'''Calvert County''' is a [[Counties of the United States|county]] located in the [[U.S. state]] of [[Maryland]]. As of the [[2020 United States census]], the population was 92,783.<ref name=":0">{{cite web|title=Census - Geography Profile: Calvert County, Maryland|url=https://data.census.gov/profile/Calvert_County,_Maryland?g=0500000US24009|access-date=December 22, 2022|publisher=[[United States Census Bureau]]}}</ref> Its [[county seat]] is [[Prince Frederick, Maryland|Prince Frederick]].<ref name="GR6">{{cite web|url=http://www.naco.org/Counties/Pages/FindACounty.aspx |access-date=June 7, 2011 |title=Find a County |publisher=National Association of Counties |url-status=dead |archive-url=https://web.archive.org/web/20110531210815/http://www.naco.org/Counties/Pages/FindACounty.aspx |archive-date=May 31, 2011}}</ref> The county's name is derived from the family name of the [[Baron Baltimore|Barons of Baltimore]], the proprietors of the English [[Province of Maryland|Colony of Maryland]]. Calvert County is included in the [[Washington metropolitan area|Washington–Arlington–Alexandria, DC–VA–MD–WV Metropolitan Statistical Area]]. It occupies the [[Calvert Peninsula]], which is bordered on the east by [[Chesapeake Bay]] and on the west by the [[Patuxent River]]. The county has one of the highest median household incomes in the United States.<ref>[[Highest-income counties in the United States#Counties with populations 65,000-250,000]]</ref> It is one of the older counties in Maryland, after [[St. Mary's County, Maryland|St. Mary's]], [[Kent County, Maryland|Kent County]] and [[Anne Arundel County, Maryland|Anne Arundel counties]]. The county is part of the [[Southern Maryland]] region of the state.

==History==
===Early history===
In 1608, [[John Smith (explorer)|Captain John Smith]] was the first European to sail past Calvert County while exploring the western shore of the Chesapeake Bay. On his map, he accurately represented the Patuxent River as well as several Native-American villages. The area was described as wooded and had been occupied by the [[Patuxent people]] who were overall peaceful to the early Europeans. Their diet was composed of fish from the river and corn cultivated in man-made clearings with a supplement of game from the forests. These clearings were very desirable and conflict occurred when the settlers attempted to seize these areas from the Native Americans. [[Leonard Calvert]], the first Governor of the Maryland, organized troops of armed men in 1639 to protect the settlers.<ref name="History Stein">Stein Charles Francis. 1977-1976. A History of Calvert County Maryland. 3d ed. Baltimore Md: Published by the author in cooperation with the Calvert County Historical Society</ref>

The first written mention of European settlers on the northern shore of the Patuxent River is found in the records of the Maryland Assembly in 1642. A Henry Bishop "stood up in the Assembly and exhibited himself as a [[Burgess (title)|Burgess]] of St. Leonard's and pleaded that it be acknowledged as a [[Hundred (county division)|Hundred]]" near St. Leonard's Creek. This shows that European settlement along the river and its tributaries had been taking place for several years already.<ref name="History Stein" />

By 1646, the colonists had spread all along the Patuxent River and up the Bay side of Calvert County. Most of the transportation of goods and people took place on the water as the land was occupied by dense forests. Large creeks were navigated by sailing boats and plantations used their wharves to ship good. Ferry services were setup across the river and the bay with rates fixed by law.<ref name="History Stein" />

===Creation of Charles County===
The county was originally named '''Charles County''' (much larger and unrelated to the present-day [[Charles County, Maryland|Charles County]])<ref name="arnett">Arnett, pp 92, discusses role of [[Robert Brooke, Sr.]]</ref>  in 1650 when [[Cecil Calvert, 2nd Baron Baltimore]] established it with [[Robert Brooke Sr.|Robert Brooke]] as its "Commander". It was named after [[Charles I of England]]. At the time, the new county included the current area of Calvert County as well as the southern and western shores of the Patuxent River up to its headwaters. The county seat was called Calverton (sometimes called Battle Town) and was located on the north shore at the mouth of Battle Creek until 1725.<ref name="African-Americans Calvert">African-Americans in Calvert County - A Brief History https://www.calvertcountymd.gov/DocumentCenter/View/6107/African-American-History?bidId=</ref> In 1658, the county was renamed Calvert County.<ref>Maryland Online Encyclopedia ''Calvert County''</ref> It also included all of [[Prince George's County, Maryland|Prince George's County]] and parts of [[Montgomery County, Maryland|Montgomery County]].<ref name="History Stein" />

