In short: Susquehanna County, Pennsylvania, once thrived on coal mining and railways, reaching a population of nearly 50,000. Today, the landscape is defined by mountainous terrain and rural living, with an economy shifted toward retail, healthcare, and natural gas. Discover the history of this region, from colonial land wars to modern industry.

Formed in 1810 from Luzerne County, Susquehanna County has a history marked by territorial disputes. In the mid-1700s, settlers from Connecticut and Philadelphia arrived, leading to the Pennamite-Yankee Wars between 1769 and 1799. These conflicts arose because Connecticut’s land grant overlapped with Pennsylvania’s, eventually resulting in Connecticut surrendering its claims. By 1812, Montrose was established as the county seat, and the region began its development.

The post-Civil War era brought a period of prosperity driven by coal mining and the expansion of infrastructure. At its peak, the county supported nearly 50,000 residents. However, the Great Depression severely impacted the coal industry, and despite a brief resurgence during World War II, the sector eventually declined. This led to the closure of mines, the dismantling of railways, and a long-term economic shift. By January 1970, mainline passenger train services had ceased entirely, leaving only freight lines.

Today, the county is entirely rural, with 100% of its residents living outside urban areas. The economy now relies on retail, healthcare, public education, and government roles. Since 2008, unconventional natural gas drilling has become a significant factor, coinciding with a population decline of about 5.8% between 2010 and 2016. As of 2011, there were 1,079 active gas wells in the county. The region remains mountainous, featuring North Knob as its highest point, and has transitioned into a destination for skiing and tourism.
