Considered the "great authority on all that concerns the Anjou marriage" (DNB), The Compleat Ambassador chronicles the marriage negotiations between Queen Elizabeth I of England and Prince Francis Anjou of France from 1570-1581. Twice her suitor's age, Elizabeth was said to have ended the engagement due to fears of attempting to bear a child, though it is more commonly accepted that she did so in order to preserve England's sovereignty, a decision which ultimately led to her historical reputation as the "Virgin Queen."
