From Ohio History Central
Logstown was an Indian town located roughly eighteen miles south of the Ohio River's headwaters, at modern-day Pittsburgh, Pennsylvania. While the Iroqouis Indians claimed this land, members of the Delaware and Shawnee Indians lived at Logstown beginning in the 1720s. Members of several other tribes also resided in the community, including the Mingo Indians, the Miami Indians, the Mohawk Indians, and the Wyandot Indians. Because of Logstown's location on the Ohio River, the village became an important trading center for both natives and Europeans.
When Celeron de Bienville made his expedition laying claim to the Ohio Country in 1749, he reported back to the French government that Logstown had become an important trading post for the British. It was concern such as this that led the French to try to reassert their authority over the natives in Ohio. An example of this was the attack by the French and their Indian allies on the Miami Indian town of Pickawillany in 1752. In spite of British interest in the region, the natives found that the British were often either unable or unwilling to protect their Indian allies in the region.
