Created on March 21, 1772, from parts
of Lancaster, Cumberland, Berks, Bedford, and Northampton Counties. It probably
was named for the English county of the same name. Sunbury, the county seat was
laid out in 1772, incorporated as a borough on March 24, 1797, and became a city
in 1921. It was named for an English village near London.
The present county area is land acquired by purchases from Indians in 1749 and
1768, but until the formation of Lycoming County in 1795 it included a vast
amount of north central Pennsylvania as far as the Allegheny River. Iroquois,
Delaware, and Shawnee Indians once had sites along the Susquehanna River. Fort
Augusta (at Sunbury) was a key point in frontier defense from 1756 to 1765, but
permanent white settlement began in 1768. Tories and Indians chastised the
population in 1778-1779.
The confluence of the East and West Branches of the Susquehanna made this a
center for gathering lumber and other products to move south. Canals improved
the arrangement. After 1835 rail cars carried anthracite coal to the river and
the county became a mining leader in the 1850s. The older lumber and farming
economy contrasted with the anthracite economy of Mt. Carmel and Shamokin;
railroads rushed in to carry the coal directly to the east. The lumber industry
was enlarged by Ario Pardee. The fourth largest anthracite producing county
until 1952, Northumberland then rose to its present third place. Thomas Edison's
electric lights in Sunbury in 1883 were a technical breakthrough paralleling
Joseph Priestley's scientific discoveries, many of which were made in his
Northumberland home. Shamokin was the center for agriculture in the central
section of the county. Milton became the site of an American Car & Foundry (ACF)
factory in the 1920s. County population has declined in each census since 1930,
when it stood at 128,504. Silk, textiles, and cigars were once major products.
Farms cover 43 percent of the land, and Northumberland is a leading county for
producing chickens, swine, soybeans, and barley.
As reported by the Census Bureau, the county has a total area of 477 square miles (1,236 km2), of which, 460
square miles (1,191 km2) of it is land and 17 square miles (45 km2) of it (3.66%) is water.
