Widening Social Gulf
l By the 16th century the seven original calpulli had
expanded from kinship groups to become
residential groupings including neighbors, allies,
and dependents.
l The calpulli performed vital local functions in
distributing land and labor and maintaining
temples and schools.
l During wars they organized military units.
l Calpulli were governed by councils of family
heads, but all families were not equal.
l During Aztec expansion a class of nobility (pipiltin)
had emerged from privileged families in the most
distinguished calpulli.
