In The Middle Ages, What Ways Have Kings-by-Marriage Stolen Power From Their Royal-by-Blood Queens?

Could be from any time in the Medieval period or Renaissance. I'm writing a story in which a man of noble birth steals power from his royal wife after becoming King. In the scenario, the Queen only became so after marriage, if that matters.

Have there been examples in history of Kings turning a Queen's own court against her? Him making them listen to his word over hers? How was she treated? Could she have regained their favor after his death?
