Montgomery County , officially the County of Montgomery ,  is a county in the U.S. state of Maryland . As of the 2010 census , the population was 971,777, with a 2014 estimate putting the population at 1,030,447.  It is the most populous county in Maryland. The county seat and largest municipality is Rockville , although the census-designated place of Germantown is the most populous place. 
Montgomery County is included in the Washington–Arlington–Alexandria, DC–VA–MD–WV Metropolitan Statistical Area . Most of the county's residents live in unincorporated locales, of which the most built up are Silver Spring , and Bethesda , though the incorporated cities of Rockville and Gaithersburg are also large population centers as are many smaller but significant places.
As one of the most affluent counties in the United States,  it also has the highest percentage (29.2%) of residents over 25 years of age who hold post-graduate degrees.  In 2011, it was ranked by Forbes as the 10th richest in the United States , with a median household income of $92,213. 
Montgomery County, like other inner Washington, D.C. suburban counties, contains many major U.S. government offices, scientific research and learning centers, and business campuses, which provide a significant amount of revenue for the county. 
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,  Thomas Sprigg Wootton from Rockville, Maryland, introduced legislation, while serving at the Maryland Constitutional Convention, to create lower Frederick County as Montgomery County. The name, Montgomery County, along with the founding of Washington County, Maryland, after George Washington, was the first time in American history that counties and provinces in the thirteen colonies were not named after British referents. The name use of Montgomery and Washington County were seen as further defiance to Great Britain during the American Revolutionary War . The county's nickname of "MoCo" is derived from "Montgomery County", after the pattern of SoHo, Manhattan .
Before European immigration, the land now known as Montgomery County was covered in a vast swath of forest crossed by the creeks and small streams that feed the Potomac and Patuxent rivers. A few small villages of the Piscataway , members of the Algonquian people, were scattered across the southern portions of the county. North of the Great Falls of the Potomac, there were few permanent settlements, and the Piscataway shared hunting camps and foot paths with members of rival peoples like the Susquehannocks and the Senecas .
These lands were claimed by Europeans for the first time when George Calvert, 1st Baron Baltimore was granted the charter for the colony of Maryland by Charles I of England . However, it was not until 1688 that the first tract of land in what is now Montgomery County was granted by the Calvert family to an individual colonist, a wealthy and prominent early Marylander named Henry Darnall . He and other early claimants had no intention of settling their families. They were little more than speculators, securing grants from the colonial leadership and then selling their lands in pieces to settlers. Thus, it was not until approximately 1715 that the first British settlers began building farms and plantations in the area.
These earliest settlers were English or Scottish immigrants from other portions of Maryland, German settlers moving down from Pennsylvania, or Quakers who came to settle on land granted to a convert named James Brooke in what is now Brookeville . Most of these early settlers were small farmers, growing wheat and a variety of other subsistence crops in addition to the region's main cash crop, tobacco. Many of the farmers owned slaves. They transported the tobacco they grew to market through the Potomac River port of Georgetown . Sparsely settled, the area's farms and taverns were nonetheless of strategic importance as access to the interior. General Edward Braddock 's army traveled through the county on the way to its disastrous defeat at Fort Duquesne during the French and Indian War .
Like other regions of the American colonies, the region that is now Montgomery County saw protests against British taxation in the years before the American Revolution . In 1774, local residents met at Hungerford's Tavern and agreed to break off commerce with Great Britain. Following the signing of the Declaration of Independence , representatives of the area helped to draft the new state constitution and began to build a Maryland free of proprietary control. On September 6, 1776, the Maryland Constitutional Convention formed Montgomery County from lands that had at one point or another been part of Charles , Prince George's and Frederick Counties, naming it after General Richard Montgomery . The leaders of the new county chose as their county seat an area adjacent to Hungerford's Tavern near the center of the county, which later became Rockville . The newly formed Montgomery County supplied arms, food and forage for the Continental Army during the Revolution, in addition to soldiers.
In 1791, portions of Montgomery County, including Georgetown , were ceded to form the new District of Columbia , along with portions of Prince George's County, Maryland , as well as parts of Virginia that were later returned to Virginia .
In 1828, construction on the C&O Canal commenced and was completed in 1850. Laborers were. primarily Irish immigrants Throughout the 19th century, agriculture dominated the economy in Montgomery County, with slaves playing a significant role, though the vast majority of farmers owned 10 slaves or less rather than large plantations. In the first half of the 19th century, low tobacco prices and worn-out soil caused many tobacco farms to be abandoned. Crop production gradually shifted away from tobacco and toward wheat and corn . Prior to the Civil War, Montgomery County allied itself with other slaveholding counties in southern Maryland and the Eastern Shore. Montgomery County was important in the abolitionist movement, especially among the Quakers in the northern part of the county near Sandy Spring . Josiah Henson grew up as a slave on the Riley farm south of Rockville. He wrote about his experiences in a memoir which became the basis for Harriet Beecher Stowe 's Uncle Tom's Cabin (1852). A slave cabin where he is believed to have spent time still stands at the end of a driveway off Old Georgetown Road.
