In 1608 the area was settled by Massawomecks and Susquehannocks.:16–17 The first European to see the area was John Smith in 1608 when he traveled up the Chesapeake Bay from Jamestown.:14–15 In 1652, the English and Susquehannocks signed a treaty at what is now Annapolis for the area now called Harford County.:24
Harford County was formed on March 22, 1774 from the eastern part of Baltimore County with a population of 13,000 people.:13,60 On March 22, 1775 Harford County hosted the signers of the Bush Declaration, a precursor document to the American Revolution.:102 On January 22, 1782 Bel Air became the county seat.:67
After supposedly marrying Mary Ann Holmes in 1821 Junius Brutus Booth Sr. moved to the county into a log cabin before building Tudor Hall in 1847. Junius Brutus Booth Sr. "was followed as a marvel. Mention of his name stirred an enthusiasm no other could awaken.":149 Junius Brutus Booth Jr. was born to the couple in Bel Air, Harford County, Maryland in 1821 before managing the Boston Theatre, Walnut Street Theatre, Winter Garden Theatre, and Booth's Theatre where his younger brother Edwin was the star attraction. Though a relatively undistinguished actor, Junius Jr. was highly regarded for his performances as King John and Cassius in Julius Caesar, which he performed with Edwin as Brutus and John Wilkes as Mark Antony in 1864. He married Agnes Land Perry in 1867. He retired in 1881 to Masconomo House in Manchester-by-the-Sea, Massachusetts, where he died on September 17, 1883. Edwin Booth was also born in Bel Air but in 1833 and later toured America and Europe performing plays by Shakespeare before founding Booth's Theatre in New York in 1869. Edwin was a Unionist.
Born in the same log cabin but in 1838 John Wilkes Booth made his stage debut at age 17 on August 14, 1855 in the supporting role of the Earl of Richmond in Richard III at Baltimore's Charles Street Theatre. Some of the more known theaters that he acted for include John T. Ford's Holliday Street Theater in Baltimore, Arch Street Theatre in Philadelphia, and the Richmond Theatre. Of all Shakespearean characters his favorite role was Brutus the slayer of a tyrant. Some critics called him "the handsomest man in America," a "natural genius", and praised his "astonishing memory" while others gave mixed reviews of his acting. Historian Benjamin Platt Thomas wrote that Booth "won celebrity with theater-goers by his romantic personal attraction."
Author Gene Smith wrote that Booth's acting may not have been as precise as his brother Edwin's, but his strikingly handsome appearance enthralled women. As the 1850s drew to a close, Booth was becoming wealthy as an actor, earning $20,000 a year (equivalent to about $569,000 today). Despite the acting fame of the entire Booth family, John Wilkes Booth will always be most known for assassinating Abraham Lincoln.
Havre de Grace, a city incorporated in 1785 within Harford County, was once under consideration to be the capital of the United States rather than Washington, D.C.:250 It was favored for its strategic location at the top of the Chesapeake Bay; this location would facilitate trade while being secure in time of war. 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. While today the site is a Maryland National Guard military reservation, the land was used as the Havre de Grace Racetrack where racehorse Man o' War ran in 1919 and 1920.
During the 1900s the Bata Shoe Company employed numerous Eastern European refugees at the Belcamp factory.:4 In the 1940s the Susquehanna River tributary Broad Creek was dammed to form the 55 acres (0.22 km2) at what is now the Broad Creek Memorial Scout Reservation. In June 1972 Hurricane Agnes overflowed the dam and flooded areas in many states. On the County Health Rankings & Roadmaps by the Robert Wood Johnson Foundation with the University of Wisconsin Population Health Institute, "prior to the 2016 report ... Harford's yearly rankings typically fell between ninth and 10th place, primarily because of the percentage of county residents who were obese or who smoked." Scenes from Tuck Everlasting, From Within, and House of Cards were all filmed in Harford County.
In 2011 the Office of National Drug Control Policy deemed Harford County a designated High Intensity Drug Trafficking Area.
The county was named for Henry Harford (ca. 1759–1834), the illegitimate son of Frederick 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 of Maryland but, because of his illegitimacy, did not inherit his father's title.:53 There are 79 properties and districts listed on the National Register in the county, including one National Historic Landmark called Sion Hill.
As the county sits at the headwaters of the Chesapeake Bay along the Susquehanna River, it plays a key role in controlling sediment and fertilizer runoff into the bay as well as fostering submerged aquatic vegetation (SAV) regrowth. The county has had to balance the needs of land owners to practice agriculture and/or pave land (creating impervious surfaces) with effects of runoff into the bay.
Harford County has been burdened by soil contamination and groundwater contamination since the creation of the Aberdeen Proving Ground. The military installation performs research for the U.S. Army and has released various chemical agents into soil and groundwater, including mustard gas and perchlorate. The bordering towns of Aberdeen, Edgewood and Joppatowne have been affected by this contamination. Aberdeen Proving Ground contains three Superfund priority sites as of 2006[update]. Groundwater contamination by MTBE, a mandatory gasoline additive, has also affected Fallston.
Harford County also faces controversy from residents living near Scarboro Landfill and Harford Waste Disposal Center, the only municipal landfill. 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 into Deer Creek, a tributary of the Susquehanna River, and increased health problems.
Harford County straddles the border between the rolling hills of the Piedmont Plateau and the flatlands of the Atlantic Coastal Plain along the Chesapeake Bay and its tributaries. The county's development is a mix of rural and suburban, with denser development in the larger towns of Aberdeen and Bel Air and along Route 40 and other major arteries leading out of Baltimore. The highest elevations are in the north and northwest of the county, reaching 805 ft. near the Pennsylvania border in the county's northwestern corner. The lowest elevation is sea level along the Chesapeake Bay.

Politics and governmentEdit
Harford County is, like the Pennsylvania Dutch Country to its north, a strongly Republican region. No Democratic presidential candidate has carried Harford County since Lyndon Johnson’s landslide of 1964. In the period before World War II Harford leaned strongly Democratic as it had sizeable Confederate sympathies, but during and since the Second World War the county has turned away from its traditional allegiances.
