Jan. 28 (UPI) -- A trove of private papers belonging to British King George III show his frustration at losing the American colonies and his willingness to abdicate in the midst of a political storm.
Dubbed the "mad king" for the medical problems he suffered later in his reign, George III is Britain's longest serving king, ruling from 1760 to 1820. Fairly early in his reign, colonists in America declared their independence in 1776, triggering the Revolutionary War.