Puritans coming from Virginia had settled in [[Anne Arundel County, Maryland|Anne Arundel County]] and overflowed into Calvert County. All new settlers in Maryland were required to take an oath of allegiance to Lord Baltimore per the "Conditions of Plantation". This was a major point of tension between the Puritan settlers and Lord Baltimore. The [[Wars of the Three Kingdoms|civil war]] was ongoing in Britain where the Puritans had gained control. [[Oliver Cromwell]] dismissed Parliament there and assumed the role of Lord Protector. In 1652, he sent a force of 750 men to subdue the plantations of the Chesapeake Bay under the new government. Virginia and Maryland surrendered to the Puritans and Robert Brooke cooperated with the Puritans.<ref name="History Stein" />

On July 3, 1654, Lord Baltimore abolished Charles County and removed all authority from Brooke. He re-established the county as '''Calvert County''' with the same territory. However, the Puritan Assembly was in power and changed the name to '''Patuxent County''' on October 20, 1654, after the Patuxent River and to remove any connection with the Calvert family. The county kept this name under the Puritan regime until 1658 when the name of Calvert County was restored.<ref name="History Stein" />

According to the local "Trail of Souls Project",<ref>{{Cite web |title=Trail of Souls Project {{!}} Middleham and St. Peter's Parish |url=http://www.middlehamandstpeters.org/about-us/our-history/trail-of-souls-project/ |access-date=January 9, 2024 |website=www.middlehamandstpeters.org}}</ref> in 1860 there were 4,609 enslaved people, 1,841 free people of color for a total county population of 10,000 people.<ref name="Trail of Souls Project">Trail of Souls at Middleham and St. Peters: Uncovering the History of Slavery in Southern Calvert County http://ccd7fae51be7d3e9b11f-7a238febfb6dc77c392de145b8e7a053.r7.cf2.rackcdn.com/uploaded/t/0e4716290_1449286479_trail-of-souls-full-story.pdf#page=5</ref>

Once made up primarily of farms and tobacco fields, the county's agriculture transformed in the mid-1990s. The prices for tobacco were declining. The State of Maryland instituted the Tobacco Buyout program which offered farmers to transition to different crops and away from tobacco. 195 contracts were signed between Calvert county farmers and property owners and The Southern Maryland Agricultural Development Commission. The funds were used for infrastructure and equipment upgrades. Today the county produces fruits, vegetables, meat as well as other crops.<ref>Calvert County Agriculture - https://www.calvertag.com/3153/Agriculture</ref>

The county has become a fast-growing [[exurb]]an neighbor of [[Washington, D.C.|Washington]]. Many home prices have nearly quadrupled in the past decade, with many four-bedroom homes in the northern half of the county averaging over $1,000,000. The popular weekend resort towns of [[Solomons, Maryland|Solomons]], [[Chesapeake Beach, Maryland|Chesapeake Beach]], and [[North Beach, Maryland|North Beach]] are notable.

The county has numerous properties on the [[National Register of Historic Places listings in Calvert County, Maryland|National Register of Historic Places]].<ref name="nris">{{NRISref|2008a}}</ref>

In the early 19th Century, in the contests between the Hamiltonian [[Federalist Party|Federalist]] and Jeffersonian [[Democratic-Republican Party|Democratic-Republican]] parties of the [[First Party System]], it backed the Federalists four out of seven times, only going for the Democratic-Republicans in their greatest landslides of [[1804 United States presidential election|1804]] and [[1816 United States presidential election|1816]] as well as the [[1820 United States presidential election|1820]] election in which President [[James Monroe]] ran effectively unopposed.<ref>{{Cite web|title=County Project (WIP)|url=https://docs.google.com/spreadsheets/d/1qW_PF3ONwrR0pp6tZpxvcin0GN5O2VOZfBrtJNhjv3Y/edit?usp=sharing&usp=embed_facebook|access-date=September 1, 2021|website=Google Docs|language=en-US}}</ref>

In the [[1824 United States presidential election|1824 election]] which began the second party system, the people of Calvert County voted for [[John Quincy Adams]] over [[Andrew Jackson]], who would go on to help found the Democratic Party before the [[1828 United States presidential election|1828]] election. Up until the [[American Civil War|Civil War]], Calvert County voted only for the candidates of the [[Whig Party (United States)|Whig Party]], the Democrat's primary opposition. After that party's dissolution in the early 1850s, it supported the Nativist [[Know Nothing|Know-Nothing]] party in [[1856 United States presidential election|1856]] and the largely Whiggish [[Constitutional Union Party (United States)|Constitutional Union]] party in [[1860 United States presidential election|1860]].

