Final Answer:
Key achievements of the Inca include the creation of an extensive road network (Qhapaq Ñan), the construction of remarkable stone structures like Machu Picchu, and the establishment of an advanced agricultural system. These achievements were significant as they facilitated communication, trade, and efficient governance, contributing to the success and sustainability of the Inca Empire.
Step-by-step explanation:
The Inca Empire, one of the largest pre-Columbian empires in the Americas, achieved remarkable feats that shaped its success and endurance. The creation of the Qhapaq Ñan, an extensive network of roads spanning over 23,000 miles, was a monumental achievement. These roads connected various regions within the empire, enabling efficient communication, trade, and the movement of troops. The Qhapaq Ñan played a crucial role in the centralized governance of the Inca Empire, allowing rapid mobilization of resources and facilitating the administration of a vast and diverse territory.
The construction of awe-inspiring stone structures, such as Machu Picchu, showcased the Inca's engineering prowess. Machu Picchu served as a royal estate and ceremonial site, displaying advanced architectural techniques and urban planning. The precision with which the Inca cut and fit stones without the use of mortar is a testament to their mastery of construction. These structures not only demonstrated the Inca's ability to manipulate their environment but also served functional and symbolic purposes, reinforcing the empire's cultural and political significance.
The Inca's advanced agricultural system, characterized by terrace farming, helped sustain their population in challenging mountainous terrains. Terrace farming allowed for efficient land use, preventing soil erosion and maximizing agricultural output. This innovation was crucial for supporting the large population of the Inca Empire, contributing to its economic prosperity and resilience. In summary, the Inca's achievements in infrastructure, construction, and agriculture were pivotal to the empire's success, fostering connectivity, governance, and sustainability
