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",{{cite web|url=https://www.youtube.com/watch?v=OKZDUWpk7jQ| archive-url=https://web.archive.org/web/20190326081827/https://www.youtube.com/watch?v=OKZDUWpk7jQ| archive-date=March 26, 2019 | url-status=dead|title=Get On Board BRT - Vote Now!|last=Rapid Transit - Montgomery County, MD|via=YouTube}}{{cite web|url=https://twitter.com/MoCoCouncilMD/status/798593468499042304|title=@CoUnTy_ExEc talks about his mission to make #MoCo one of the most welcoming places on earth. #CommunityMatterspic.twitter.com/EJuLFi2NAz|first=Montgomery|last=Council|date=November 15, 2016|access-date=November 15, 2016|archive-url=https://web.archive.org/web/20170612095406/https://twitter.com/MoCoCouncilMD/status/798593468499042304|archive-date=June 12, 2017|url-status=live}} in use as early as 2001.{{cite web|date=May 24, 2001|title=Got Plans?|publisher=The Washington Post Company|author=The Going Out Gurus|location=Washington, D.C.|work=With the Entertainment Guide Staff|quote=I'm hoping to answer you and our Silver Spring questioner, who was looking for something this weekend in MoCo.|url=https://www.washingtonpost.com/wp-srv/liveonline/01/gotplans/gotplans0524.htm|access-date=April 15, 2024|archive-date=March 18, 2024|archive-url=https://archive.today/20240318173743/https://www.washingtonpost.com/wp-srv/liveonline/01/gotplans/gotplans0524.htm|url-status=bot: unknown}}

{{Main|History of Montgomery County, Maryland}}

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.

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. Earthquakes are rare; the most recent one, on June 24, 2024, had a 1.8 magnitude and was centered near Spencerville, Maryland."[https://earthquake.usgs.gov/earthquakes/eventpage/us6000n83v/executive M 1.8 - 0 km ENE of Spencerville, Maryland] {{Webarchive|url=https://web.archive.org/web/20240625205800/https://earthquake.usgs.gov/earthquakes/eventpage/us6000n83v/executive|date=June 25, 2024}}".

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".

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 three 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 {{convert|43|in|cm}} of rainfall.{{cite web |title= Intellicast - Rockville Historic Weather Averages in Maryland (20857) |work= Accuweather |access-date= September 4, 2015 |url= http://www.intellicast.com/Local/History.aspx?location=USMD0347 |archive-url= https://web.archive.org/web/20150924035452/http://www.intellicast.com/Local/History.aspx?location=USMD0347 |archive-date= September 24, 2015 |url-status= live |df= mdy-all }} 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 {{cvt|55|F}}. The average summer (June–July–August) afternoon maximum is about {{cvt|85|F}} while the morning minimums average {{cvt|66|F}}. In winter (December–January–February), these averages are {{cvt|44|F}} and {{cvt|28|F}}. Extreme heat waves can raise readings to around and slightly above {{cvt|100|F}}, and arctic blasts can drop lows to {{cvt|-10|F}} to {{cvt|0|F}}. For Rockville, the record high is {{cvt|105|F}} in 1954, while the record low is {{cvt|-13|F}}.

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, and many other areas have since followed suit.

Montgomery County is by far one of the most ethnically and culturally diverse counties in the United States; four of the ten most culturally diverse cities and towns in the U.S. are in Montgomery County: Gaithersburg, ranking second; Germantown, ranking third; Silver Spring, ranking fourth; and Rockville, ranking ninth. Gaithersburg, Germantown, and Silver Spring all rank as more culturally diverse than New York City, San Jose, and Oakland.{{Cite news|last=Hedgpeth|first=Dana|title=Four places in Maryland rank among the nation's most ethnically diverse, study says|language=en-US|newspaper=The Washington Post|url=https://www.washingtonpost.com/news/local/wp/2018/02/13/four-cities-in-maryland-ranked-among-the-most-ethnically-diverse-study-says/|access-date=February 22, 2021|issn=0190-8286|archive-date=October 1, 2020|archive-url=https://web.archive.org/web/20201001145521/https://www.washingtonpost.com/news/local/wp/2018/02/13/four-cities-in-maryland-ranked-among-the-most-ethnically-diverse-study-says/|url-status=live}}{{Cite web|date=February 17, 2021|title=4 Maryland cities in top 10 for most culturally diverse cities in U.S., according to WalletHub|url=https://www.fox5dc.com/news/4-maryland-cities-in-top-10-for-most-culturally-diverse-cities-in-u-s-according-to-wallethub|access-date=February 22, 2021|website=FOX 5 DC|language=en-US|archive-date=February 18, 2021|archive-url=https://web.archive.org/web/20210218081533/https://www.fox5dc.com/news/4-maryland-cities-in-top-10-for-most-culturally-diverse-cities-in-u-s-according-to-wallethub|url-status=live}} Maryland overall is one of six minority-majority states, and the only minority-majority state on the East Coast.{{Cite web|url=https://data.census.gov/cedsci/table?q=B03002&g=0400000US24&tid=ACSDT1Y2019.B03002&hidePreview=true|access-date=February 22, 2021|title=Hispanic or Latino Origin by Race|website=data.census.gov|archive-date=March 4, 2021|archive-url=https://web.archive.org/web/20210304223843/https://data.census.gov/cedsci/table?q=B03002&g=0400000US24&tid=ACSDT1Y2019.B03002&hidePreview=true|url-status=live}}

