Final answer:
The American Revolution and the French Revolution were both significantly influenced by the interests of the middle class, leading to major revolts against monarchical control and the mercantilist system.
Step-by-step explanation:
The two revolutions in which the growing power and anti-mercantilist interests of the middle class were a major cause of revolt are the American Revolution and the French Revolution. In the American Revolution, colonists resisted British efforts to consolidate control, which included taxation without representation and arbitrary monarchical power. This expanded into a full-blown fight for independence. The French Revolution was similarly spurred by a middle class that was growing in wealth and education but was excluded from political power, mingled with resentment from poor harvests and almost-bankrupt crown, culminating in an uprising that led to the end of monarchical rule and the establishment of a republican government. The two revolutions in which the growing power and anti-mercantilist interests of the middle class were major causes of revolt are the American Revolution and the French Revolution.
In the American Revolution, colonists rejected arbitrary monarchical power and taxation, demanding national independence. The French Revolution, on the other hand, was a rejection of traditional royal privileges and the establishment of a new political model. In both cases, the growing middle class, resentful of being excluded from political power, played a significant role in driving the revolutions.
