Differences between the Aztecs, Mayans and Incas include their location and language system. The Aztecs lived in what is now central Mexico, while the Mayas lived in southern Mexico and the Inca civilization was focused around Chile and Peru. Both the Aztecs and the Mayans developed a writing system for their language, while the Incas did not.
The Aztecs, Mayans and Incas were three highly developed ancient civilizations. The first Mayan settlements were founded around 1800 B.C., with the great Mayan cities being built starting in 250 A.D. The Aztec and Incan civilizations were founded later, in approximately 1325 A.D. and 1200 A.D., respectively.
The Incan civilization covered a larger area of land, extending 2,500 miles from northern South America along the Pacific coast. Each established laws and a government. The Aztec and Incan government centered around a capital: Tenochtitlan for the Aztecs, Cuzco for the Incas and Tikal for the Incas. The Mayan government created several powerful city-states, such as Tikal.
The Aztec and the Incan civilizations were conquered by the Spanish in the 16th century and their cities were largely destroyed. The Mayans were also conquered by the Spanish during that time, however, much of the civilization had collapsed before then.
