It seemed that the men in the Tudor court wielded all the power. Men made decisions about marriages, land ownership and titles. Although the ultimate power lay with Henry, and it seemed that the men in the Tudor court were always competing over who was closest to Henry at that point in time, and thus more likely to get what they wanted. I think Katherine felt she would make a good man because she was intelligent, was able to stand for what she wanted and was able to diplomatically manage a team, as was shown when she acted as Regent. She was much less guided by her emotions in this area than Henry was, as he was extremely labile.
