History The French-born fur trader James Le Tort may have built a cabin in the area as early as 1720.: 113  During the colonial era, Scots-Irish settlers began to settle in the Cumberland Valley beginning in the early 1730s. The settlement of Carlisle, at the intersection of several Indigenous trails, was designated by the Pennsylvania assembly and the Penn family in 1751 as the seat of Cumberland County (named for the county of the same name in England). American engineer John Armstrong Sr., a surveyor for the Penn family, laid the plan for the settlement of Carlisle in 1751. Armstrong Sr. settled there and fathered John Armstrong Jr. in 1758. They named the settlement after its sister town of the same name in Cumberland, England, and even designed its former jailhouse (which now serve as general government offices in the county) to resemble the Carlisle Citadel.

As a result of conflicts on the frontier with Native American tribes, a stockade was constructed in the settlement to protect against potential attacks in 1753. In 1755, the stockade was transformed into a fort, known as Fort Carlisle or Fort Lowther. In 1757, colonel-commandant John Stanwix—for whom Fort Stanwix in upstate New York was named—–established his headquarters in Carlisle, and was promoted to brigadier general on December 27. During the French and Indian War (the North American theater of the Seven Years' War), the largely successful Forbes Expedition was organized in Carlisle in 1758; Henry Bouquet also organized a military expedition from the settlement in 1763 during Pontiac's War.
