The earliest European settlement was slightly north of Frederick in Monocacy, Maryland. Monocacy was founded before 1730 (when the Indian trail became a wagon road) and was abandoned before the American Revolutionary War, likely due to the river's periodic flooding, hostilities predating the French and Indian War, or simply Frederick's better location with easier access to the Potomac River near its confluence with the Monocacy.
In 1748, Frederick County was formed by carving a section off of Prince George's County. Frederick Town (now Frederick) was made the county seat of Frederick County.[16] The county originally extended to the Appalachian mountains (areas further west being disputed between the colonies of Virginia and Pennsylvania until 1789). The current town's first house was built by a young German Reformed schoolmaster from the Rhineland Palatinate named Johann Thomas Schley (died 1790), who led a party of immigrants (including his wife, Maria Von Winz) to the Maryland colony. The Palatinate settlers bought land from Dulany on the banks of Carroll Creek, and Schley's house stood at the northwest corner of Middle Alley and East Patrick Street into the 20th century. Schley's settlers also founded a German Reformed Church (today known as Evangelical Reformed Church, and part of the UCC). Probably the oldest house still standing in Frederick today is Schifferstadt, built in 1756 by German settler Joseph Brunner and now the Schifferstadt Architectural Museum.
Other German settlers in Frederick were Evangelical Lutherans, led by Rev. Henry Muhlenberg. They moved their mission church from Monocacy to what became a large complex a few blocks further down Church Street from the Anglicans and the German Reformed Church. Methodist missionary Robert Strawbridge, who accepted an invitation to preach at Frederick town in 1770, and Francis Asbury, who arrived two years later, both helped found a congregation which became Calvary Methodist Church, worshipping in a log building from 1792 (although superseded by larger buildings in 1841, 1865, 1910 and 1930).[17] Frederick also had a Catholic mission, to which Rev. Jean DuBois was assigned in 1792, which became St. John the Evangelist Church (built in 1800).
As the county seat for Western Maryland, Frederick not only was an important market town but also the seat of justice. Although Montgomery County and Washington County were split off from Frederick County in 1776, Frederick remained the seat of the smaller (though still large) county. Important lawyers who practiced in Frederick included John Hanson, Francis Scott Key and Roger B. Taney.
Frederick was also known during the nineteenth century for its religious pluralism, with one of its main thoroughfares, Church Street, hosting about a half dozen major churches. In 1793, All Saints Church hosted the first confirmation of an American citizen, by the newly consecrated Episcopal Bishop Thomas Claggett. That original colonial building was replaced in 1814 by a brick classical revival structure. It still stands today, although the principal worship space has become an even larger brick gothic church joining it at the back and facing Frederick's City Hall (so the parish remains the oldest Episcopal Church in western Maryland).[18] The main Catholic church, dedicated to St. John the Evangelist, was built in 1800, then rebuilt in 1837 (across the street) one block north of Church Street on East Second Street, where it still stands along with a school and convent established by the Visitation Sisters.[19] The stone Evangelical Lutheran Church of 1752 was also rebuilt and enlarged in 1825, then replaced by the current twin-spired structure in 1852.[20]
The oldest African-American church in the town is Asbury United Methodist Church, founded as the Old Hill Church, a mixed congregation in 1818. It became an African-American congregation in 1864, renamed Asbury Methodist Episcopal Church in 1870, and built its current building on All Saints Street in 1921.[21]
Together, these churches dominated the town, set against the backdrop of the first ridge of the Appalachians at Catoctin Mountain. The abolitionist poet John Greenleaf Whittier later immortalized this view of Frederick in his poem to "Barbara Fritchie": "The clustered spires of Frederick stand/Green-walled by the hills of Maryland."[22]
When U.S. PresidentThomas Jefferson commissioned National Road from Baltimore toward St. Louis, eventually built to Vandalia, then the state capital of Illinois, National Pike ran through Frederick along Patrick Street; it later became U.S. Route 40. Frederick's Jacob Engelbrecht corresponded with Jefferson in 1824 and received a transcribed psalm from Jefferson in return. Engelbrecht kept a diary from 1819 through 1878, which remains an important first-hand account of 19th century life on National Road.[23][24] An important house remaining from this era is the Tyler Spite House, built in 1814 at 112 W. Church Street by a local doctor to prevent the city from extending Record Street south through his land to meet West Patrick Street.[25][26]
Frederick also became one of the new nation's leading mining counties in the early 19th century. It exported gold, copper, limestone, marble, iron, and other minerals. As early as the American Revolution, Catoctin Furnace near Thurmont became an important source of iron production.[27] Other mining areas split off into Washington County, Maryland and Allegheny County, Maryland but continued to ship their ore through Frederick to Eastern cities and ports.
