Arrrrr!
In the late 16th century, English ships cruised in the Caribbean and off the coast of Spain, trying to intercept treasure fleets from the Spanish Main. Angel Bard, in spite of being a woman, a colored woman no less, somehow managed to get her hands on a letter of marque from the English crown. Did she disguise the fact that she's a woman? Or is she open about it?
In any case, she and her crew are legally sanctioned to pillage Spanish ships. Who are busy looting the South American indians of their gold. Who were a bunch of blood-thirsty zombie worshipers. (True story) So... history doesn't have any real good guys in it. At least... not on a national level.
