Economic life in Transylvania had rebounded quickly after the Mongol invasion.

New farming methods have boosted crop yields.

Craftsmen have formed guilds as artisanry flourishes; gold, silver, and salt mining have expanded; and money-based transactions have replaced barter.

Though townspeople are exempt from feudal obligations, feudalism has expanded and the nobles have stiffened the serfs' obligations.

The serfs resent the higher payments; some have fled the country, while others have become outlaws.

In 1437, Romanian and Hungarian peasants rebel against their feudal masters.

The uprising gathers momentum before the Magyar, German, and Szekler nobles in Transylvania unite forces and, with great effort, successfully quell the revolt.
