Indigenous societies in Latin America were diverse and complex before European contact. The Maya, Aztec, and Inca developed advanced political systems, trade networks, and urban centers. They practiced polytheistic religions and created sophisticated art and agriculture. European explorers arrived in the late 15th century, seeking wealth and religious conversion. Spanish conquistadors, aided by military superiority and disease, conquered the Aztec and Inca Empires. This led to colonial administrations and the imposition of European systems on indigenous societies.
