Shirleysburg was originally the site of, and takes its name from, Fort Shirley, a French and Indian War fort. In 1754, the Oneida chief Monacatoocha (Scarouady) led about 200 pro-British Native Americans (Iroquois, Lenape, and Shawnee) from their village of Logstown on the western frontier, to take refuge at George Croghan's trading post. That same year, Croghan built a stockaded blockhouse known as Croghan's Fort. Following General Edward Braddock's defeat in July 1755, Governor Robert Hunter Morris ordered it renamed Fort Shirley and had several other forts built in a defensive line, to protect settlers from Native American attacks. The fort was abandoned in late 1756 because it was considered too difficult to defend.