Until 1860, only private schools existed in Montgomery County. Initially, schools for European American students were built. A school in Rockville for free African-Americans existed until 1866.  Another school for African-Americans was opened by 1877 in Rockville. 
Montgomery County's proximity to the nation's capital and split sympathies to North and South resulted in it being occupied by Union forces during the Civil War . The county was "invaded" on multiple occasions by Confederate and Union forces. 
In 1855, work on the Metropolitan Branch of the Baltimore & Ohio Railroad began, in order to provide a route between Washington, D.C., and Point of Rocks, Maryland .  In 1873, the railroad opened. The railroad spurred development at Takoma Park , Kensington , Garrett Park and Chevy Chase . By providing a much-needed transportation link, it also greatly increased the value of farmland and spurred the development of a dairy industry in the county.
During the Jim Crow era, masked mobs of local white men carried out two separate lynchings of African-American men in Montgomery County on Rockville's courthouse lawn. John Diggs was violently lynched in 1880 and Sydney Randolph similarly murdered in 1896.   Neither man was found guilty in a court of law. Nor was anyone punished for the lynchings. On that same lawn, the Maryland Historical Society maintains a monument to the Confederate army as "heroes of the thin grey line",   because Montgomery County, like the rest of Maryland, was divided over the issue of secession.  One vocal sociologist has claimed Montgomery County was not welcoming of the Confederates during the Civil War.   No memorial exists for victims of Montgomery County's lynchings.
20th and 21st centuries
On July 1, 1922, the Montgomery County Police Department was established.  Prior to that time, law enforcement duties rested in the Montgomery County Sheriff and designated constables.  In 1922, the police department consisted of three to six officers who were appointed to two-year terms by the Board of County Commissioners, one of whom would be appointed as Chief.  In 1927, the police department was enlarged to twenty officers. 
The county began with most legislative power in the hands of the Maryland state government, with a five-person Montgomery County Board of Commissioners who oversaw the administration of the county but could neither pass county laws nor enact policies. 
In 1915, Maryland amended its constitution.  According to the constitutional amendment,  a county's residents may propose a petition to create a nonpartisan Charter Board.  If the petition receives signatures from at least twenty percent of the county's registered voters, all county residents would vote to select the members of the Charter Board during the next general election.  The Charter Board would be authorized to draft a new system of county government, which could include a county council with the power to enact legislation and policies.  Charter Board's proposal would then be voted upon by registered voters during the following general election, and it would be enacted if approved by the voters. 
The county commissioners authorized the Brookings Institution to study the existing county government structure and suggest recommendations in 1938.  The 720-page report opined that the county had outgrown its form of government.  The study recommended the creation of a nonpartisan county council consisting of nine members representing defined districts of the county who could pass legislation, determine policy, and control over the administration of the county.  The study also recommended the hiring of a county administrator, the creation of an independent comptroller in charge of county finances, and a civil service commission.  The Montgomery County Civic Federation praised the study for its comprehensiveness.  The county commissioners appointed a citizen's committee to determine how to enact the study's recommendations.  The county commissioners strongly criticized the recommendation to create a county council, both because the council would be nonpartisan and because each county resident would be able to vote for only one representative rather than for all nine. 
In 1942, Montgomery County Charter Committee was organized, which was formed primarily to circulate petitions to form a Charter Board.  The Charter Board petitioned to form a county council with the power to pass laws without the consent of the Maryland General Assembly and with authority over the administration the county.  While the Democratic Party did not explicitly denounce the charter,  it issued a statement calling out the ostensibly nonpartisan movement for hidden partisan goals  and claimed that backers of the charter petition for their alleged personal and political attacks on the Democratic Party and its officials.  The newly formed Independent Party endorsed the charter, praising county residents' goal of improving their form of government.  In the November 1942 election, county residents voted in favor of forming a Charter Board. 
In 1943, the Charter Board released its draft charter.  The council would have nine unpaid members,  of which five would represent each of five single-member districts and four would represent the county at-large.  Council seats would be nonpartisan, each seat would be held for four years, and elections would occur every two years.  The council would have the power to enact legislation and hire a county manager, to whom all governmental department heads would report.  All sessions of the council would be open to the public.  The office of county treasurer would be abolished and replaced by a director of finance, who would be responsible for assessment and collection of taxes, assessments, and licenses, custody and disbursement of public funds and property, and preparation of monthly financial statements.  A department of public works, department of education, department of safety, department of welfare, and department of health would also be created. 
