The Triple Alliance encompasses the military and political alliance among Tenochtitlan, Texcoco and Tlacopan.
Lasting from 1428 until 1521 , the Triple Alliance was formed by the winning sides of a long civil war between Aztecs and former opponents.
<em>The losing side were tributary provinces that were subject to the dominance of the Aztecs. </em>
<em>The Aztecs based their power on a Emperor that had priests and army generals and officers. Eventually they had predominant role over the other city states.</em>
