The Incan empire is a Southern American empire dated back to the middle ages and the renaissance. The Incan empire is Centered in a city called Cuzco in Peru. The Incan Empire is one of the most powerful and influential civilizations in human history.

The Inca Empire was located on the western side of South America, stretching from northern Ecuador to central Chile. Its capital of Cusco was located in modern day Peru. It is on the Pacific Coast. Since Inca is on the coast there are some benefits of it. Some benefits are marine resources like fish and water, also a stable trade network and the ability to inherit desert land for farming. This helped with a steady supply of food and resources 

The Inca Empire lasted from approximately c. 1100 to 1533. The Inca fell due to the Spanish Conquistadors and the efforts of indigenous peoples. Combined, these groups were too much for the Incan Empire, and so it fell.

Inventions by the Incan Empire include Quipu, brain surgery, road systems, a messenger system, suspension bridges, terrace farming, freeze drying, designed drainage systems, and developed the calendar. The importance of a few of these inventions are very important like Quipu, road systems, and Terrace Farming. These three inventions were vital to the growth and survival of the Incan Empire. Terrace farming was very vital because this enhanced farming greatly because by putting crops like a staircase because it keeps moisture during droughts and prevents starvation. Quipu is a way of record keeping by utilizing knots tied on string. Quipu is the earliest example of modern day binary code. Road systems were important because it enhaced travel and trade throughout the empiore by making a quicker more efficient path to your destination. Although this invention contributed much to the empire this was also the downfall of the Incan empire because their enimes could easily march in and take over.