The Montgomery County Charter Board opened its campaign headquarters in Bethesda, to serve as an information center regarding the draft charter.  The Charter Board emphasized that the draft charter would allow for county affairs to be decided by local representatives rather than by a vote of members of the Maryland General Assembly who represent citizens of all parts of the state.  Another group opposing the draft charter opened its headquarters in Bethesda.  The group said there was no good reason to abolish the functional state-level system already in place, and that the draft charter would increase taxes and establish heads of governmental agencies with indefinite terms who are not directly accountable to the public.  The group also said that making the council seats nonpartisan would go against the country's political history.  The editorial board of The Washington Post supported the draft charter.  The Montgomery County League of Women Voters also endorsed the draft charter. 
In a near-record turnout,  a 1946 vote to enact a home-rule charter failed by a vote of 14,471 to 13,270.  Following the vote, proponents of the charter said they would not give up the fight. 
Several months later, Montgomery County Democratic Party leader Col. E. Brooke Lee said he would support Montgomery County home rule by way of an act of the Maryland state legislature.  Lee proposed a bill to create a position of county supervisor, who would be in charge of routine county business, would appoint county employees subject to civil service rules and regulations, would supervise expenditures, and would prepare the operating and capital budgets.  The bill did not disband the county commissioners or create a county council.  The bill passed the state legislature and was signed by Governor Herbert R. O'Conor in 1945.  The county commissioners appointed Willard F. Day to the position. 
In 1948, by a vote of 17,809 in favor and 13,752 against, voters approved a charter for a "Council-Manager" form of government, making Montgomery County the first home-rule county in Maryland.  The charter created an elected seven-member County Council with the power to pass local laws.  All seven Council Members would be elected at-large by all county residents.  Five would have to live in five different residence districts, while the other two could live anywhere within the county.  The Council would serve as both the legislative and executive functions of the county.  Council members would elect one of their own to serve as president of the Council.  The charter also authorized the hiring of a county manager, the top administrative official,  who could be dismissed by the Council after a public hearing.  The charter created a department of public works, department of finance, and office of the county attorney, while it abolished the positions of county treasurer and police commissioner.  The first County Council was elected in 1949. 
In 1962, a county civic group advocated for the election of a county executive.  The group's report said that the new position would give citizens another place to go if their concerns were refused by the Montgomery County Council.  The group said that the fact that the county had four appointed county managers in thirteen years demonstrates that establishing the position in 1948 had not been a stunning success.  The group also advocated for nonpartisan elections for council members.  Among the reasons for the suggested changes in governance is the fact that the county's population had more than doubled since the governmental system had been established in 1948. 
In 1966, the Montgomery County Council adopted a proposed charter amendment to create a new elected position of County Executive.  Elected to a four-year term, the County Executive could veto legislation passed by the County Council, although five members of the County Council could vote to overrule the veto.  All Council Members would continue to be at-large, but they would need to live in seven different residence districts.  Republicans favored a referendum on the proposed charter amendment, while Democrats favored it in principle but urged the specific amendment's defeat because the duties of the County Executive were not specific enough.   In the referendum held in September 1966,  the referendum was defeated, with 57 percent of voters opposed. 
In February 1967, the Montgomery County Council formed a commission to draft a charter amendment to elect a county executive.  The commission's plan was to separate the legislative and executive functions of government.  The county council would continue to be the legislative branch of county government, and an elected full-time County Executive who could veto legislation passed by the Council; it would take five votes by the Council to override a veto.  The County Executive would hire a chief administrative officer to supervise the daily operations of the government.  All Council Members would be elected at-large by all county residents, but five of the seven would need to live in each of five different residential districts of substantially equal population.  In November 1968, the charter amendment was approved, with 53 percent of votes in favor. 
In November 1986, voters amended the Charter to increase the number of Council seats in the 1990 election from seven to nine. Now five members are elected by the voters of their council district and four are elected at-large. Each voter may vote for five council members; four at-large and one from the district in which they reside. 
In November 1995, the City of Takoma Park held a state-sponsored referendum asking whether the portions of the city in Prince George's County should be annexed to Montgomery County or vice versa. The majority of votes in the referendum were in favor of unification of the entire city in Montgomery County.  Following subsequent approval by both counties' councils and the Maryland General Assembly , the county line was moved to include the entire city into Montgomery County (including territory in Prince George's County newly annexed by the city) on July 1, 1997.  This added about 800 residents to Montgomery County's population. 
