How did earlier South American civilizations influence the Inca empire?

Earlier South American civilizations, such as the Moche, Nazca, and Tiwanaku, laid foundational cultural, agricultural, and architectural practices that significantly influenced the Inca Empire. These civilizations developed advanced agricultural techniques, such as terrace farming and irrigation systems, which the Incas adapted and expanded upon. Additionally, artistic styles, religious beliefs, and trade networks established by these earlier societies were integrated into Inca culture, helping the empire to unify diverse groups and enhance its own identity. The Incas also inherited and refined architectural techniques, leading to their impressive stone structures and road systems.
