This really depends on the year. Some African women would wear beads, to show their status. The royal women didn't really dress too differently from their citizens, although there may have been a significant difference between patterns on the fabric.

The Declaration of Independence represented a new nation taking on an established power and winning. America was an inspiration for every nation wanting to rule themselves and stop being a colonial outpost. The idea to take on a large powerhouse like Britain, or Spain, as Simon Bolivar was doing, was daunting. The Constitution formed a government that would be set up by and represented the people. All the people would play a role, not just a few people because they have money or other wealth. The Rights of Man and of the Citizen took the foundation laid by the Declaration and the Constitution one more step. The Rights of Man helped establish the rights that each man was born with while also pointing out the rights of the Citizen. It pointed out where the two where similar and where the rights of a citizen differed from those of a man.
