The Raid on Pickawillany is an armed conflict in Ohio history that contributed to the French and Indian War between France and Great Britain, the North American front of the Seven Years' War.
On June 21, 1752, Charles Michel de Langlade, a Métis coureur de bois led 240 French-allied Ottawa and Ojibwa Indians in an attack on the Miami Indian village of Pickawillany. French and British colonists were competing for control of the fur trade in the Ohio Country as part of their overall struggle for dominance in North America. The French also wished to punish Miami chief, Old Briton, for rejecting the French alliance and dealing with the British traders.
The raid resulted in the deaths of Old Briton and at least one English trader. The French and Indians burned the English stockade and storehouse at the trading post, and sent the remaining British traders fleeing back East. Following the attack, the Miami and British abandoned this site. The village of Pickawillany was relocated. The city of Piqua, Ohio developed later near the Miami's second site of this village.
