Frederick County is located in Maryland, United States. As of the 2020 U.S. census, the population was 271,717. The county seat is Frederick. The county is part of the Capital region of the state.

Like other outlying sections of the Washington metropolitan area, Frederick County has experienced a rapid population increase since the 1980s. It borders the southern border of Pennsylvania and the northeastern border of Virginia.

Catoctin Mountain Park in the county is the location of Camp David, a U.S. presidential retreat, and Fort Detrick, a U.S. Army base.

Etymology

The namesake of Frederick County and its county seat is unknown, but it was probably either Frederick, Prince of Wales, or Frederick Calvert, 6th Baron Baltimore.

History

Frederick County was created in 1748 by the Province of Maryland from parts of Prince George's County and Baltimore County.

In 1776, following US 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.

Geography

According to the U.S. Census Bureau, the county has a total area of 667 sqmi, of which 660 sqmi is land and 7.2 sqmi (1.1%) is water. It is the largest county in Maryland in terms of land area.

Frederick County straddles the boundary between the Piedmont Plateau Region and the Appalachian Mountains. The county's two prominent ridges, Catoctin Mountain and South Mountain, form an extension of the Blue Ridge. The Middletown Valley lies between them.

Attractions in the Frederick area include the Clustered Spires, a monument to Francis Scott Key, the National Museum of Civil War Medicine, Monocacy National Battlefield and South Mountain battlefields, and the Schifferstadt Architectural Museum.

Law, government, and politics

Charter government

On December 1, 2014, Frederick County changed to a "charter home rule government".

Voters approved this governmental change at the November 6, 2012, election with 62,469 voting for the transition and 37,368 against. Previously, Frederick County had been governed by a five-member county commission that could only legislate in local matters with the prior consent of the Maryland General Assembly. Even that authority was limited to areas authorized by the General Assembly, enabling legislation, or public local laws. As a charter county, Frederick County is now governed by a seven-member county council, with five elected from districts and two elected at-large. A popularly elected county executive is responsible for providing direction, supervision, and administrative oversight of all executive departments, agencies, and offices. The council has broad power to act on most local matters.

Jan Gardner was elected the first Frederick County executive in 2014 and was re-elected in 2018.

The Frederick County state's attorney, first elected November 2, 2010, and re-elected in 2018 and 2022, is Charlie Smith, a Republican.

The sheriff of Frederick County is Republican Chuck Jenkins.

Frederick County's fire and rescue service is handled by a combination career and volunteer service delivery system. The county employs over 450 career firefighters. Volunteers of the 26 volunteer fire and rescue corporations number approximately 300 active operational members. Fire, rescue and emergency medical services, including advanced life support, are handled by career staffing supplemented by volunteers. The county has a Maryland State Police Medevac located at the Frederick Municipal Airport and is designated "Trooper 3". Trooper 3 handles calls throughout the state, but provides immediate assistance to local police, fire and rescue services.

Politics

Frederick County was once, like the rest of Appalachian and German-influenced Western Maryland, staunchly Republican, with Lyndon B. Johnson in 1964 being the last Democrat to carry it in a presidential election until Joe Biden carried the county in 2020. The growth of the county with migration from Washington D.C. had begun to narrow the margins starting from 2008, with John McCain only edging out Barack Obama by only 1,157 votes out of over one hundred thousand cast in the 2008 election.

Democratic strength is mostly concentrated in the city of Frederick, whereas Republican strength is located in the northern rural regions of the county. The county's suburbs, historically Republican-leaning, have become competitive in recent years.

In state-level elections, Republicans in Frederick rebounded to more historical levels in the 2010 Maryland gubernatorial and senatorial elections, giving the Republican Ehrlich–Kane ticket 55% to Democrat O'Malley–Brown's 45. Frederick voters also supported Republican Senate challenger Eric Wargotz over incumbent Democratic Senator Barbara Mikulski by a margin of 51–46, even as Mikulski was winning statewide by a landslide 61–37.

Despite its conservative reputation, Frederick County voted in favor of Maryland Question 6, which legalized same-sex marriage in Maryland. In the 2014 gubernatorial race, Republican Larry Hogan won Frederick County strongly with 63 percent of the vote compared to Democrat Anthony Brown's 35 percent. In the 2018 elections, despite increased support for Hogan, the Democrats experienced significant gains, securing a majority on the County Council and winning District 3B in the House of Delegates. The Senate election also saw incumbent U.S. Senator Ben Cardin win Frederick County with 51.7% of the vote.

After Biden's win in 2020, the trend towards Democrats continued in 2022, as Democrats increased their majority on the County Council by one seat and gubernatorial candidate Wes Moore won the county with over 53% of the vote compared to 43% for Republican and Emmitsburg resident Dan Cox, the first time Frederick County voted for a Democratic gubernatorial candidate since William Donald Schaefer's landslide victory in 1986. In the Senate election also held in 2022, incumbent Democratic Senator Chris Van Hollen won the county 55.3% to 44.6% over Republican Chris Chaffee.
