Frederick County Maryland

A Historical Overview of Frederick County, Maryland

Frederick County, located in north-central Maryland, is one of the state's most historically significant counties. Established in 1748, it has played a vital role in colonial expansion, the American Revolution, the Civil War, and the development of industry and transportation. With its strategic location between Washington, D.C., and Pennsylvania, Frederick County has been a key crossroads in American history, influencing both military and economic developments. Today, the county blends historic preservation with modern growth, making it a centerpiece of Maryland’s heritage.

Pre-Colonial and Indigenous History (Before 1700s)

Before European settlement, Frederick County was inhabited by Indigenous peoples, particularly the Susquehannock and Tuscarora tribes. These groups relied on the region’s fertile valleys, rivers, and forests for hunting, fishing, and agriculture.

  • The Monocacy River served as a crucial travel and trade route for Indigenous people.
  • By the late 1600s, European diseases, warfare, and encroachment led to the displacement of most Indigenous communities.

Colonial Settlement and Founding (1700s)

European Settlement

By the early 18th century, European settlers—mainly of German, English, and Scots-Irish descent—began arriving in what is now Frederick County. Many settlers came from Pennsylvania and Virginia, drawn by the region’s rich farmland, rivers, and natural resources.

Establishment of Frederick County (1748)

Frederick County was officially created in 1748 from parts of Prince George’s County, making it one of the earliest counties in western Maryland. The county seat, Frederick Town (now Frederick City), was founded around the same time and became a key hub for commerce and trade.

  • The town was named after Frederick Calvert, the Sixth Lord Baltimore.
  • The region’s economy was based on farming, milling, and early manufacturing.
  • The Catoctin Mountains and Monocacy River provided natural resources and transportation routes.

Religious Freedom and Diversity

Frederick County became known for its religious tolerance, attracting:

  • German Lutherans and Reformed Protestants
  • Catholics (including settlers from English and Irish backgrounds)
  • Quakers and Mennonites

One of the oldest churches in the region, Evangelical Lutheran Church in Frederick, was established in the mid-1700s.

Frederick County in the American Revolution (1775–1783)

During the American Revolution, Frederick County was a center of patriot activity:

  • Frederick County supplied troops and resources for the Continental Army.
  • Local ironworks, such as Catoctin Furnace, produced cannonballs and weaponry for the war effort.

One of the most notable figures from this period was Thomas Johnson, a Frederick County resident who became Maryland’s first governor and a close ally of George Washington.
