It is a township rich in history, dating back to early 19th-century settlement. Officially incorporated on December 26, 1878, it evolved from an agricultural and timber-based economy to an industrial hub, supported by its abundant natural resources—including coal, salt, timber, natural gas, and sand—and its strategic location along the Allegheny and Kiskiminetas Rivers. These rivers not only fostered trade and transportation but also enabled Gilpin’s transformation into a manufacturing center. The township includes various communities—Bagdad, Johnetta, Schenley, Georgetown, Banfield, Forks Church, Aladdin, and Maher Heights—each contributing uniquely to its development and legacy. As of the 2020 Census, its population was 2,411.
