Explanation:

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.

The losing side were tributary provinces that were subject to the dominance of the Aztecs.

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.

The region they controlled comprehends much of South and Central Mexico and states like today Guatemala.
