The Mexica (Nahuatl: Mēxihcah, the singular is Mēxihcatl or Mexicas — were an indigenous people of the Valley of Mexico, known today as the rulers of the Aztec empire.
The Mexica were a Nahua people who founded their two cities Tenochtitlan and Tlatelolco on raised islets in Lake Texcoco around AD 1200. After the rise of the Aztec Triple Alliance, the Tenochca Mexica (that is, the inhabitants of Tenochtitlan), assumed a senior position over their two allied cities — Texcoco and Tlacopan.
The Mexica are eponymous of the placename Mexico Mēxihco. This refers to the interconnected settlements in the valley which became the site of what is now Mexico City, which held natural, geographical, and population advantages as the metropolitan center of the region of the future Mexican state. This area was expanded upon in the wake of the Spanish conquest and administered from the former Aztec capital as New Spain.
Like many of the peoples around them, the Mexica spoke Nahuatl. The form of Nahuatl used in the 16th century, when it began to be written in the alphabet brought by the Spanish, is known as Classical Nahuatl. Nahuatl is still spoken today by over 1.5 million people.
