"marry her willy-nilly to Emmanuel Philibert"

Emmanuel Philibert, Prince of Piedmont and Duke of Savoy (1528-1580), Catholic and Spaniard, was the suitor chosen by Mary's husband Philip for Elizabeth.  As far as Philip was concerned, such a marriage would be ideal.  As his own marriage to Mary seemed increasingly to be a failure from the point of view of securing the succession to the English throne for Spain, the next best thing would be to secure it through the Duke of Savoy.  Philip exerted pressure on Mary to command her sister to agree to the marriage, but in this Mary proved to be an unlikely ally for Elizabeth and the marriage did not go ahead.
