==Etymology==
Upper Marlboro was established in 1706 as "Marlborough Town", after [[John Churchill, 1st Duke of Marlborough]], whose heraldic arms is depicted on town insignia. In 1744, the town was renamed to "Upper Marlborough". In the late 19th century, the town's name changed from Upper Marlborough to Upper Marlboro. The name change is linked to a postal clerk who felt that the last three letters, "ugh", did not properly fit on the rubber stamps being used at the time. By 1893, postal guides were referring to the town as Upper Marlboro, though it took several more decades for the new spelling to become widely accepted among residents. Even as late as 1925, the old spelling still saw widespread unofficial usage. Despite a proposed ballot to have it formally changed back in 1968, the new name stuck, and by 1971, the old spelling, while not completely vanquished, had become severely deprecated.<ref>{{Cite book|url=https://oldalsbooks.com/products/a-history-of-upper-marlboro-prince-georges-county-maryland-1971-james-shreve?variant=43906326593731|title=A History of Upper Marlboro, Prince George's County, Maryland|date=May 8, 1971|page=4|first=James|last=Shreve|publisher=Baker Printing Company|location=107 N 6th Street, Denton, Maryland, 21629|access-date=February 8, 2025|quote=Today it is called Marlboro by some of the inhabitants, and Marlborough by others.

==History==
[[File:PGcourthouse3.JPG|thumb|upright=1|The main entrance to the [[Prince George's County, Maryland|Prince George's County]] courthouse in December 2008]]
[[File:PGcourthouse2.JPG|thumb|upright=1|The Three Horse Statue featured prominently in front of the county courthouse in December 2008]]
The area of Upper Marlboro was first settled around 1695. It was named after [[John Churchill, 1st Duke of Marlborough]], an ancestor of [[Winston Churchill]]. The land, which was to become the town, was part of several estates known as Grove Landing, Meadows, and Darnall's Chance, owned by the Brooke, Beall, and Darnall families, respectively.

[[Darnall's Chance]], also known as the Buck House, Buck-Wardrop House, or James Wardrop House, is a historic home located at 14800 Governor Oden Bowie Drive, in Upper Marlboro. It is named after Colonel Henry Darnall, a wealthy Roman Catholic planter, who was the Proprietary Agent of Charles Calvert, 3rd Baron Baltimore and who served for a time as Deputy Governor of the Province. The house itself was built c. 1742 by a merchant named James Wardrop, after he bought some of the land from Eleanor Darnall Carroll and her husband. Today, Darnall's Chance houses the Darnall's Chance House Museum, an historic house museum that opened to the public in 1988.

In 1706, Marlborough Town was established as a port town by the Act for the Advancement of Trade and Erecting Ports and Towns.<ref>{{Cite web |last=United States Department of the Interior -National Park Service |date=October 28, 2012 |title=National Register of Historic Places Registration Form |url=https://npgallery.nps.gov/GetAsset/b6a1a225-2486-4d8e-af00-f36b36d63bdb |access-date=February 18, 2024 |website=Town of Upper Marlboro Residential Area |archive-date=February 19, 2024 |archive-url=https://web.archive.org/web/20240219005212/https://npgallery.nps.gov/GetAsset/b6a1a225-2486-4d8e-af00-f36b36d63bdb |url-status=live }}</ref> It was declared that the town would be constructed, "at the upper landing on the Western Branch, commonly called Colonel Belt's landing." County surveyor Thomas Truman Greenfield conducted a survey of {{convert|100|acre|km2}} of the three estates from which the town would be formed. Streets, alleys, a meetinghouse, lots for small businesses, and 100 lots to be used for homes were laid out. The earliest plans showed the town being laid out in a grid pattern with an L shape.{{citation needed|date=September 2018}} In 1718 residents asked the county government's general assembly, then based in Charles Town, via petition to move the county seat to Upper Marlboro. The county seat has been there since that time.<ref name=HernandezLargo>{{cite news|author=Hernández, Arelis R.|url=https://www.washingtonpost.com/local/md-politics/baker-wants-to-move-government-headquarters-to-largo-lawmakers-say/2015/07/22/3f5fa562-271e-11e5-b77f-eb13a215f593_story.html|title=Baker wants to move government headquarters to Largo, lawmakers say|newspaper=[[Washington Post]]|date=July 22, 2015|access-date=September 11, 2018|archive-date=June 12, 2018|archive-url=https://web.archive.org/web/20180612211347/https://www.washingtonpost.com/local/md-politics/baker-wants-to-move-government-headquarters-to-largo-lawmakers-say/2015/07/22/3f5fa562-271e-11e5-b77f-eb13a215f593_story.html|url-status=live}}</ref>

