The growth of trade and industry weakened feudalism by creating a new class of wealthy merchants and entrepreneurs who were able to accumulate wealth independently of the feudal system. This allowed them to challenge the power and authority of the feudal lords and kings, leading to a shift in economic and social power away from the feudal system. Additionally, the increased availability of goods and services through trade and industry undermined the self-sufficiency and reliance on feudal obligations that had previously characterized feudal society.