Frederick became Maryland's capital city briefly in 1861, as the legislature moved from Annapolis to vote on the secession question. President Lincoln arrested several members, and the assembly was unable to convene a quorum to vote on secession.
As a major crossroads, Frederick, like Winchester, Virginia, and Martinsburg, West Virginia, saw considerable action during the American Civil War.[29]Slaves also escaped from or through Frederick (since Maryland was still a "slave state" although it had not seceded) to join the Union forces, work against the Confederacy and seek freedom. During the Maryland campaigns, both Union and Confederate troops marched through the city. Frederick also hosted several hospitals to nurse the wounded from those battles, as is related in the National Museum of Civil War Medicine on East Patrick Street.
A legend related by John Greenleaf Whittier claimed that Frederick's Pennsylvania Dutch women (including Barbara Fritchie who reportedly waved a flag) booed the Confederates in September 1862, as General Stonewall Jackson led his light infantry division through Frederick on his way to the battles of Crampton's, Fox's and Turner's Gaps on South Mountain and Antietam near Sharpsburg. Union Major General Jesse L. Reno's IX Corps followed Jackson's men through the city a few days later on the way to the Battle of South Mountain, where Reno died. The sites of the battles are due west of the city along the National Road, west of Burkittsville. Confederate troops under Jackson and Walker unsuccessfully attempted to halt the Federal army's westward advance into the Cumberland Valley and towards Sharpsburg. Gathland State Park has the War Correspondents' Memorial stone arch erected by reporter/editor George Alfred Townsend (1841–1914). The 1889 memorial commemorating Major General Reno and the Union soldiers of his IX Corps is on Reno Monument Road west of Middletown, just below the summit of Fox's Gap, as is a 1993 memorial to slain Confederate Brig. Gen. Samuel Garland Jr., and the North Carolina troops who held the line.
President Abraham Lincoln, on his way to visit Gen. George McClellan after the Battle of South Mountain and the Battle of Antietam, delivered a short speech at what was then the B&O Railroad depot at the current intersection of East All Saints and South Market Streets. A plaque commemorates the speech (at what is today the Frederick Community Action Agency, a Social Services office).
At the Prospect Hall mansion off Jefferson Street to Buckeystown Pike near what is now Butterfly Lane, in the early morning hours of June 28, 1863, a messenger arrived from President Abraham Lincoln and General-in-Chief Henry Halleck, informing General George Meade that he would be replacing General Joseph Hooker after the latter's disastrous performance at Chancellorsville in May. The Army of the Potomac camped around the Prospect Hall property for the several days as skirmishers pursued Lee's Confederate Army of Northern Virginia before Gettysburg. A large granite rectangular monument made from one of the boulders at the "Devil's Den" in Gettysburg to the east along the driveway commemorates the midnight change-of-command.
In July 1864, in the third Southern invasion, Confederate troops led by Lieutenant General Jubal Early occupied Frederick and extorted $200,000 ($3.9 million in 2023 dollars[30]) from citizens for not razing the city on their way to Washington, D.C.[31] Union troops under Major General Lew Wallace fought a successful delaying action, in what became the last significant Confederate advance at the Battle of Monocacy, also known as the "Battle that Saved Washington." The Monocacy National Battlefield lies just southeast of the city limits, along the Monocacy River at the B&O Railroad junction where two bridges cross the stream: an iron-truss bridge for the railroad and a covered wooden bridge for the Frederick-Urbana-Georgetown Pike, which was the site of the main battle of July 1864. Some skirmishing occurred further northeast of town at the stone-arched "Jug Bridge" where the National Road crossed the Monocacy; and an artillery bombardment occurred along the National Road west of town near Red Man's Hill and Prospect Hall mansion as the Union troops retreated eastward. Antietam National Battlefield and South Mountain State Battlefield Park which commemorates the 1862 battles are located 23 miles and 35 miles respectively to the west-northwest. While Gettysburg National Battlefield of 1863 lies approximately 35 miles (56 km) to the north-northeast.
