Anne Arundel County was originally part ofSt. Mary's County, the province's first erected county in the southern portion of theProvince of Maryland, which had first been established by arriving settlers in 1634. In 1650, the year after Lady Ann Arundell's death, the county separated from St. Mary's and "erected" into its own jurisdiction and became thethird of the 23 Maryland counties. It was composed of thehundreds of Town Neck, Middle Neck, Broad Neck, South River, West River, and Herring Creek.[3] Between 1654 and 1658, the county was known as "Providence" by many of its early settlers.[4]
On March 25, 1655, after theEnglish Civil War, (1642–1651), in Europe, theBattle of the Severn, the first naval colonial battle ever fought in North America, was fought in Anne Arundel County on theSevern River betweenPuritan forces supporting theCommonwealth of England and forces loyal to Lord Proprietor Cecilius Calvert. The Commonwealth forces under Captain William Fuller were victorious.[5]
In 1692, the Church of England, also known as the Anglican Church, became the established church of the Province of Maryland through an Act of the General Assembly. Ten counties had been established in the colony, and those counties were divided into 30 parishes, with vestrymen appointed within each. Ann Arrundell County was divided into four parishes: Herring Creek, South River, Middle Neck, and Broad Neck.[6]
Between 1694 and 1695, the provincial capital of Maryland was moved fromSt. Mary's City along the northern shore of thePotomac River across from the southern colonial border with theProvince of Virginia in St. Mary's County farther north along the western shore of theChesapeake Bay, midway in the colony to Annapolis in Anne Arundel County. Prior to the move, Annapolis was known as "Providence".[7]
On May 22, 1830, the inaugural horse-drawn train of theBaltimore and Ohio Railroad travelled the 13 miles (21 km) of the newly completed track fromMount Clare Station in southwesternBaltimore toEllicott Mills (now Ellicott City), then in the Western or Howard District (nowHoward County) of Anne Arundel County. This was the first regular railroad passenger service in the United States.[disputed –discuss][9] In 1831, land west of the railroad was considered the Howard District of Anne Arundel County. In 1851, the Howard District was broken off to formHoward County, now the 21st county in Maryland (of 23).[10]
According to theU.S. Census Bureau, the county has a total area of 588 sq mi (1,520 km2), of which 173 sq mi (450 km2) (29%) is covered by water.[12] Anne Arundel County is located to the south ofBaltimore.[13]
Most of the county's borders are defined by water. To the east lies the western shore of theChesapeake Bay, and numerous tidal tributaries of the bay indent the shoreline, the various rivers, creeks, streams, inlets forming prominentpeninsulas, also known as "necks" (as further south in Virginia). The largest of these tributaries include (from north to south), theMagothy River,Severn River,South River, and theWest River. Further south, the upperPatuxent River forms the border of Anne Arundel withPrince George's County to the west.Deep Run forms part of the northwestern border withHoward County, andLyons Creek forms part of the southern border withCalvert County. ThePatapsco River to the north is the border withBaltimore County, but the communities and areas ofBrooklyn andCurtis Bay neighborhoods (and adjacent Fairfield, Wagner's Point [also known as East Brooklyn], Arundel Cove [off of Curtis Creek], and Hawkins Point), lying south of thePatapsco River were annexed from Anne Arundel County toBaltimore in the third major annexation of January 1919.[14]
Anne Arundel County originally included all of the land between the Patuxent River and the Patapsco River (mainstem and South Branch) upstream to their headwaters onParr's Ridge. The northwestern section of this long tract later became Howard County, with the border between the two running very close to theAtlantic Seaboard fall line. As a result, Anne Arundel County lies almost entirely within theAtlantic Coastal Plain, while Howard County is almost entirely within thePiedmont province.[citation needed]
Elevations in Anne Arundel County range from sea level at the Chesapeake and tidal tributaries to about 300 feet (91 m) in western areas near the fall line.[15] The terrain is mostly flat or gently rolling, but more dramatic banks and bluffs can be found where waterways cut through areas of higher elevation.[citation needed]
With the exception of the very limited extent of Piedmont underlain byPrecambrian to earlyPaleozoicmetamorphic rock, all of the county is underlain by thick deposits of gravel, sand, silt, and clay dating from the earlyCretaceous toHolocene times.[16] Most of these sediments are unconsolidated but include local formations of sandstone, especially in thePasadena area.[17]
Anne Arundel County has ahumid subtropical climate, with hot summers and cool winters. Annual precipitation averages around 40 in (100 cm) per year throughout the county, with a fairly even distribution throughout the year. Annual snowfall totals around 20.1 in (51 cm) on average at BWI Airport, which has an elevation of 156 ft (47.5 m) above sea level.[18] Slightly colder winter temperatures and higher snowfall are experienced at the higher elevations, with slightly lower snowfall closer to sea level.[19] According to the most recentUSDA Hardiness zone maps, the lowland areas of the county fall into Zone 8a, with an expected annual minimum temperatures of 10 to 15 °F (−12 to −9 °C), while higher elevation and inland areas fall into Zone 7b, with expected annual minima of 5 to 10 °F (−15 to −12 °C).[20]
Anne Arundel County has had a charter government since 1965. The government consists of a county executive and a seven-member county council. These members are elected in the same years Maryland conducts its gubernatorial and legislative elections, and may serve a maximum of two consecutive terms.[citation needed]
TheDemocrats have the most registered voters in the county, but the large number ofRepublican-leaning independents means Republicans win more county-wide elections than in other mostly suburban counties in Maryland, but Democrats are the dominant party in Annapolis city elections. In the2016 presidential election, Anne Arundel County voted forHillary Clinton overDonald Trump by 6,016 votes.[21] It was the first time that the county had supported a Democrat for president since1964. Four years later, Joe Biden won the county by nearly 15%, the largest margin of victory for a Democrat in the county since the landslide election ofLyndon Johnson in the1964 presidential election.[22]
Anne Arundel County is one of six "reverse pivot counties", counties that voted Republican in 2008 and 2012 before voting Democratic in 2016 onward.[23]
Thecounty executive oversees the executive branch of the county government, which consists of a number of offices and departments. The executive branch is charged with implementing County law and overseeing the operation of the county government.
The County Council, as the legislative branch, adopts ordinances and resolutions, and has all of the county's legislative powers. The most recent county election occurred November 8, 2022.[26]
