire was unified by roads that integrated several elements:

    • Tambos: Inns or storage structures for travelers and officials.

    • Pukarás: Defensive fortresses.

    • Puentes (Bridges): Critical for crossing the varied Andean terrain.
