History

[edit]

In 1608 the area was inhabited byMassawomecks andSusquehannocks.[3]: 16–17  The first European to see the area wasJohn Smith in 1608 when he traveled up theChesapeake Bay fromJamestown.[3]: 14–15  In 1652, the English and Susquehannocks signed atreaty at what is nowAnnapolis for the area now called Harford County.[3]: 24 

Harford County was formed on March 22, 1774, from the eastern part ofBaltimore County with a population of 13,000 people.[3]: 13, 60  On March 22, 1775, Harford County hosted the signers of theBush Declaration, a precursor document to theAmerican Revolution.[3]: 102  On January 22, 1782, Bel Air became the county seat.[3]: 67 

Havre de Grace, a city incorporated in 1785 within Harford County, was once under consideration to be thecapital of the United States rather than Washington, D.C.[3]: 250  It was favored for its strategic location at the top of theChesapeake Bay; this location would facilitatetrade while being secure in time of war.[4] Today, the waterways around Havre de Grace have become adversely affected by silt runoff, which is one of the primary environmental issues of Harford County.[5] While today the site is a MarylandNational Guard military reservation, the land was used as the Havre de Grace Racetrack where racehorseMan o' War ran in 1919 and 1920.[6]

During the 1900s the Bata Shoe Company employed numerous Eastern Europeanrefugees at theBelcamp factory.[7]: 4  In the 1940s theSusquehanna River tributaryBroad Creek was dammed to form the 55 acres (0.22 km2) at what is now theBroad Creek Memorial Scout Reservation.[8] In June 1972Hurricane Agnes overflowed the dam and flooded areas in many states.[9] On theCounty Health Rankings & Roadmaps by theRobert Wood Johnson Foundation with theUniversity of Wisconsin Population Health Institute, "prior to the 2016 report ... Harford's yearly rankings[10] typically fell between ninth and 10th place, primarily because of the percentage of county residents who were obese or who smoked."[11] Scenes fromTuck Everlasting,From Within, andHouse of Cards were all filmed in Harford County.[citation needed]

In 2011 the Office of National Drug Control Policy deemed Harford County a designated High Intensity Drug Trafficking Area.[12]

The county was named forHenry Harford (c. 1759–1834), the illegitimate son ofFrederick Calvert, 6th Baron Baltimore. Henry Harford was born to Calvert's mistress, Hester Whelan, whose residence still stands as part of a private residence on Jarretsville Pike, in Phoenix, Maryland. Harford served as the last Proprietary Governor ofMaryland but, because of his illegitimacy, did not inherit his father's title.[3]: 53  There are 79 properties and districts listed on the National Register in the county, including oneNational Historic Landmark calledSion Hill.[13]

Environmental history

[edit]

Harford County has environmental issues in three major areas:land use,water pollution/urban runoff, andsoil contamination/groundwater contamination.

As the county sits at the headwaters of theChesapeake Bay along theSusquehanna River, it plays a key role in controllingsediment andfertilizerrunoff into the bay as well as fosteringsubmerged aquatic vegetation (SAV) regrowth. The county has had to balance the needs of land owners to practice agriculture and/or pave land (creatingimpervious surfaces) with effects of runoff into the bay.

Harford County has been burdened by soil contamination and groundwater contamination since the creation of theAberdeen Proving Ground in 1917. The military installation performs research for theU.S. Army, including weapons testing, and has released various chemical agents into soil and groundwater, includingmustard gas andperchlorate. The bordering towns ofAberdeen,Edgewood andJoppatowne have been affected by this contamination.[14][15]

Aberdeen Proving Ground contains threeSuperfund priority sites as of 2006[update]. Groundwater contamination byMTBE, a mandatorygasoline additive, has also affectedFallston.[16][17]

Entering Harford County, Maryland from Baltimore County, Maryland

Harford County also faces controversy from residents living nearScarboro Landfill and Harford Waste Disposal Center, the only municipallandfill. The landfill, approved to triple in size in 2007, is the subject of complaints by neighbors of operating violations, such as large areas of open trash and blown litter;leachate breaks which contaminate area residential wells and flow intoDeer Creek, a tributary of the Susquehanna River; and increased health problems.[citation needed]

Harford County is, like thePennsylvania Dutch Country to its north, a strongly Republican region. No Democratic presidential candidate has carried Harford County sinceLyndon Johnson’s landslide of 1964, although recent trends have shown the county voting less Republican over the past few elections. In the period before World War II Harford leaned strongly Democratic as it had sizeable Confederate sympathies,[23] but during and sinceWorld War II the county has turned away from its traditional allegiances.[citation needed]

Harford County was granted acharter form ofgovernment in 1972. This means that the county is run by a County Executive and Council President, both elected at large, as well as Council Members, elected from districts. Currently, there are six districts in Harford County. Also elected at large is the Sheriff, who runs theHarford County Sheriff's Office, the State's Attorney, who prosecutes all crimes in the county, the Register of Wills, and the Clerk of the Circuit Court.
