King George III Royal Military Appointment Signed.

George III was King of Great Britain and King of Ireland from 1760 until the union of the two countries in 1801, after which he was King of the United Kingdom of Great Britain and Ireland until his death in 1820. His life and reign, which were longer than those of any of his predecessors, were marked by a series of military conflicts involving his kingdoms including the defeat of France in the Seven Years' War early in his reign which made Britain the dominant power in North American and India. Many of Britain's colonies were soon lost, however, in the American Revolutionary War. Further wars against revolutionary and Napoleonic France from 1793 concluded in the defeat of Napoleon at the Battle of Waterloo in 1815.
