Did you know?
With a metropolitan area of more than 20 million people, Mexico City could be called the world's second or third most populous city. And the nearby Aztec city of Tenochtitlán was one of the largest cities in the world even when Hernán Cortés arrived there in 1519. But by the time Cortés conquered the city in 1521 it wasn't nearly so populous, since European diseases had greatly reduced the population. Avoid confusing populous and populace, which are pronounced exactly the same.