Residents of the area were not happy with Greenfield's initial layout and petitioned the General Assembly to have the town replatted. In 1744, the new survey was approved and the town was given a new name, Upper Marlborough. Upper was added to distinguish the town from the community of Marlboro (now known as [[Lower Marlboro, Maryland|Lower Marlboro]]) in [[Calvert County, Maryland|Calvert County]].

Early in its life, when the western branch of the [[Patuxent River]] was still navigable, the town served as a port town for tobacco ships. The town blossomed into an agricultural, social, and political hot spot. Farms, many of which raised tobacco, dominated the surrounding areas.

In 1721, a [[courthouse]] was constructed in the town. The county seat was then moved from Charles Town, on the banks of the Patuxent, to Upper Marlborough. The courthouse was built with money from a 12-pound tobacco tax imposed on county inhabitants. One of the first laws passed at the courthouse was the Public School Act, which established a public school system.

In 1814, Upper Marlboro was seized by British forces under the command of [[Robert Ross (British Army officer)|Major-General Robert Ross]] and [[George Cockburn|Rear Admiral George Cockburn]] during the campaign leading up to the [[Battle of Bladensburg]] and the [[Burning of Washington]].<ref>Latimer, John ''1812: War with America'' (Cambridge, MA: Belknap Press of Harvard University, 2007), 311.</ref>

During the late 18th and early 19th centuries, many prominent merchants, lawyers, and politicians lived and worked in the area. [[Horse racing]] came to the town around the mid-18th century and attracted many people from the surrounding areas. The [[Maryland Jockey Club]] sponsored spring and summer races at the race track south of town, and racing continued there until 1972, when they were moved to the [[Bowie Race Track]]. The race track is now part of the Equestrian Center owned by Prince George's County.

In 1870, the town was incorporated by the [[Maryland General Assembly]]. A volunteer fire department was organized in 1886, and the Marlborough Fire Association was incorporated the following year.

In 1878, [[Lynching of Michael Green|Michael Green]], an [[African-American]] man accused of assaulting a white woman, was taken from the country jail and hanged from a tree outside of town.<ref name=kent-9-7-78>{{cite news|title=Lynching at Upper Marlboro|url=https://msa.maryland.gov/megafile/msa/speccol/sc3500/sc3520/013700/013788/images/18780907kn_mike_green_lynching.pdf|access-date=May 13, 2015|publisher=The Kent News|date=September 7, 1878|archive-date=May 18, 2015|archive-url=https://web.archive.org/web/20150518075753/http://msa.maryland.gov/megafile/msa/speccol/sc3500/sc3520/013700/013788/images/18780907kn_mike_green_lynching.pdf|url-status=live}}</ref> An "iron bridge just between the town and the railroad depot" was the site of two more lynchings.

Since its initial conception, the town has changed quite a bit. It initially boomed as a port town for tobacco trade, but the clearing and cultivation of land for farming would lead to erosion in the area. Over the years this erosion caused [[sedimentation]], leading the Western Branch to become unnavigable. The fields of tobacco that once dominated the area have been converted over to residential developments, with the number of farms dwindling each year.

As it is Prince George's county seat, located within the town are the Prince George's County Courthouse, County Administration Building, the Board of Education, and the headquarters of the [[Prince George's County Sheriff's Office]]. The town's atmosphere is remarkably different, depending on the time of day.<ref>{{cite web |website=www.uppermarlboromd.gov |lang=en |url=http://www.uppermarlboromd.gov/about/history/pppf.pdf |access-date=April 11, 2023 |archive-url=https://web.archive.org/web/20090207012503/http://www.uppermarlboromd.gov/about/history/pppf.pdf |archive-date=February 7, 2009 |title=Proud Past {{ndash}} Promising Future}}</ref>

===Prince George's County courthouse===
The courthouse has been a critical part of the town since it became the county seat in 1721. Since then, the courthouse in Upper Marlboro has seen many changes. Between 1798 and 1801, a new courthouse was constructed on the site of the old one. The courthouse was again rebuilt in the 1880s.

