History
Jefferson County was established in the mid-19th century as Colorado was settled and organized into counties. Its name honors Thomas Jefferson, reflecting the period’s habit of naming places after leaders associated with American political philosophy and westward expansion. The county’s early economy centered on mining and trade, with towns like Golden growing as supply and cultural centers for nearby mining districts. Over the decades, the area transformed from mining outposts into a mature suburban and educational hub. The postwar era brought highways, growth in residential development, and the establishment of policy frameworks that shaped land use and public services. A key milestone in the county’s modern identity was the creation of the Jefferson County Open Space program, which established a long-term commitment to preserving open land for recreation, wildlife, and scenic value Jefferson County Open Space.
