In 1428, the Aztecs led a war against their rulers from the city of Azcapotzalco, which had subjugated most of the Valley of Mexico's peoples. The revolt was successful, and the Aztecs became central Mexico's rulers as the Triple Alliance leaders. The alliance was composed of the city-states of Tenochtitlan, Texcoco, and Tlacopan.
