, and Kent Counties. In 1674, a proclamation of the Proprietor established the then-extensive boundary lines for old Baltimore County. Over the next century, various segments of the old county were sliced off as population and settlements increased in fringe regions. A portion of northeastern Baltimore County, as well as a portion of northwestern Kent County, was split off to create Cecil County. In 1748, a portion of western Baltimore County, as well as a portion of Prince George's County to the south, were split off to create Frederick County. In 1773, Harford County to the east was split off, and in 1837 another part of western Baltimore County was combined with a part of eastern Frederick County to create Carroll County.

in 1727, a portion of the county's northwestern area was designated in 1838 as the "Western District" or "Howard District" of Arundel and in 1851 was officially separated to form Howard County. Prior to 1674, Baltimore County court sessions were held in private residences, according to sketchy documentary evidence. In 1674, the General Assembly passed "An Act for erecting a Court-house and Prison in each County within this Province". The site of the courthouse, jail and county seat for Baltimore County was evidently "Old Baltimore" near the Bush River on land that in 1773 became part of Harford County. The exact location of Old Baltimore is Chilbury Point on the north side of the Bush River owned by the Garrison of the present-day

Christopher Goodwin & Associates (Goodwin). Goodwin first performed historical and archival work and coordinated with existing landscape features to locate the site of Old Baltimore. APG's Explosive Ordnance Disposal of Army personnel defused any unexploded ordnance. In 1997–1998. Goodwin dug 420 test pits, uncovering artifacts including a King Charles II farthing coin, and French and English gun flints. An unearthed brick foundation proved to be the remains of the tavern owned by colonist James Phillips. Another prominent landholder in Old Baltimore was William Osbourne, who operated the ferry across the Bush River. In 1683, the Maryland General Assembly passed "An Act for Advancement of Trade" to "establish towns, ports, and places of trade, within the province." One of the towns established by the act was "on Bush River, on Town Land, near the Court-House". The courthouse on the Bush River referenced in the 1683 Act was in all likelihood the one created by the 1674 Act. "Old Baltimore" was in existence as early as 1674, but no documents describe what may have preceded it. By 1695, the "Old Baltimore" courthouse had evidently been abandoned. County justices put the site up for sale. Apparently a new courthouse at "Simm's Choice" on the Baltimore County side of Little Gunpowder Falls had been under construction since 1692.


18th century

In 1700, builder Michael Judd sold it to the county justices. This change of location, away from the Bush River area, reflects the growing economic and political importance of the Gunpowder region. During the next decade, the county seat moved to Joppa. By 1724, the legislative assembly authorized Thomas Tolley, Capt. John Taylor, Daniel Scott, Lancelot Todd, and John Stokes purchased 20 acres from "Taylor's Choice," a tract named after John Taylor. The assembly's ordinance directed that the land be divided into 40 lots with streets and alleys to accompany the courthouse and jail erected previously. By 1750, about 50 houses (including a few large two-story brick structures), a church (St. John's Anglican Parish), a courthouse, three stone warehouses, inns, taverns, stores, a public wharf and a "gallows-tree" with an "Amen Corner" with pillories and whipping posts (now located northeast of the City of Baltimore near present-day suburban "Joppatowne" off Harford Road) existed. A new port and wharfing site, Elkridge Landing, on the upper

and the main north-south East Coast highway for wagons and carriages. Still, later it was on Washington Boulevard (designated U.S. Route 1) by 1926. With a bit of financial pressure, and after paying for the cost of a new courthouse (300 pounds sterling), dominant business, commercial and political residents of the Town of Baltimore were able to have the Maryland General Assembly relocate the county seat to their growing port town. In 1768, following receipt of petitions for and against the relocation, the General Assembly passed an Act that moved the county seat from Joppa to Baltimore. The first courthouse was constructed in 1768 at a new Courthouse Square at present-day North Calvert Street, between East Lexington and East Fayette Streets.

In 1816, the City of Baltimore annexed from Baltimore County several parcels of land known as the "Precincts" on its west, north, east and southwest sides. The County separated from the city (which it surrounds on the east, north, and west) on July 4, 1851, as a result of the adoption of the 1851 second state constitution.

