What is an accomplishment of the incas?

Answer 1

One of the most significant accomplishments of the Incas was the construction of an extensive and sophisticated road system, known as the Qhapaq Ñan, which spanned over 25,000 miles across diverse terrains. This network facilitated communication, trade, and the efficient movement of their military and resources throughout the vast Inca Empire. Additionally, the Incas excelled in agricultural innovation, developing terraced farming techniques that maximized arable land in the Andean mountains. Their achievements in architecture, such as the iconic Machu Picchu, also demonstrate their advanced engineering skills.