The reconstructed home of Barbara Fritchie stands on West Patrick Street, just past Carroll Creek linear park. Fritchie, a significant figure in Maryland history in her own right, is buried in Frederick's Mount Olivet Cemetery. British Prime Minister Winston Churchill quoted Whittier's poem to President Franklin D. Roosevelt when they stopped here in 1941 on a car trip to the presidential retreat, then called "Shangra-La" (now "Camp David") within the Catoctin Mountains near Thurmont.
Late 19th century
Admiral Winfield Scott Schley (1839–1911) was born at "Richfields", the mansion home of his father. He became an important naval commander of the American fleet on board his flagship and heavy cruiser USS Brooklyn along with Admiral William T. Sampson in the Battle of Santiago de Cuba off the shores of the Spanish island colony of Cuba in the Spanish–American War in 1898. Major Henry Schley's son, Dr. Fairfax Schley, was instrumental in setting up the Frederick County Agricultural Society and the Great Frederick Fair.[32] Gilmer Schley served as Mayor from 1919 to 1922, and the Schleys remained one of the town's leading families into the late-20th century.
Nathaniel Wilson Schley, a prominent banker, and his wife Mary Margaret Schley helped organize and raise funds for the annual Great Frederick Fair, one of the two largest agricultural fairs in the State. Since the 1960s, the fair has featured many outstanding country-western singers and become a major music festival.[33] Schley Avenue commemorates the family's role in the city's heritage.
The Frederick and Pennsylvania Line railroad ran from Frederick to the Pennsylvania–Maryland State line, a/k/a Mason–Dixon line.[34] Chartered in 1867, construction began in 1869 and the line opened October 8, 1872. However, it defaulted on its interest payments in 1874 and was acquired by the Pennsylvania Railroad in 1875, which formed a new division to operate the rail line. In the spring of 1896, the Frederick and Pennsylvania Line railroad was liquidated in a judicial sale to the Pennsylvania Railroad for $150,000. The railroad survived through mergers and the Penn-Central bankruptcy. However, the State of Maryland acquired the Frederick and Pennsylvania Line in 1982. As of 2013, all but two miles (3.2 km) at the southern terminus at Frederick still exist, operated by either the Walkersville Southern, or the Maryland Midland Railway (MMID) railroads.
Jewish pioneers Henry Lazarus and Levy Cohan settled in Frederick in the 1740s as merchants. Mostly German Jewish immigrants organized a community in the mid-19th century, creating the Frederick Hebrew Congregation in 1858. Later the congregation lapsed, but was reorganized in 1917 as a cooperative effort between the older settlers and more recently arrived Eastern European Jews under the name Beth Sholom Congregation.
In 1905, Rev. E. B. Hatcher started the First Baptist Church of Frederick.
After the Civil War, the Maryland legislature established racially segregated public facilities by the end of the 19th century, re-imposing white supremacy. Black institutions were typically underfunded in the state, and it was not until 1921 that Frederick established a public high school for African Americans. First located at 170 West All Saints Street, it moved to 250 Madison Street, where it eventually was adapted as South Frederick Elementary. The building presently houses the Lincoln Elementary School. The Laboring Sons Memorial Grounds, a cemetery for free blacks, was founded in 1851.
