There were many changes in Western Europe's economy between the fourteenth and fifteenth centuries. The Black Death ended feudalism, strengthened city governments, got trade going again, and made wage work more popular. This helped capitalism get stronger. Bardi and Peruzzi companies were two of the most famous Italian enterprises that started. Guilds controlled the job market and helped people get along with each other. The Hanseatic League illustrates how business groups became more open as citizens engaged in locations like Italy and the Low Countries. At medieval fairs, notably in France and Germany, people used to trade and make new laws. Fair courts made sure that people honored their word and their rights to their property. Lyon's location and financial connections made it an excellent place for banks and money exchanges to do business. These changes made it clear how crucial it is for everyone in the economy to be able to use common institutions. This put Europe on the path to long-term success. The Champagne and Lyon fairs were significant because they helped build up early payment systems and made it easier to trade by setting standards for weights and measurements. These fairs also made Europe a better place to live by bringing people from diverse cultures together to learn from each other.
