The American Revolution
Lord North (1732-1792), originally Frederick North, held many elite British offices before becoming Prime Minister in 1770. North maintained that post throughout the buildup to the Revolution and the battles that followed, until the decisive British defeat at Yorktown in 1781, after which he resigned his post.
North extended Parliament's version of an "olive branch" in early 1775, when the English government offered to desist from taxing any colony that made adequate provisions to support its civil and military government. But then Parliament proceeded to pass laws restraining trade and fisheries in New England, and later in all the colonies. North's "olive branch" offer did not succeed and the first shots of the war were fired a few months later.