In the Civil War election of [[1864 United States presidential election|1864]], Calvert swung sharply along with the rest of southern Maryland to give over 90% of the vote to Democratic challenger [[George B. McClellan|George McClellan]], and again to the Democratic standard-bearer [[Horatio Seymour]] four years later. The brief Democratic era was likely due to strong Confederate sympathy in Southern Maryland.<ref>{{Cite web|date=February 1, 2016|title=Maryland in the Civil War|url=https://www.civilwarmed.org/maryland/|access-date=September 1, 2021|publisher=National Museum of Civil War Medicine}}</ref>

In Presidential elections, Calvert County has historically and at present leaned strongly towards the Republican Party. It was won by that party in every election from 1884 to 1936 – with the sequence broken in 1940 due to local support for [[Franklin Delano Roosevelt]]'s efforts at helping Britain in [[World War II]]<ref>Menendez, Albert J.; ''The Geography of Presidential Elections in the United States, 1868–2004'', pp. 67–68 {{ISBN|0786422173}}</ref> – and in modern times no Democratic presidential nominee has won Calvert County since [[Jimmy Carter]] did so in 1976.

Since then, Calvert County has remained mostly aligned with the Republican Party. It briefly turned in favor of the Democrats in the [[Dealignment|dealigned]] 1960s and 70s, after which it became a Republican stronghold in the 1980s. In modern elections, it leans Republican though Democrats have gained votes. President [[Joe Biden]] came only 5% from winning the county in [[2020 United States presidential election|2020]],<ref>{{Cite web |title=2020 Election Results |url=https://elections.maryland.gov/elections/2020/results/general/gen_results_2020_4_by_county_05-1.html |access-date=January 9, 2024 |website=elections.maryland.gov}}</ref> the closest any Democrat has come since Jimmy Carter carried it in 1976.

It is part of the [[Maryland's 5th congressional district|5th Congressional District]], along with much of Southern Maryland. The current representative is Democratic former House Majority Leader [[Steny Hoyer]].

According to the [[U.S. Census Bureau]], the county has a total area of {{convert|345|sqmi}}, of which {{convert|213|sqmi}} is land and {{convert|132|sqmi}} (38%) is water.<ref name="GR1">{{cite web|url=https://www.census.gov/geo/maps-data/data/docs/gazetteer/counties_list_24.txt |archive-url=https://web.archive.org/web/20140913171515/http://www.census.gov/geo/maps-data/data/docs/gazetteer/counties_list_24.txt |url-status=dead |archive-date=September 13, 2014 |publisher=United States Census Bureau |access-date=September 12, 2014 |date=August 22, 2012 |title=2010 Census Gazetteer Files}}</ref> It is the smallest county in Maryland by land area and third-smallest by total area. The county also includes [[List of islands of Maryland|five islands]]: [[Solomons, Maryland|Solomons Island]], [[Broomes Island, Maryland|Broomes Island]], Buzzard Island,<ref>{{Cite web|title=Collection: Harwood Family Buzzard Island papers {{!}} Archival Collections|url=https://archives.lib.umd.edu/repositories/2/resources/1284|access-date=September 11, 2020|website=archives.lib.umd.edu}}</ref> Hog Island, and Molly's Leg.

The county's coast along the Chesapeake Bay is a long, relatively smooth [[Bight (geography)|bight]], a feature that is unique in the Chesapeake Bay.

===Geology===
A geological formation spanning across Maryland, [[Virginia]], and [[Delaware]] is named after the county: the [[Calvert Formation]]. It is visible within the [[Calvert Cliffs State Park]] where it is exposed in cliffs. Located on the western shore of the county, Calvert Cliffs are famous for their fossil deposits and are a popular collecting location of marine vertebrates, shark teeth, birds as well as fresh water and marine turtles and tortoises. Some crocodile teeth have also been found which indicates that they may have been nesting in the sands at the time the formation was created.<ref>Calvert Cliffs Fossils - Maryland Geological Survey http://www.mgs.md.gov/geology/fossils/calvert_cliffs_fs.html</ref>

The county landscape is composed of three platforms: the Talbot Terrace, the Wicomico Terrace, and the Sunderland Terrace (also known as the Ridge). These terraces correspond to three periods where the water level rose and later fell, leaving sand deposits. The oldest was created during the [[Miocene]] Age when the entire county peninsula found itself underwater. Marine deposits, clay, and mud containing sea shells and fossils were left behind leading to what we see at Calvert Cliffs today after the sea receded and the waves started erroring the deposit. These three terraces are visible in various parts of the county and are most obvious on the Bay side of the county where they rise to a height of 100 feet.<ref name="History Stein" />

