Northumberland, Administrative division in Pennsylvania, United States.
Northumberland County encompasses 478 square miles of land with mountains in the south and north, including Mahanoy Mountain and Big Mountain near Susquehanna River.
The county emerged in 1772 from parts of Lancaster, Berks, Bedford, Cumberland, and Northampton Counties, named after the northern English county of Northumberland.
The Akhrakouaeronon people, part of the Susquehannock tribe, maintained settlements in this region before European colonization began in the eighteenth century.
The county seat of Sunbury serves as the central administrative hub, managing public services and governmental operations for over 91,000 residents across the territory.
Joseph Priestley, the prominent chemist who discovered oxygen, established his residence along the Susquehanna River in 1796 after leaving England.
