Etymology

The Maryland state legislature named Montgomery County after Richard Montgomery; the county was created from lands that had at one point or another been part of Frederick County. On September 6, 1776, in use as early as 2001.

The county's motto, adopted in 1976, is "Gardez Bien", a French phrase meaning "Watch Well". The county's motto is also the motto of its namesake's family.

History

Prior to 1688, the first tract of land in what is now Montgomery County was granted by Charles I in a charter to the first Lord Baltimore, the head of the Calvert family. The county's creation was a focus of Thomas S. Wootton who, on August 31, 1776, introduced a measure to form a new county from Frederick County, Maryland to aid area residents in simplifying their business affairs. The measure passed, creating the new political entity of Montgomery County in what was then the colonial-era Province of Maryland.

Relief between valley bottoms and hilltops is several hundred feet. Earthquakes are rare; the most recent one, on June 24, 2024, had a 1.8 magnitude and was centered near Spencerville, Maryland.

When Montgomery County was created in 1776, its boundaries were defined as "beginning at the east side of the mouth of Rock Creek on Potomac river [sic], and running with the said river to the mouth of Monocacy, then with a straight line to Par's spring, from thence with the lines of the county to the beginning".

Montgomery County was granted a charter form of government in 1948.

The present County Executive/County Council form of government of Montgomery County dates to November 1968 when the voters changed the form of government from a County Commission/County Manager system, as provided in the original 1948 home rule Charter. The County Commission/County Manager system was seen as inadequate for the growing population of the county who wanted more services assistance and accountability from the government.

The Montgomery County government had a surplus of $654million for the fiscal year ending June 30, 2021.

Law enforcement

County police

The Montgomery County Police Department (MCPD) provides the full spectrum of policing services to the entire county. It was founded in 1922 and is headquartered in Gaithersburg, Maryland. It consists of around 1,300 sworn officers and 650 support personnel, split into 6 districts throughout the county. The department also provides assistance to other nearby departments, such as the Metropolitan Police Department of the District of Columbia and the Prince George's County Police Department, if requested.

County sheriff's office

The Montgomery County Sheriff's Office (MCSO) is a nationally accredited U.S. law enforcement agency and acts as the enforcement arm of the courts in the county. All of its deputy sheriffs are fully certified law enforcement officials with full authority of arrest. The office was created in July 1777 and is the oldest law enforcement agency in Montgomery County. It is headquartered in Rockville, Maryland. It was nationally accredited in 1995, the first county sheriff's office in Maryland to be so. The MCSO has authorized over 165 employees consisting of sworn law enforcement officers and civilian support staff. The office is headed by the sheriff, who has been elected every four years since the 1920s. The current Sheriff is Maxwell C. Uy (D), elected in 2022. Uy is the 62nd Sheriff and the first Asian American to hold that office.

Other agencies

The cities of Rockville, Gaithersburg, Takoma Park, and Chevy Chase Village maintain their own police departments to complement MCPD. State Law Enforcement Agencies to include the Maryland State Police, Maryland Natural Resources Police, and the Maryland Park Police maintain a presence in the county as well.

LGBTIQ+ bill of rights

In October 2020, the Montgomery County Council unanimously passed an ordinance that implemented an LGBTIQ+ bill of rights.

Liquor control

Montgomery County is an alcoholic beverage control county. Beer and wine may also be sold in private stores.

History

In December 1933, when prohibition was repealed in the United States, Montgomery County only allowed dispensaries located in Bethesda, Rockville, and Silver Spring to sell alcoholic beverages. The dispensaries then could sell beer and light wine to retailers in the county for resale. The dispensaries were not allowed to sell hard liquor for on-premises consumption. Country clubs were also allowed to sell beer and light wine for on-premises and off-premises consumption.

The first beer-and-wine license in Montgomery County was issued to Fred Salamy for Fred's Country Store. In 1961, the license was transferred to Henry J. Dietle to be used at Hank Dietle's. Hank Dietle's originally opened in 1916 as a general store named Offutt's.

Until 1964, only three restaurants in the county had liquor licenses to serve liquor by the drink. The county stopped issuing liquor licenses to all other restaurants under a law that had existed since Prohibition.

