This powder horn, engraved with a walled city, flags, and a crown symbol, commemorates the July 7, 1763, British evacuation of Havana on the island of Cuba, marking the end of the Seven Years' War (1756-1763). Sparked by a May 1754 skirmish involving a 22-year-old George Washington, the Seven Years' War became a global conflict with fighting in North America, Europe, Asia, Africa, and the Caribbean. Most American colonists felt intense pride as members of the great British Empire that had defeated France and Spain, but British efforts to raise revenue and tighten control in the colonies soon turned joy into despair.
