The Inca Culture flourished in the Andean region of South America from the early 15th century until the Spanish conquest in the 16th century. Known for their advanced agricultural techniques, the Incas developed extensive terrace farming and irrigation systems, allowing them to thrive in the challenging mountainous terrain. Inca society was highly organized, with a strong emphasis on community and collective labor. The Sapa Inca, or emperor, was considered a divine figure, and the culture was rich in traditions, including intricate textiles, impressive stone architecture like Machu Picchu, and a complex system of roads that facilitated trade and communication across their vast empire.