Following a voter referendum, restaurants and bars could apply for county permits to sell liquor by the drink. John J. McCarthy (D) has served as the State's Attorney since 2007.

Transportation

Roads

thumb|right|I-270 northbound in Rockville

Poor transportation was a hindrance for Montgomery County's farmers who wanted to transport their crops to market in the early 18th century. Montgomery County's first roads, often barely adequate, were built by the 18th century.

One early road, Maryland Route 355, connected Frederick and Georgetown. There was a road, Maryland Route 190 that connected Georgetown and the mouth of the Monocacy River. Plans to continue the road to Cumberland did not come to fruition. Another road connected the Montgomery County Courthouse with Sandy Spring and Baltimore, and one other road connected the courthouse with Bladensburg and Annapolis.

The county's first turnpike was chartered in 1806, but its construction began in 1817. In 1828, the turnpike was completed, running from Georgetown to Rockville. It was the first paved road in Montgomery County. Major routes closer to its rail service area are also covered by WMATA's Metrobus service.

The county also operates a bus rapid transit (BRT) system named Flash.

The Corridor Cities Transitway is a proposed BRT line that would provide an extension of the Red Line corridor from Gaithersburg to Germantown, and eventually to Frederick County.

Rail

thumb|[[Silver Spring station in August 2017, serving the Red Line of the Washington Metro and serving Amtrak and the Brunswick line of MARC]]

Montgomery County is served by three passenger rail systems, with a fourth line under construction.

Amtrak, the U.S. national passenger rail system, operates its Capitol Limited to Rockville, between Washington Union Station and Chicago Union Station.

The Brunswick line of the MARC commuter rail system makes stops at Silver Spring, Kensington, Garrett Park, Rockville, Washington Grove, Gaithersburg, Metropolitan Grove, Germantown, Boyds, Barnesville, and Dickerson, where the line splits into its Frederick and Martinsburg branches.

Both suburban arms of the Red Line of the Washington Metro serve Montgomery County. It follows the CSX right of way to the west, roughly paralleling Route 355 from Friendship Heights to Shady Grove. The eastern side runs between the two tracks of the CSX right of way from Washington Union Station to Silver Spring, and roughly parallels Georgia Avenue, from Silver Spring to Glenmont.

The Purple Line, a light rail system, is currently under construction and is scheduled to open in 2027. The line will run in a generally east-west direction, connecting Montgomery and Prince George's Counties near the Beltway, with 21 stations. The Purple Line will connect directly with four Metro stations, MARC trains and Amtrak.

Air

The Montgomery County Airpark (FAA GAI, ICAO KGAI), a general aviation facility in Gaithersburg, is the major airport in the county. Davis Airport (FAA Identifier W50), a privately owned airstrip, is located in Laytonsville on Hawkins Creamery Road. Commercial air service is provided at the nearby Ronald Reagan Washington National, Washington Dulles International, and BWI Airports.

Education

Education in the county is provided by Montgomery County Public Schools, Montgomery College and other institutions.

Montgomery County Public Schools

Elementary and secondary public schools are operated by the Montgomery County Public Schools (MCPS). The county public school system is the largest school district in Maryland, serving about 162,000 students with 13,000 teachers and 10,000 support staff. The public school system operating budget for Fiscal Year 2019 was $2.6 billion (~$ in ).

MCPS conducted its first 'data deletion week' in 2019, purging its databases of unnecessary student information. Parents said they hoped to shield children from being held accountable in adulthood for youthful mistakes, as well as to guard them from exploitation by what one parent termed "the student data surveillance industrial complex".The district also requires tech companies to annually delete data they collect on schoolchildren. In December 2019 it said GoGuardian had sent formal certification that it had deleted its data, but the district was still waiting for confirmation from Google.

Montgomery College

The county is also served by Montgomery College, a public, open access community college that had a budget of US$315 million for FY2020. The county has no public university of its own, but the state university system does operate a facility called Universities at Shady Grove in Rockville that provides access to baccalaureate and Master's level programs from several of the state's public universities.

Montgomery County Public Libraries

The Montgomery County Public Libraries (MCPL) system includes 23 individual libraries, and had a budget $38 million (~$ in ) for 2015.
