Review Questions

  • How did Incan agricultural innovations contribute to their ability to maintain such a vast empire?
    • Incan agricultural innovations like terrace farming and advanced irrigation systems played a crucial role in supporting their large population. By adapting to the mountainous terrain of the Andes, they maximized arable land and increased crop yields. This agricultural surplus enabled them to sustain a powerful centralized government and support their extensive military campaigns, which were essential for maintaining control over their vast territory.

    • Machu Picchu is significant as it represents the pinnacle of Incan architectural achievement and reflects their advanced engineering skills. The site serves as a testament to their ability to build impressive structures that harmonize with their natural surroundings. Additionally, Machu Picchu provides insight into Incan societal structure, religious practices, and their connection to the surrounding environment, making it a key site for understanding the Incan civilization as a whole.
  • Evaluate how Atahualpa's capture by Spanish conquistadors influenced the outcome of the Inca Empire's struggle against European colonization.
    • Atahualpa's capture marked a pivotal moment in the struggle of the Inca Empire against Spanish colonization. His execution not only eliminated a key political leader but also caused widespread disarray within Incan society, undermining morale and resistance efforts. The subsequent Spanish conquest exploited this chaos, allowing conquistadors like Francisco Pizarro to swiftly seize control over much of the Inca territory. This event highlights how individual leadership plays a critical role in determining historical outcomes during periods of conflict.
