Medieval society was transformed by trade and “burgers.”
In medieval societies, the most widespread result of the revival of trade and urban life was the slow decay of federalisms and its inherent lack of loyalty and the infighting it promoted. Because of the increase in the power of the kings, countrywide courts were established that allowed the spread of “real” justice rather than piecemeal justice handed out by the local Baron. Increases in trade allowed for the creation of a money economy which promoted both the urban life and trade with other countries which increased the flow of ideas into Europe.