The factory and business owners in the eastern industrial communities of Canton and Highlandtown resisted and opposed annexation, but were annexed 30 years later. The last major annexation took place in 1918–1919, which again took territory from the county on all three sides (west, north, and east) and to the south for the first time from Anne Arundel County, along the south shores of the

Politics and government

Baltimore County has had a charter government since 1956. The government consists of a County Executive and a seven-member County Council. The County Executive and Council members are elected in years of gubernatorial elections. The County Executive may serve a maximum of two consecutive terms. Without incorporated cities or towns, the county government provides all local services to its residents, many of which are normally associated with city-type governmental agencies. In 1956, the County adopted an "executive-council" system of government with "at large" representatives, replacing its traditional system of an elected Board of County Commissioners. Since then it has had eleven county executives and one "acting" executive, of which ten were Democrats and two were Republicans. The former

He pleaded "no contest" to unprecedented Federal criminal charges. He was forced to resign the Vice Presidency in 1973. Politically, Baltimore County leans Democratic, but not as overwhelmingly as Baltimore City. In general, the northern portions of the county lean Republican, while the southern portion is more Democratic.


State's attorney

The Baltimore County State's Attorney is responsible for prosecuting the

Law enforcement

The Baltimore County Police Department is responsible for police services. Established in the mid-17th century, the Sheriff of Baltimore County was at first filled by county justices from 1662 to 1676. After 1676, the Court submitted three names from which the colonial governor chose a sheriff. Although terms of office initially varied, by 1692, a uniform two-year term was imposed. In 1699 a three-year term with separate commissions was adopted. The sheriff acted as the chief local representative of the proprietary government. His duties included the collection of all public taxes and after 1692, the collection of the yearly poll tax of forty pounds of tobacco for the support of the

) clergy and parishes. A sheriff received a percentage of collected monies, generally about five percent. He also received a yearly salary for duties such as reporting to the governor on affairs within the county, taking/estimating the census periodically, conveying official laws and proprietary requests to the county courts and selecting juries for court sessions. Along with enforcing all provincial laws, he posted new laws in public places. While his primary duty was to serve the Proprietor, the sheriff was aware of problems faced by poor planters and tradesmen. With taxes, yearly quit-rents and other costly expenditures, many of the poorer settlers were unable to pay their obligations when due. The sheriff often extended credit to these planters and paid their immediate obligations out of his own pocket. This lessened the impact of taxes for the poor, who repaid the sheriff after their harvests were brought in. The modern Baltimore County Sheriff's Department is responsible for security of the two major County Circuit Courts buildings and various courtrooms elsewhere as well as process and warrant service. Sheriff's Deputies are sworn police officers and share the same powers of the more recently organized County Police Department. As of 2019, the Baltimore County Sheriff is a Democrat, R. J. Fisher.

Fire Department

The Baltimore County Fire Department (B.Co.F.D.) provides fire protection, emergency medical services and emergency rescue services to the county and surrounding areas, including Baltimore City, through mutual-aid pacts with those jurisdictions. The department consists of both paid and volunteer companies that provide services to overlapping territories. Twenty-five career (paid) stations and 28 volunteer stations operate there. More than 1,000 paid personnel and more than 2,000 volunteers serve in the department. The department conducts annual fire inspections on commercial properties, fire investigation and fire prevention education activities as well as water and tactical rescue. Sworn in as fire chief on July 1, 2019, Joanne R. Rund is the first female chief to be permanently appointed to the position.

Politics

Baltimore County is somewhat of a bellwether for Maryland politics. While it leans slightly Republican compared to the state as a whole, Republicans running for statewide office must carry it solidly to win a statewide election. After going Republican in all but one presidential election from 1944 to 1988, it has voted for the Democratic candidate for president in each election since 1992. Along with neighboring Howard County, it has voted for the state-wide presidential winner in 10 straight elections, the longest such streak in the state. However, in gubernatorial elections, it has often gone Republican (1994, 1998, 2006) even as a Democratic candidate was elected governor. In the 2014 gubernatorial election Republican Larry Hogan won Baltimore County by over 20 points (59.03% to 38.89%).


Federal government

Baltimore County is represented by Republican Andy Harris of Maryland's 1st congressional district, Democrat Johnny Olszewski of the 2nd district, and Democrat Kweisi Mfume of the 7th district.