According to the U.S. Census Bureau, the city has a total area of 23.96 square miles (62.06 km2), of which 23.79 square miles (61.62 km2) is land and 0.18 square miles (0.47 km2) is water.[35] The city's area is predominantly land, with small areas of water being the Monocacy River, which runs to the east of the city, Carroll Creek (which runs through the city and causes periodic floods, such as that during the summer of 1972 and fall of 1976), as well as several neighborhood ponds and small city owned lakes, such as Culler Lake, a man-made small body of water in the downtown area.[36]
Climate
The climate in this area is characterized by hot, humid summers and generally cool winters. It lies to the west of the fall line, which gives the city slightly lower temperatures compared to locales further east. According to the Köppen Climate Classification system, Frederick has a humid subtropical climate, abbreviated Cfa on climate maps.[37] Frederick is also the site of the highest temperature recorded in Maryland at 109 °F (42.8 °C) on July 10, 1936.[38]
In regard to minority group growth, the 2020 census data show the city's Hispanic population at 16,368, a 74 percent increase compared with 9,402 in 2010,[44] making Hispanics/Latinos the fastest growing race group in the city and in Frederick county (87 percent increase[45]). Frederick city had 4,425 Asian residents in 2020, a 16 percent increase from the city's 3,800 Asian residents in 2010. The city's Black or African-American population increased roughly 20 percent, from 12,144 in 2010 to 14,526 in 2020.[44]
According to American Community Survey estimates in 2021, for the roughly 33,907 households in the city, 30.4% had children under the age of 18 living with them, 41.4% were married couples living together, 30.4% had a female householder with no spouse/partner present, and 20.3% male householders with no spouse/partner present. Approximately 14.8% of all households were made up of individuals living alone and 2.9% had someone living alone who was 65 years of age or older. The average household size was 2.29 and the average family size was 2.97.[46]
Economy
Frederick's relative proximity to Washington, D.C., has always been an important factor in the development of its local economy, along with the presence of Fort Detrick, its largest employer.
Frederick is the home of Riverside Research Park, a large biomedical research park located on Frederick's east side. Tenants include the relocated main offices of the National Cancer Institute's Frederick National Laboratory for Cancer Research as well as Charles River Labs. As a result of continued and enhanced federal government investment, the Frederick area will likely maintain a continued growth pattern over the next decade.[47] Frederick has also been impacted by recent national trends centered on the gentrification of the downtown areas of cities across the nation (particularly in the northeast and mid-Atlantic), and to re-brand them as sites for cultural consumption.
The Frederick Historic District in the city's downtown houses more than 200 retailers, restaurants and antique shops along Market, Patrick and East Streets.[48] Restaurants feature a diverse array of cuisines, including Italian American, Thai, Vietnamese, and Cuban, as well as a number of regionally recognized dining establishments.
In addition to retail and dining, downtown Frederick is home to 600 businesses and organizations totaling nearly 5,000 employees. A growing technology sector can be found in downtown's historic renovated spaces, as well as in new office buildings located along Carroll Creek Park.
Carroll Creek Park began as a flood control project in the late 1970s.[48] It was an effort to reduce the risk to downtown Frederick from the 100-year floodplain and restore economic vitality to the historic commercial district. Today, more than $150 million in private investing is underway or planned in new construction, infill development or historic renovation in the park area.[48]
The first phase of the park improvements, totaling nearly $11 million in construction, run from Court Street to just past Carroll Street.[48] New elements to the park include brick pedestrian paths, water features, planters with shade trees and plantings, pedestrian bridges and a 350-seat amphitheater for outdoor performances.
A recreational and cultural resource, the park also serves as an economic development catalyst, with private investment along the creek functioning as a key component to the park's success. More than 400,000 sf of office space; 150,000 sf of commercial/retail space; nearly 300 residential units; and more than 2,000 parking spaces are planned or under construction.
On the first Saturday of every month, Frederick hosts an evening event in the downtown area called "First Saturday". Each Saturday has a theme, and activities are planned according to those themes in the downtown area (particularly around the Carroll Creek Promenade). The event spans a ten-block area of Frederick and takes place from 5 p.m. to 9 p.m. During the late spring, summer, and early fall months, this event draws particularly large crowds from neighboring cities and towns in Maryland, and nearby locations in the tri-state area (Virginia and Pennsylvania). The average number of attendees visiting downtown Frederick during first Saturday events is around 11,000, with higher numbers from May to October.[49]
Top employers
According to the county's comprehensive annual financial reports, the top employers by number of employees in the county are the following. ("NR" indicates the employer was not ranked among the top ten employers that year.)
