I blogged once about how one of the things I value in a protagonist is standing outside the norms and structures of societal power in some way. It gives them more incentive to see the cracks in the system. The fact that all my protagonists are women in early 19th century Europe gives them a head start on that outsider status, though there were certainly plenty of women who didn't view themselves in that way. Ones who enjoyed and accepted the place that gave them in the world.
