Which civilization built the Chichen Itza in Mexico?

Chichen Itza was a large pre-Columbian city built by the Maya people of the Terminal Classic period. The archaeological site is located in Tinúm Municipality, Yucatán State, Mexico.

It was a major focal point in the Northern Maya Lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c. AD 800–900) and into the early portion of the Post-classic period (c. AD 900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the ''Puuc'' and ''Chenes'' styles of the Northern Maya lowlands.

Chichen Itza was one of the largest Maya cities and it was likely to have been one of the mythical great cities referred to in later Mesoamerican literature. The city may have had the most diverse population in the Maya world, a factor that could have contributed to the variety of architectural styles at the site.

The Maya name "Chichen Itza" means "At the mouth of the well of the Itza". This derives from ''chi'', meaning "mouth" or "edge", and "chʼen", meaning "well". ''Itza'' is the name of an ethnic-lineage group that gained political and economic dominance of the northern peninsula. One possible translation for ''Itza'' is "enchanter (or enchantment) of the water".
