The American Revolution did have an impact on the support for property qualifications for voting. Prior to the Revolution, many of the American colonies had strict property qualifications for voting, which meant that only property-owning white males were eligible to vote. However, during the Revolution, ideas of individual rights, equality, and popular sovereignty gained prominence.

As the Revolution progressed, the principle of "no taxation without representation" became a rallying cry among the American colonists. This principle challenged the notion that only those who owned property should have a say in the political process. The idea that all citizens should have the right to participate in government emerged and gained momentum.

After the Revolution, many states began to revise their state constitutions, and there was a significant shift towards expanding suffrage. Some states abolished property qualifications altogether, while others significantly reduced them. This move reflected a broader belief that voting rights should be extended to a larger portion of the population, irrespective of property ownership.

So, to answer your question, yes, the American Revolution did undermine support for property qualifications for voting. It played a crucial role in shifting the mindset towards more inclusive voting rights and contributed to the democratization of the electoral process in America.
