As of the 2010 U.S. Census, the population was 240,336.[1] The county seat is Frederick.[2] Frederick County is included in the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area. Like other outlying sections of the Washington metropolitan area, Frederick County has experienced a rapid population increase in recent years.[3][4] It borders the southern border of Pennsylvania and the northeastern border of Virginia. The county is home to Catoctin Mountain Park (encompassing the presidential retreat Camp David) and to the U.S. Army's Fort Detrick. It has also been the home to several important historical figures like Francis Scott Key, Chris Rose, Zach Taylor, Matt Bennett, Thomas Johnson, Roger B. Taney, and Barbara Fritchie. EtymologyThe namesake of Frederick County and its county seat is unknown, but it probably was either Frederick, Prince of Wales, or Frederick Calvert, 6th Baron Baltimore.[5] HistoryFrederick County was created in 1748 by the Province of Maryland from parts of Prince George's County and Baltimore County. In 1776 following Independence, Frederick County was divided into three parts. The westernmost portion became Washington County, named after George Washington, the southernmost portion became Montgomery County, named after another Revolutionary War general, Richard Montgomery. The northern portion remained Frederick County. In 1837 a part of Frederick County was combined with a part of Baltimore County to form Carroll County which is east of current day Frederick County. The county has a number of properties on the National Register of Historic Places.[6] Geography{{Location map+ | USA Washington Metropolitan Area| caption =Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area[7] |width=380 | places = | label =Calvert | label_size=80 | marksize=2 | position =top | lat_deg =38.53 | lon_deg =-76.53 }} {{Location map~ | USA Washington Metropolitan Area| label =Charles | label_size=80 | marksize=2 | position =top | lat_deg =38.48 | lon_deg =-77.01 }} {{Location map~ | USA Washington Metropolitan Area| label =Frederick | label_size=80 | marksize=2 | position =top | lat_deg =39.47 | lon_deg =-77.4 }} {{Location map~ | USA Washington Metropolitan Area| label =Montgomery | label_size=80 | marksize=2 | position =top | lat_deg =39.14 | lon_deg =-77.2 }} {{Location map~ | USA Washington Metropolitan Area| label =Prince George's | label_size=80 | marksize=2 | position =right | lat_deg =38.83 | lon_deg =-76.85 }} {{Location map~ | USA Washington Metropolitan Area| label =Alexandria | label_size=80 | marksize=2 | position =bottom | lat_deg =38.804722 | lon_deg =-77.047222 }} {{Location map~ | USA Washington Metropolitan Area| label =Arlington | label_size=80 | marksize=2 | position =right | lat_deg =38.8807927 | lon_deg =-77.172196 }} {{Location map~ | USA Washington Metropolitan Area| label =Clarke | label_size=80 | marksize=2 | position =top | lat_deg =39.12 | lon_deg =-78 }} {{Location map~ | USA Washington Metropolitan Area| label =Fairfax | label_size=80 | marksize=2 | position =left | lat_deg =38.87 | lon_deg =-77.304377 }} {{Location map~ | USA Washington Metropolitan Area| label =Fairfax County | label_size=80 | marksize=2 | position =right | lat_deg =38.83 | lon_deg =-77.28 }} {{Location map~ | USA Washington Metropolitan Area| label =Falls Church | label_size=80 | marksize=2 | position =top | lat_deg =38.882222 | lon_deg =-77.171111 }} {{Location map~ | USA Washington Metropolitan Area| label =Fauquier | label_size=80 | marksize=2 | position =bottom | lat_deg =38.74 | lon_deg =-77.81 }} {{Location map~ | USA Washington Metropolitan Area| label =Loudoun | label_size=80 | marksize=2 | position =top | lat_deg =39.09 | lon_deg =-77.64 }} {{Location map~ | USA Washington Metropolitan Area| label =Manassas | label_size=80 | marksize=2 | position =right | lat_deg =38.751415 | lon_deg =-77.476396 }} {{Location map~ | USA Washington Metropolitan Area| label =Manassas Park | label_size=80 | marksize=2 | position =left | lat_deg =38.773564 | lon_deg =-77.453542 }} {{Location map~ | USA Washington Metropolitan Area| label =Prince William | label_size=80 | marksize=2 | position =bottom | lat_deg =38.7 | lon_deg =-77.48 }} {{Location map~ | USA Washington Metropolitan Area| label =Spotsylvania | label_size=80 | marksize=2 | position =top | lat_deg =38.18 | lon_deg =-77.65 }} {{Location map~ | USA Washington Metropolitan Area| label =Stafford | label_size=80 | marksize=2 | position =top | lat_deg =38.41 | lon_deg =-77.45 }} {{Location map~ | USA Washington Metropolitan Area| label =Fredericksburg | label_size=80 | marksize=2 | position =top | lat_deg =38.301829 | lon_deg =-77.470778 }} {{Location map~ | USA Washington Metropolitan Area| label =Warren | label_size=80 | marksize=2 | position =top | lat_deg =38.91 | lon_deg =-78.21 }} {{Location map~ | USA Washington Metropolitan Area| label =Washington | label_size=80 | marksize=2 | position =right | lat_deg =38.95 | lon_deg =-77.016389 }} {{Location map~ | USA Washington Metropolitan Area| label =Jefferson | label_size=80 | marksize=2 | position =top | lat_deg =39.31 | lon_deg =-77.86 }} According to the U.S. Census Bureau, the county has a total area of {{convert|667|sqmi}}, of which {{convert|660|sqmi}} is land and {{convert|7.2|sqmi}} (1.1%) is water.[8] It is the largest county in Maryland in terms of land area.[9] Frederick County straddles the boundary between the Piedmont Plateau Region and the Appalachian Mountains.