Frederick is well known for the "clustered spires" skyline of its historic downtown churches. These spires are depicted on the city's seal and many other city-affiliated logos and insignia. The phrase "clustered spires" is used as the name of several city locations such as Clustered Spires Cemetery and the city-operated Clustered Spires Golf Course.
The scale of the older part of the city is dense, with streets and sidewalks suitable for pedestrians, and a variety of shops and restaurants, comprising what Forbes magazine in 2010 called one of the United States' "Greatest Neighborhoods".[52]
Frederick has a bridge painted with a mural titled Community Bridge. The artist William Cochran has been acclaimed for the trompe-l'œil realism of the mural. Thousands of people sent ideas representing "community", which he painted on the stonework of the bridge. The residents of Frederick call it "the mural", "painted bridge", or more commonly, the "mural bridge".[53]
Theatre and arts
The Frederick Arts Council is the designated arts organization for Frederick County. The organization is charged with promoting, supporting, and advocating the arts. There are over ten art galleries in downtown Frederick, and three theaters are located within 50 feet of each other (Cultural Arts Center, Weinberg Center for the Arts, and the Maryland Ensemble Theatre). Frederick is the home of The Delaplaine Visual Arts Education Center, a leading non-profit in the region,[54] as well as the Maryland Shakespeare Festival.
In August 2007, the streets of Frederick were adorned with 30 life-size fiberglass keys as part of a major public art project entitled "The Keys to Frederick". In October 2007, artist William Cochran created a large-scale glass project titled The Dreaming. The project is in the historic theater district, across from the Wienberg Center for the Arts.[55]
The Maryland Ensemble Theatre (MET), a professional theater company, is housed on the lower level of the Francis Scott Key Hotel. The MET first produced mainstage theater in 1997, but the group began performing together with its creation of The Comedy Pigs sketch comedy/improv troupe in April 1993.[56] The students at Hood College also have a theatre club and put on shows at least once during the school year, sometimes two shows are presented during the school year.[57]
The film Blair Witch Project (1999) was set in the woods west of Burkittsville, Maryland, in western Frederick County, but it was not filmed there.

Religion
There are numerous religious denominations in Frederick: the first churches were established by early Protestant settlers, followed by Irish Catholics and other European Catholics.
St. Paul African Methodist Episcopal Church in Della (now Urbana) is one of the oldest active African-American churches in Frederick County, Maryland, according to a testimonial placed in its cornerstone which stated that it was the first A.M.E. church built in the southern part of Frederick County. It was built in 1916 on a foundation first laid in 1908.[63]
Other denominations represented in Frederick City and in the surrounding county include large numbers of Brethren, as well as some Pentecostal churches.[64] Quinn Chapel, of the African Methodist Episcopal (A.M.E.)

This intersection has created an efficient distribution network for commercial traffic in and out, as well as through the city.
Major roads and streets in Frederick are intersected by:
Beginning in the 1990s, Frederick has invested in several urban infrastructure projects, including streetscape, new bus routes, as well as multi-use paths.[87] A circular road, Monocacy Boulevard, is an important component to the revitalization of its historic core.[88]
The Mayor's Ad-hoc Bicycle Committee was formed in 2010 and given the mission to achieve designation for the City as a Bicycle Friendly Community (BFC) by the League of American Bicyclists. The first application resulted in an Honorable Mention. Upon reapplication In 2012, Frederick achieved the bronze level BFC designation.[89] The City's third application resulted in re-certification as a Bronze Bicycle Friendly Community. Work is ongoing to achieve an even stronger designation (Silver) at the time of the next application.
In 2013, the Mayor's Ad-hoc Bicycle Committee was expanded in scope to include pedestrian issues and was formally adopted by Resolution 13-08 as a permanent standing committee called the Bicycle and Pedestrian Advisory Committee (BPAC). The BPAC advises City officials and staff on the sound development, management, and safe use of The City of Frederick's pedestrian and bicycle systems as they relate to infrastructure, accessibility, and promoting the benefits of these systems.
