Although generally good natured, if provoked, Queen Elizabeth could display a show of right royal anger ! Once she threw her slipper at  Walsingham, and if really angry,  would threaten to send people to the Tower. Those who married without her consent, could well find themselves under lock and key.  Her bark was usually worse than her bite, however, and although Elizabeth has earned the reputation of "The Ice Queen", this is wholly undeserving, as even her contemporaries noted that the anger of other monarchs was far more frightening than the anger of their Queen.   Elizabeth usually only got angry if there was good cause.
