From 1690, William was often away from England, at first fighting Jacobites in Ireland. While her husband was away, Mary took care of the government. She was a firm ruler, and ordered her own uncle, Henry Hyde, 2nd Earl of Clarendon, to go to prison for trying to put James II back onto the throne. In 1692, she fired and put John Churchill, 1st Duke of Marlborough, in prison for similar reasons. This made her much less popular. It also damaged her relationship with her sister, Anne. Anne had been strongly influenced by Churchill's wife, Sarah. She appeared at court with Sarah and supported Churchill, which made Mary very angry. She demanded that Anne make Sarah go away. Mary did not visit Anne during her pregnancy after that. After the baby was born, Mary did visit Anne, but she spent her time berating Anne for her friendship with Sarah. The sisters never saw each other again.
