From Ohio History Central

Logstown was an American Indian town located roughly eighteen miles south of the Ohio River's headwaters, at modern-day Pittsburgh, Pennsylvania. While the Iroqouis claimed this land, the Lenape (Delaware) and Shawnee lived at Logstown beginning in the 1720s. Members of several other tribes also resided in the community, including the Seneca-Cayuga Indians, the Miami, the Mohawk, and the Wyandot. Because of Logstown's location on the Ohio River, the village became an important trading center for both American Indians 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 American Indian groups in Ohio. An example of this was the attack by the French and their American Indian allies on the Miami town of Pickawillany in 1752. In spite of British interest in the region, Ohio's American Indians found that the British were often  either unable or unwilling to protect their American Indian allies in the region.
