About Delaware County
Delaware County Timeline
Delaware County, located in southeastern Pennsylvania, has a rich history that spans centuries. The area was originally inhabited by the Lenape Native American tribe, who were the first to settle in the region. European colonization began in the early 17th century when Dutch and Swedish settlers established trading posts along the Delaware River. The Dutch were the first to claim the land, followed by the Swedes, who established the New Sweden colony in present-day Delaware County.
In 1682, Delaware County, along with the rest of Pennsylvania, became a part of the English colony founded by William Penn. The county's strategic location and natural resources attracted early settlers, leading to the establishment of numerous towns and villages. The region played a significant role during the American Revolution, as several major battles were fought in Delaware County and nearby Philadelphia. Valley Forge, located in present-day Montgomery County, served as the winter encampment for George Washington's Continental Army in 1777-1778.
The Industrial Revolution brought further growth and prosperity to Delaware County in the 19th century. Industries like textile mills, ironworks, and shipbuilding thrived, fueling economic development and immigration. The county's proximity to Philadelphia, along with the expansion of railways and trolley lines, facilitated the transportation of goods and people. The population continued to grow, and suburbanization accelerated in the 20th century as more people moved out of Philadelphia and into the surrounding areas, including Delaware County.
Today, Delaware County remains a vibrant and diverse community. Its historical landmarks, such as the Pennsylvania Military Museum, Civil War Library and Museum, and Swarthmore College, continue to highlight its heritage. The county also boasts a thriving economy, with a diverse range of industries, including healthcare, education, and manufacturing. Despite facing challenges, such as urbanization and population growth, Delaware County continues to adapt and evolve while preserving its rich historical legacy.