===Climate===
Calvert County lies in the [[humid subtropical climate]] zone (''Cfa'') in the [[Köppen climate classification]], with hot, humid summers and mild to chilly winters with plentiful precipitation year-round. In the [[Trewartha climate classification]] the county is classified as [[oceanic climate|oceanic]] (''Do'') except in the extreme south which is ''Cf''. Its proximity to the [[Chesapeake Bay]] has a moderating effect on temperatures compared with locales further inland. Average monthly temperatures in Prince Frederick range from 35.9&nbsp;°F in January to 77.9&nbsp;°F in July.<ref>{{cite web | url=https://prism.oregonstate.edu/explorer/ | title=PRISM Climate Group at Oregon State University }}</ref>

==Transportation==
[[File:2016-07-20 17 33 07 View south along Maryland State Route 2 and Maryland State Route 4 (Solomons Island Road) just south of Southern Maryland Boulevard in Calvert County, Maryland.jpg|thumb|right|MD 2/MD 4 southbound in Calvert County]]
The main artery serving Calvert County is [[Maryland Route 4]] (which begins in [[Washington, D.C.]] as [[Pennsylvania Avenue (Washington, D.C.)|Pennsylvania Avenue]] before crossing into [[Prince George's County, Maryland]] and [[Anne Arundel County, Maryland]]). Route 4 in Calvert County begins at the very northern tip of the county at Lyons Creek, approximately 3 miles north of [[Dunkirk, Maryland|Dunkirk]]. At [[Sunderland, Maryland|Sunderland]], Route 4 meets [[Maryland Route 2]] (traveling south as a two-lane road from [[Annapolis, Maryland|Annapolis]]) and the two roads merge as Maryland Route 2–4. Route 2-4 continues south through [[Prince Frederick, Maryland|Prince Frederick]], [[St. Leonard, Maryland|St. Leonard]] and [[Lusby, Maryland|Lusby]]. At [[Solomons, Maryland|Solomons]], Routes 2 and 4 split again, with Route 2 heading towards downtown [[Solomons, Maryland|Solomons]] and Route 4 crossing the [[Patuxent River]] at the [[Governor Thomas Johnson Bridge]] into [[St. Mary's County, Maryland|St. Mary's County]].

Route 2-4 is designated Solomons Island Road throughout much of the county, with the section south of [[Prince Frederick, Maryland|Prince Frederick]] being recently renamed Louis Goldstein Highway in memory of [[Louis L. Goldstein]], the former [[comptroller]] of [[Maryland]] and Calvert County resident.

In the 1970s and 1980s, Route 2-4 underwent an extensive expansion project, with the formerly two-lane road becoming a four-lane dual highway. Certain portions of the highway were re-aligned, with the former roadway becoming [[Maryland Route 765]]. The final portion of the dualized Route 2-4 between [[St. Leonard, Maryland|St. Leonard]] and [[Solomons, Maryland|Solomons]] was completed in 1988. In 2009, a portion of Route 2–4 in Prince Frederick was expanded to three lanes, along with sidewalks added.

Other major roadways in Calvert County include:
* [[Maryland Route 231]], which travels west from [[Prince Frederick, Maryland|Prince Frederick]] to the [[Patuxent River]], ultimately crossing the river at the [[Benedict Bridge]] into [[Charles County, Maryland|Charles County]].
* [[Maryland Route 260]], which starts at an overpass interchange at the Calvert-Anne Arundel border and travels southeast to [[Chesapeake Beach, Maryland|Chesapeake Beach]]. A portion of Route 260 is a four-lane dual highway.

The "town center" designation means while these communities may not have incorporated central governments, they do have specified boundaries surrounding the central business and residential areas for [[zoning]] purposes. The reason behind the "town center" designation is to cluster new development within established areas with existing infrastructure, thus discouraging [[urban sprawl]]. The implementation of the "town center" concept in Calvert County over the past two decades has for the most part been successful in preserving rural and agricultural areas outside the designated "town centers", and stands as a key example of the [[smart growth]] planning strategy.<ref>{{cite web|url=http://www.ecalvert.com/content/business/commercialrealestate/search/zoning_info.asp |title=Zoning Information |publisher=Calvert County Department of Economic Development |access-date=October 6, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20081011123941/http://www.ecalvert.com/content/business/commercialrealestate/search/zoning_info.asp |archive-date=October 11, 2008}}</ref><ref>{{cite web|url=http://www.co.cal.md.us/assets/Planning_Zoning/Slideshows/March-6-07BOCC-UpdatesToTCMP.pdf|title=Architectural Review in Calvert County|publisher=Calvert County Planning and Zoning|date=March 6, 2007|access-date=October 6, 2007|url-status=dead|archive-url=https://web.archive.org/web/20071128033334/http://www.co.cal.md.us/assets/Planning_Zoning/Slideshows/March-6-07BOCC-UpdatesToTCMP.pdf|archive-date=November 28, 2007}}</ref>
