Itzcoatl (Classical Nahuatl: Itzcōhuātl [it͡sˈkoːwaːt͡ɬ], "Obsidian Serpent", ⓘ) (c. 1380–1440) was the fourth king of Tenochtitlan, and the founder of the Aztec Empire, ruling from 1427 to 1440. Under Itzcoatl the Mexica of Tenochtitlan threw off the domination of the Tepanecs and established the Triple Alliance (Aztec Empire) together with the other city-states Tetzcoco and Tlacopan.
