The Aztecs May Have Sent Every Kid to School

Around 500 years ago, one empire appears to have made school mandatory - for basically every kid. Noble, commoner, even the children of the enslaved. And it wasn't in Europe. It was the Mexica.

Their own records point to it: nearly every child was expected to be schooled - regardless of rank or gender. Centuries before that was normal anywhere.

The commoners' school - the telpochcalli

Commoners' kids went to the telpochcalli, the "house of youth" - a neighborhood school for history, craft, and the arts of war.

The nobles' school - the calmecac

Nobles' kids went to the calmecac, the harder school. There they read the painted books, learned the calendar, the stars, law, and rhetoric. It was demanding, disciplined, and it trained the priesthood - so a handful of commoners' sons bound for that path went too.

Girls too - the cuicacalli

And girls were in it too. Both sexes trained in the cuicacalli, the "house of song" - music and dance were part of the curriculum.

The honest hedge

Here's where we stay careful. The evidence is 16th-century - the Codex Mendoza and Bernardino de Sahagún's Florentine Codex - recorded largely by men, and girls' schooling is under-documented. "Compulsory for every child" is an interpretation of those sources, not a headcount. So we say the Mexica appear to have schooled nearly everyone, and call it one of the first - possibly the first - never a flat "first ever." The truth is impressive enough without inflating it.

Possibly the first society on Earth to school everyone. Written down before Columbus's ships were forgotten. Mexican by name. American by history.
