[[There were occasional instances in which popular uprisings were led by nobles. It depended on the area. Places like Italy and Flanders, where the nobles, at least the local ones, were becoming economically integrated with the bourgeois money makers, were more prone to this sort of thing. Then there were guys who claimed to be nobles, or wanted to be, and couldn't establish their rights, which made them prime leaders for local uprisings. Noble powers were constantly evolving and changing. The king would limit a power or privilege in one way, and the nobles would extract a different concession. Local towns would buy rights from their lords, trading marks for obligations, and so forth. It was by no means a stable political or social environment, and rebellion was a constant threat.
