Final answer:
The French nobility and royalty would have disagreed with the Declaration of the Rights of Man and Citizen as it opposed their feudal privileges, Divine Right of Kings, and established social order by promoting equality, sovereignty of the nation, and fundamental freedoms.
Step-by-step explanation:
The audience that would have disagreed with the ideas presented in the Declaration of the Rights of Man and Citizen would likely be the French nobility and the royal family, especially King Louis XVI. The declaration embodied Enlightenment ideals which emphasized equality before the law and sovereignty residing with the nation rather than a monarch. Such principles starkly contrasted with the feudal privileges and the Divine Right of Kings that the nobility and monarchy had long enjoyed and depended upon for their social and political power.
The declaration not only signaled a significant shift in the concept of where governing authority should reside - from the king to the nation - but it also introduced concepts such as liberty, property, security, and resistance to oppression. These notions threatened the existing social and political order. For example, it called for taxes to be levied based on one's ability to pay, a notion which would likely displease the aristocracy who were accustomed to tax exemptions.
Additionally, the declaration's assertion of freedom of religion, which would disrupt the traditional and established privilege held by the Catholic Church, was another sticking point for many in the French upper classes.
