soon as he began to patronise her and hint that she owed her coming crown to the intervention and support of Philip, she stopped him at once, and said that she would owe it only to22 her people. She was equally firm and queenly when Feria thus early hinted at her marriage with her Spanish brother-in-law before the breath was out of Mary’s body, and showed a firm determination to hold her own and resist all attempts to place her under the tutelage of Philip. A week afterwards the Queen d, and then began the keen contest of wits around the matrimonial sibilities of Elizabeth, which ended in the of modern England.