In 1939, the courthouse was substantially expanded and rebuilt. During this time, the building gained its famous stone [[Ionic columns]]. According to county historian Susan Pearl, "They wanted the neo-classic [[Georgian architecture|Georgian]] university campus building, and that's what they got." The total cost of the revision was $178,000.

Small additions were made in 1947 and 1969.

In the early 1990s, a new courthouse was erected behind the existing courthouse. The new courthouse, composed of the Marbury and Bourne wing, was completed in 1991. The new building occupies {{convert|360000|sqft|m2}} of space and cost $80 million. The old courthouse was then designated as the Duvall Wing and was attached to the new section by walkways.

In May 2003, the old courthouse was closed for a $25 million renovation. On November 3, 2004, two months before the building was scheduled to reopen, a fire broke out and destroyed much of the {{convert|151000|sqft|m2|adj=on}} building. The fire left only a charred skeleton of the [[cupola]], which had overlooked Main Street for 64 years.<ref>{{citation

===Proposed move to Largo===
Since the 1990s, the Prince George's County government has been purchasing land in [[Largo, Maryland]], due to its convenient location near the [[Washington Metro]] and interstate highways. In 2015, County Executive [[Rushern Baker]] recommended the move of the county's seat from Upper Marlboro to Largo so that residents could be better served.<ref>{{cite web | url=http://greatergreaterwashington.org/post/27571/prince-georges-could-move-its-government-closer-to-more-residents/ | title=Prince George's County could move its government closer to more residents | access-date=July 28, 2015 | archive-date=July 30, 2015 | archive-url=https://web.archive.org/web/20150730234328/http://greatergreaterwashington.org/post/27571/prince-georges-could-move-its-government-closer-to-more-residents/ | url-status=live }}</ref>

Major features of the town include the courthouse, jail, county office building, board of education, and a lake with a walking path. Just to the south of town is the Prince George's Equestrian Center which is the location of the annual county fair, a major annual antiques show and [[The Show Place Arena]] on the former Marlboro racetrack grounds. This arena is used for events such as hockey games, circuses, rodeos, conventions, trade shows, and graduation ceremonies of many regional high schools, as well as daily overflow parking for county governmental employees, jurors, and visitors.

Although the surrounding area has many rural, pastoral features, including horse farms, housing developments are increasingly prevalent.

===Bodies of water===
Inside of the city of Upper Marlboro, there are three bodies of water: Federal Spring Branch, Western Branch [[Patuxent River]], and School House Pond. Federal Spring Branch flows into the Western Branch Patuxent River nearby Main Street, Upper Marlboro. School House Pond is to the south of the other two bodies.

====Federal Spring Branch====
The branch is approximately two miles long and starts approximately one mile to the west of Upper Marlboro. It splits into four unnamed steams, that join later on. The only bridge over the branch is Old Marlboro Pike, or [[Maryland Route 725]].<ref>{{cite web|url=https://www.topozone.com/maryland/prince-georges-md/stream/federal-spring-branch/|title=Federal Spring Branch Topo Map, Prince George's County MD (Bristol Area)|website=topozone.com|access-date=May 15, 2018|archive-date=November 12, 2023|archive-url=https://web.archive.org/web/20231112012146/https://www.topozone.com/maryland/prince-georges-md/stream/federal-spring-branch/|url-status=live}}</ref>

====School House Pond====
School House Pond is a small pond north of Main Street, yet south of Federal Spring Branch. The pond is 12 acres in size, with a 0.75-mile boardwalk around the edge. There is also a walking trail through the small forested area north of the pond. The largest attraction at the pond is fishing. The pond is restocked with 800 [[trout]] a year.

====Western Branch Patuxent River====
The Western Branch Patuxent River is one of the largest tributaries of the [[Patuxent River]]. Its flow starts in [[Woodmore]], Maryland, and enters the Patuxent River just a few miles south of Upper Marlboro. The river's largest tributary south of Upper Marlboro is [[Collington Branch]], which flows into the Western Branch Patuxent River just before entering the Patuxent.
