Lehigh County (Pennsylvania Dutch: Lechaa Kaundi) is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the county's population was 374,557.[1] Its county seat is Allentown, the state's third-largest city after Philadelphia and Pittsburgh.[2]

Lehigh County and Northampton County to its east combine to form the Lehigh Valley region of eastern Pennsylvania. Lehigh County is one of the fastest-growing counties in Pennsylvania and the more highly populated of the two counties.[3][4] Both counties are part of the Philadelphia television market, the fourth-largest television market in the nation.

The county is named for the Lehigh River, a 109-mile-long (175 km) tributary of the Delaware River, which flows through Lehigh County. The Lehigh River served a vital role in the county's development by offering a transportation and trading route for its mining products, including iron, manganese, limestone, and ultimately manufactured steel products.

Lehigh County falls geographically between two Pennsylvania Appalachian mountain ridges, Blue Mountain to the county's north and South Mountain to its south. Lehigh County borders Montgomery County to its south, Bucks County to its southeast, Northampton County to its east, Carbon County to its north, Schuylkill County to its northwest, and Berks County to its southwest.

The county is located 61 miles (98 km) northwest of Philadelphia and 99 miles (159 km) west of New York City.

History

Shelter House in Emmaus, constructed in 1734 by Pennsylvania German settlers, is believed to be the oldest continuously occupied building structure in both Lehigh County and the Lehigh Valley and among the oldest still-standing building structures in Pennsylvania.[5][6]
The Soldiers and Sailors Monument, erected in 1899 at 7th and Hamilton streets in Center City Allentown, honors men from Allentown and its suburbs killed in their volunteer service in the 47th Pennsylvania Infantry Regiment and other Union Army units during the American Civil War.

Settlement and founding

Lehigh County was first settled around 1730 and was formed in 1812 when Northampton County was divided into two counties. The county is named after the Lehigh River, a 109-mile-long (175 km) river that runs through the county and whose name is derived from the Lenape Indian term Lechauweki or Lechauwekink, meaning "where there are forks."[7] Shelter House, constructed in Emmaus in 1734 by Pennsylvania German settlers, is the oldest continuously occupied structure in both Lehigh County and Lehigh Valley and among the oldest still-standing building structures in the U.S. state of Pennsylvania.[5][6]

American Revolution

Further information: Pennsylvania in the American Revolution

Some of the first resistance to British colonialism, which led ultimately to the American Revolutionary War, began in present-day Lehigh County. On December 21, 1774, patriots in the area formed one of the colonies' first Committee of Observations. Following the Declaration of Independence, patriot militas pressured Tories out of Allentown and the surrounding area, and the colonial government in the area began to break down.

After Washington and the Continental Army were defeated at the Battle of Brandywine on September 11, 1777, the revolutionary capital of Philadelphia was left defenseless and Pennsylvania's Supreme Executive Council ordered that eleven Philadelphia bells, including the Liberty Bell (then known as the State House Bell), be taken down and moved to present day Allentown (then called Northampton Towne) and hidden in the basement of Zion Reformed Church on present day West Hamilton Street to protect them from being melted down by the British Army for use as munitions.

Industrial Revolution

The opening of the Lehigh Canal beginning in 1827 transformed Allentown and Lehigh County from a rural agricultural area dominated by German-speaking people into an urbanized industrialized area and expanded the city's commercial and industrial capacity greatly. With this, Lehigh County underwent significant industrialization, ultimately becoming a major 20th century center for heavy industry and manufacturing and one of several hubs for the Industrial Revolution.

American Civil War

Following the Union Army's defeat at the Battle of Fort Sumter and Lincoln's April 15, 1861 proclamation calling for state militia to provide 75,000 volunteer troops to defend the nation's capital of Washington, D.C., Allentown deployed the Allen Infantry, also known as the Allen Guards and composed of volunteers from Allentown and its surrounding suburbs. The unit mustered in for duty on April 18, 1861. As the Civil War progressed, multiple Union Army units were drawn from Lehigh County, including roughly seventy percent of the 47th Pennsylvania Infantry Regiment.

On October 19, 1899, a monument in honor of the Lehigh County men killed in their volunteer service to preservation of the Union, the Soldiers and Sailors Monument, was erected at Seventh and Hamilton streets in Center City Allentown, where it still stands.[8]

Lehigh County has a total area of 348 square miles (900 km2), 345 square miles (890 km2) of which is land and 3.1 square miles (8.0 km2) (0.9%) of which is water.[9]

Topography

See also: Blue Mountain (Pennsylvania) and South Mountain (Eastern Pennsylvania)

Lehigh County borders two Appalachian mountain ridges. To the north, the county borders Blue Mountain, which has an altitude of 1,300 to 1,604 feet (396 to 489 m). To the south, it is bordered by South Mountain, which has an altitude of 700 to 1,100 feet (210 to 340 m) and cuts through the southern portions of both Lehigh and Northampton counties. The Lehigh County's highest point is near Germansville at Bake Oven Knob, a mass of Tuscarora conglomeratic rocks that rise about 100 feet (30 m) above the main Blue Mountain ridge in northwestern Heidelberg Township.[10]

Lehigh County is part of the Delaware River watershed. Most of the county is drained by the Lehigh River and its tributaries, though the Schuylkill River also drains regions in the county's south through Perkiomen Creek and (in the county's northwest) through Maiden Creek.

From 1947 until 1994, Lehigh County was served exclusively by the 215 area code. With the county's growing population, area code 610 was also allocated to the county in 1994. Today, Lehigh County is covered largely by the 610 area code.
