Through the steady taxation of Edward III's reign, parliament – and in particular the Commons – gained political influence. A consensus emerged that in order for a tax to be just, the king had to prove its necessity, it had to be granted by the community of the realm, and it had to be to the benefit of that community. In addition to imposing taxes, parliament would also present petitions for redress of grievances to the king, most often concerning misgovernment by royal officials. This way the system was beneficial for both parties. Through this process the commons, and the community they represented, became increasingly politically aware, and the foundation was laid for the particular English brand of constitutional monarchy.
