What was the greatest of the Incas many achievements? Explain your answer.

One of the greatest achievements of the Incas was their extensive road network known as the Inca road system. This network consisted of over 25,000 miles of roads that connected the vast Inca Empire, stretching from modern-day Ecuador in the north to Chile in the south.

The Inca road system was a remarkable engineering feat, as it included bridges, tunnels, and intricate stone staircases that traversed through the rugged Andes mountains and diverse terrains. These roads were crucial for facilitating communication, trade, and the movement of armies throughout the empire. In addition, the roads also played a key role in the centralized governance of the Inca Empire, allowing for efficient transportation of goods and resources between different regions.

Overall, the Inca road system was a testament to the ingenuity and advanced engineering skills of the Inca civilization. It not only enabled the Inca Empire to flourish and expand but also left a lasting legacy in the form of a well-connected network that facilitated economic, social, and political interactions within the empire.
