About Lehigh County
Lehigh County Timeline
Lehigh County, Pennsylvania has a rich history spanning back to its founding in 1812. The area was originally settled by Native American tribes, including the Delaware and Shawnee, who utilized the region's fertile land for farming and hunting. European settlers began to arrive in the 18th century, drawn by the promise of natural resources and fertile soil.
The county's development was heavily influenced by its proximity to the Lehigh River and the growth of the coal and iron industries in the 19th century. The discovery of anthracite coal in the nearby mountains fueled the growth of the mining industry, leading to the establishment of coal mines and the construction of the Lehigh Canal to transport coal to Philadelphia. The presence of vast iron ore deposits also gave rise to the iron industry, with numerous foundries and rolling mills being established throughout the county.
Lehigh County saw significant growth and urbanization during the industrial revolution, with the city of Allentown becoming a major center for manufacturing and commerce. The arrival of the railroad in the mid-19th century further contributed to the county's development, facilitating transportation and trade. As a result, Allentown became known as the "City without Walls," reflecting its economic prosperity and diverse population.
In the 20th century, Lehigh County continued to experience growth and diversification. The decline of the coal and iron industries led to a shift towards other sectors, such as healthcare, education, and technology. The county's central location in the eastern part of Pennsylvania has also made it a transportation hub, with major highways and a regional airport serving the area.
Overall, Lehigh County's history has been shaped by its natural resources, industrial growth, and strategic location. Today, the county is known for its thriving economy, cultural attractions, and historical significance as a key player in the industrialization of America.
