Cumberland County, Pennsylvania, is marking its 276th anniversary today. The county was formed on January 27, 1750, from Lancaster County.
Originally, Cumberland County extended to Pennsylvania’s western limits. The county seat, Carlisle, was founded in 1751. Cumberland County played a key role in westward migration due to its location along major roadways.
Today’s anniversary recognizes the county’s founding and its historical significance in the development of the region.
