Income

It is estimated that the per capita income of northern Italy nearly tripled from the 11th century to the 15th century.

Literacy and numeracy

Communes

During the 11th century in northern Italy a new political and social structure emerged: the city-state or commune. The civic culture which arose from this '' urbs'' was remarkable. In some places where communes arose (e.g. Britain and France), they were absorbed by the monarchical state as it emerged. They survived in northern and central Italy as in a handful of other regions throughout Europe to become independent and powerful city-states. In Italy the breakaway from their feudal overlords occurred in the late 12th century and 13th century, during the
