The Story
Mercer County was established in 1800 from Allegheny County when this corner of western Pennsylvania was still thinly settled frontier, home to just over three thousand people. It honors General Hugh Mercer, the Revolutionary War officer mortally wounded at the Battle of Princeton in 1777. Rich in iron ore and coal, the region became an early center of industry, and the county seat of Mercer was incorporated in 1814.
Why it matters
The county's story links Revolutionary sacrifice to the westward push of settlement and the mineral wealth that would fuel Pennsylvania's industrial rise.

Meadville
Meadville, PA
In 1788, David Mead and a small band of settlers pushed west from Pennsylvania's Wyoming Valley to plant a settlement on French Creek, in country only recently opened to American pioneers. The town they founded grew quickly enough to become the seat of Crawford County by 1800, and it went on to leave two very different marks on the nation: in 1842 it staged what is remembered as the first direct primary election in the United States, and decades later it became a cradle of the 'hookless fastener' โ the humble zipper โ turning a frontier outpost into an unlikely engine of American invention.
Crawford County
Meadville, PA ยท est. 1982
Formed from Allegheny County in 1800 and named for Colonel William Crawford, Crawford County grew up around Meadville, which in 1788 became the first permanent settlement in northwestern Pennsylvania. The county proved a seedbed of American firsts: the nation's first direct primary election was held here in 1842, and it became a cradle of both the oil industry and the modern zipper. Meadville anchored settlement in a corner of the state that was still wild frontier when the town was founded.
Brady's Bend Works
Bradys Bend Township, PA
For a third of the nineteenth century, the bend of the Allegheny River at Brady's Bend roared with the work of one of America's great early ironworks. Founded in 1839 as the Great Western and later reorganized as the Brady's Bend Iron Company, it grew into one of the largest iron operations of its era, drawing on the coal and iron ore of western Pennsylvania. Most remarkably, it became the first works to roll iron rails on the western side of the Allegheny Mountains โ feeding the very railroads that were then stitching the growing nation together. When it closed in 1873, it left behind a company town and the memory of a place where American heavy industry came of age beyond the eastern seaboard.
Clarion County
Clarion, PA
When Pennsylvania carved Clarion County from Armstrong and Venango in 1839, it named the new territory for the river whose clear, bell-like current early travelers likened to a distant clarion horn. The hills here proved rich in the raw materials of the young industrial age: charcoal-fired iron furnaces sprang up across the county, while abundant coal seams and vast timber stands fed a lumbering trade that floated logs downstream to market. The seat town of Clarion took shape quickly, incorporating as a borough by 1841 as the county organized itself around courthouse and commerce.