According to the U.S. Census Bureau , the county has a total area of 507 square miles (1,310 km 2 ), of which 491 square miles (1,270 km 2 ) is land and 16 square miles (41 km 2 ) (3.1%) is water.  Montgomery County lies entirely inside the Piedmont plateau . The topography is generally rolling. Elevations range from a low of near sea level along the Potomac River to about 875 feet in the northernmost portion of the county north of Damascus. Relief between valley bottoms and hilltops is several hundred feet.
When Montgomery County was created in 1776, its boundaries were defined as "beginning at the east side of the mouth of Rock Creek on Potowmac 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".
The county's boundary forms a sliver of land at the far northern tip of the county that is several miles long and averages less than 200 yards wide. In fact, a single house on Lakeview Drive and its yard is sectioned by this sliver into 3 portions, each separately contained within Montgomery, Frederick and Howard Counties. These jurisdictions and Carroll County meet at a single point at Parr's Spring on Parr's Ridge .

Montgomery County lies within the northern portions of the humid subtropical climate . It has four distinct seasons, including hot, humid summers and cool winters.
Precipitation is fairly evenly distributed throughout the year, with an average of 43 inches (110 cm) of rainfall.  Thunderstorms are common during the summer months, and account for the majority of the average 35 days with thunder per year. Heavy precipitation is most common in summer thunderstorms, but drought periods are more likely during these months because summer precipitation is more variable than winter.
The mean annual temperature is 55 °F (13 °C). The average summer (June–July–August) afternoon maximum is about 85 °F (29 °C) while the morning minimums average 66 °F (19 °C). In winter (December–January–February), these averages are 44 °F (7 °C) and 28 °F (−2 °C). Extreme heat waves can raise readings to around and slightly above 100 °F (38 °C), and arctic blasts can drop lows to −10 °F (−23 °C) to 0 °F (−18 °C). For Rockville , the record high is 105 °F (41 °C) in 1954, while the record low is −13 °F (−25 °C). 
Lower elevations in the south, such as Silver Spring , receive an average of 17.5 inches (44 cm) of snowfall per year.  Higher elevations in the north, such as Damascus ,  receive an average of 21.3 inches (54 cm) of snowfall per year.  During a particularly snowy winter, Damascus received 79 inches (200 cm) during the 2009–2010 season. 
Since the 1970s, the county has had in place a Moderately Priced Dwelling Unit (MPDU) zoning plan that requires developers to include affordable housing in any new residential developments that they construct in the county. The goal is to create socioeconomically mixed neighborhoods and schools so the rich and poor are not isolated in separate parts of the county. Developers who provide for more than the minimum amount of MPDUs are rewarded with permission to increase the density of their developments, which allows them to build more housing and generate more revenue . Montgomery County was one of the first counties in the U.S. to adopt such a plan, but many other areas have since followed suit.

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 Montgomery County Police Department provides county-wide law enforcement services, although several cities including Rockville and Gaithersburg maintain their own police departments to complement MCPD. Maryland State Police patrol Interstate highways 495 (the "Beltway") and 270 and assist county and city police in investigation of some major crimes.
The office of the county executive was established in 1970. The first executive was James P. Gleason. The current executive is Isiah "Ike" Leggett, who was sworn in for his first term on December 4, 2006. He was reelected on November 2, 2010 and on November 4, 2014.
The last Republican serving on the Montgomery County Council, Howard A. Denis of District 1 (Potomac/Bethesda), was defeated in 2006. The board has since been all-Democratic. The members of the County Council for the 2014–2018 term are:

Montgomery County has a budget of $2.3 billion. Approximately $128 million are invested in Montgomery County Public Schools.
Montgomery and Prince George's Counties share a bi-county planning and parks agency in the Maryland-National Capital Park and Planning Commission (often referred to as Park and Planning or its initials M-NCPPC by county residents) and a public bi-county water and sewer utility in the Washington Suburban Sanitary Commission (WSSC).
Montgomery County is an alcoholic beverage control county. Beer and wine may still be sold in individual stores and at a single location within the county for a store chain.
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.  The dry towns of Kensington , Poolesville , and Takoma Park were allowed to keep their own bans in place.

The "Smondrowski Amendment"
On November 11, 2014, the Board approved an amendment introduced by Rebecca Smondrowksi to modify the school calendar to delete all references to religious holidays such as Christmas, Easter, Yom Kippur and Rosh Hashanah.

Special Tax Districts
Occupying a middle ground between incorporated and unincorporated areas are Special Tax Districts, quasi-municipal unincorporated areas created by legislation passed by either the Maryland General Assembly or the county.  The Special Tax Districts generally have limited purposes, such as providing some municipal services or improvements to drainage or street lighting.  Special Tax Districts lack home rule authority and must petition their cognizant governmental entity for changes affecting the authority of the district. The four incorporated villages of Montgomery County and the town of Chevy Chase View were originally established as Special Tax Districts. Four Special Tax Districts remain in the county:
