The Inca civilization was one of the most vital societies in South America in terms of its cultural influence and legacy. Around from 1438 to 1533, the Incas began as a small tribe who steadily grew in power to conquer people down the coast from today's Colombia to Argentina. They are remembered to this day for their architecture, agricultural techniques, communication, and record-keeping.