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.{{Cite web |url=https://montgomeryhistory.org/wp-content/uploads/2018/09/mca_RG01_fa_county_executive.pdf |title=Archived copy |access-date=September 12, 2024 |archive-date=September 26, 2024 |archive-url=https://web.archive.org/web/20240926230408/https://montgomeryhistory.org/wp-content/uploads/2018/09/mca_RG01_fa_county_executive.pdf |url-status=live }}

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.{{cite book |last1=Sween |first1=Jane C. |last2=Offutt |first2=William |title=Montgomery County: Centuries of Change |date=1999 |publisher=American Historical Press |isbn=1-892724-05-7}}{{cite book |last=Boyd |first=T.H.S. |title=The History of Montgomery County, Maryland from Its Earliest Settlement in 1650 to 1879 |url=https://commons.wikimedia.org/wiki/File:The_history_of_Montgomery_county,_Maryland,_from_its_earliest_settlement_in_1650_to_1879_.._(IA_historyofmontgom00boy).pdf |date=1879 |publisher=Regional Publishing Company |location=Clarksburg, MD |access-date=November 28, 2020 |archive-date=February 17, 2022 |archive-url=https://web.archive.org/web/20220217181938/https://commons.wikimedia.org/wiki/File:The_history_of_Montgomery_county,_Maryland,_from_its_earliest_settlement_in_1650_to_1879_.._(IA_historyofmontgom00boy).pdf |url-status=live }}{{rp|52–54}}{{rp|75–83}}

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.{{rp|75–83}}

In 1849, the Seventh Street Turnpike (now called Georgia Avenue) was extended from Washington to Brookeville. The Colesville–Ashton Turnpike was built in 1870 (now parts of Colesville Road, Columbia Pike, and New Hampshire Avenue).{{rp|75–83}}

The United States Army Corps of Engineers built the Washington Aqueduct between 1853 and 1864, to supply water from Great Falls to Washington. The aqueduct was covered in 1875, and it became known as Conduit Road. The Union Arch Bridge, which carries the aqueduct across Cabin John Creek, was the longest single-arch bridge in the world at the time it was completed in 1864. The road is now named MacArthur Boulevard.{{rp|75–83}}

Since 1949 the Montgomery County Agricultural Fair, the largest in the state, showcases farm life in the county. The week long event offers family events, carnival rides, live animals, entertainment and food. Visitors can also view entries of canned and baked goods, clothing, quilts and produce from local county farmers.{{cite web|url=http://www.mcagfair.com/about-us/|title=About Us - The Montgomery County Agricultural Fair|website=www.mcagfair.com|access-date=February 7, 2014|archive-url=https://web.archive.org/web/20140221192131/http://www.mcagfair.com/about-us/|archive-date=February 21, 2014|url-status=live}}

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.{{cite web |url=http://mlis.state.md.us/other/Legislative_Handbooks/Volume%20VI/chapter4.htm |archive-url=https://web.archive.org/web/20080317025037/http://mlis.state.md.us/other/Legislative_Handbooks/Volume%20VI/chapter4.htm |archive-date=March 17, 2008 |title=Special Taxing Districts and Regional Agencies |work=1998 Legislative Handbook |publisher=General Assembly of Maryland |date=1998}} 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:

• Drummond
• Oakmont

Unincorporated areas are also considered as towns by many people and listed in many collections of towns, but they lack local government. Various organizations, such as the United States Census Bureau, the United States Postal Service, and local chambers of commerce, define the communities they wish to recognize differently, and since they are not incorporated, their boundaries have no official status outside the organizations in question. The Census Bureau recognizes the following census-designated places in the county:
