Anne Boleyn gets my vote.
As some earlier posts mentioned, Henry's pursuit of her bordered on what, in modern terms, we would call sexual harassment. I think Anne was pressured into a relationship she felt was unsafe to refuse. And I think much of her subsequent demanding and self-aggrandizing behavior was anchored in her conviction that, if she was going to have to accept the importunities of a man she did not love, she at least had a right to get something from the bargain.
And what a foul bargain it turned out to be, after all. Her survival came to depend on something over which she had no control -- having a male child. And the cost she paid for failing was to go to her death, knowing her brother was suffering the same fate under the same false calumny of incest, and probably assuming her daughter had little chance of ultimately surviving.
