As one of the Aztec chiefs at the time of the founding of their city was called Tenoch, it is likely that from him was derived the name Tenochtitlan or " Stone-cactus place."
The Aztec name of the city was Tenochtitlan, derived either from Tenoch, one of their priests and leaders, or from tenuch, the Indian name for the " nopal," which is associated with its foundation.
About 1325 they founded on the lake of Tezcuco the permanent settlement of Mexico Tenochtitlan, which is still represented by the capital city, Mexico.
The Aztecs settled there because of the security afforded by its islands and shallow waters - their city, Tenochtitlan, being so completely surrounded by water that a handful of warriors could easily defend its approaches against a greatly superior force.
Mexico-Tenochtitlan, founded about 1325, for many years afterwards probably remained a cluster of huts, and the higher civilization of the country was still to be found, especially among the Acolhuas in Tezcuco.
