Montgomery County is the third-most populous county in the Commonwealth of Pennsylvania, and the 73rd-most populous in the United States. As of the 2020 census, the population of the county was 856,553, representing a 7.1% increase from the 799,884 residents enumerated in the 2010 census. Montgomery County is located adjacent to and northwest of Philadelphia. The county seat and largest city is Norristown. Montgomery County is geographically diverse, ranging from farms and open land in the extreme north of the county to densely populated suburban neighborhoods in the southern and central portions of the county.
Montgomery County is included in the Philadelphia-Camden-Wilmington PA-NJ-DE-MD metropolitan statistical area, sometimes expansively known as the Delaware Valley. The county marks part of the Delaware Valley's northern border with the Lehigh Valley region of Pennsylvania. In 2010, Montgomery County was the 66th-wealthiest county in the country by median household income.
The county was created on September 10, 1784, out of land originally part of Philadelphia County. The first courthouse was housed in the Barley Sheaf Inn. It is believed to have been named either for Richard Montgomery, an American Revolutionary War general killed in 1775 while attempting to capture Quebec City, or for the Welsh county of Montgomeryshire (which was named after one of William the Conqueror's main counselors, Roger de Montgomerie), as it was part of the Welsh Tract, an area of Pennsylvania settled by Quakers from Wales. Early histories of the county indicate the origin of the county's name as uncertain.

Politics
As of November 1, 2021, there are 595,307 registered voters in Montgomery County.
Democratic: 297,227 (49.93%)
Republican: 203,781 (34.23%)
Independent: 60,892 (10.23%)
Third Party: 33,407 (5.61%)
Historically, Montgomery County was a stronghold for the Republican Party. The county was the only one carried by Barbara Hafer in the 1990 gubernatorial election over the incumbent governor, Bob Casey. However, the Democratic Party has made substantial gains in the county over the last quarter-century and gained the registration edge early in 2008.
As in most of Philadelphia's suburbs, the brand of Republicanism practiced in Montgomery County for much of the 20th century was a moderate one. As the national parties have polarized, the county's voters have increasingly supported Democrats at the national level. After voting for the Republican presidential nominee in all but one election from 1952 to 1988, Lyndon Johnson's landslide in 1964, Montgomery County residents have voted for the Democratic presidential nominee for the past seven consecutive elections, with the margins progressively increasing between 1992 and 2008 to 21.8%. The Democratic victory margin decreased in 2012 back to 14.3%, but rebounded in 2016 to 21.3%.
Most county-level offices were held by Republicans until after the 2007 election, when Democrats picked up control of five row offices. Democrats have also won several elections in the Pennsylvania General Assembly in recent years, including two GOP-leaning State House districts in 2004, the 148th with Mike Gerber and the 153rd with Josh Shapiro. Today, although the county is very Democratic at the national level, at the state and local level, it is not specifically partisan.
In the 2004 United States Senate election, Republican Arlen Specter won the county over Montco resident Joe Hoeffel, but Democrat Bob Casey, Jr. out-polled Rick Santorum in the 2006 Senate election. In 2006, Democrat Rick Taylor unseated incumbent Republican Eugene McGill in the 151st (although Taylor lost in 2010 to Republican Todd Stephens) and, in 2008, Democrat Matthew Bradford unseated incumbent Republican Jay Moyer in the 70th. Six of the county's 12 state house seats and four of the county's eight senate seats are now held by Democrats. All four statewide Democratic candidates carried Montgomery in 2008, with Barack Obama receiving 60% of the county's vote. Barack Obama won Montgomery County in 2008 and 2012.
Despite Donald Trump's victory in the state of Pennsylvania in the 2016 election, Montgomery County was one of the few counties in Pennsylvania which swung in the Democratic presidential candidates' direction with Hillary Clinton winning Montgomery County with 58.87% of the vote, an improvement from Barack Obama's 56.6% vote share in 2012. In the 2016 U.S. Senate elections as well as the Pennsylvania Attorney General elections, Montgomery County voted for Katie McGinty and Josh Shapiro, both Democrats. In 2020, Joe Biden received over 60% of the vote in Montgomery County, the first Democrat to do so in the county's history.
Government
Montgomery County is governed by a three-person county commission. The current composition is two Democrats and one Republican. By law, the county commission must have one member of a minority party represented.

Same-sex marriage
On July 24, 2013, Montgomery County Register of Wills D. Bruce Hanes, a Democrat, announced he would begin issuing marriage licenses to same-sex couples, flouting Pennsylvania law banning such unions. Hanes called the commonwealth's ban "arbitrary and suspect", saying he believes it violates the Pennsylvania Constitution and the United States Constitution. The Republican administration of Governor Tom Corbett filed suit in the Commonwealth Court of Pennsylvania in an attempt to block Hanes from licensing same-sex marriage. Commonwealth Court Judge Dan Pellegrini ordered Hanes in September 2013 to stop issuing same-sex marriage licenses. After Federal Judge John Jones threw out Pennsylvania's ban on same-sex marriage in May 2014, calling it unconstitutional, offices in other counties were able to issue these licenses, while Hanes had to wait for the ruling against him to be removed.

Economy
Montgomery County is a suburb of Philadelphia and consequently, many of its residents work in the city. However, Montco is also a major employment center with large business parks in Blue Bell, Lansdale, Fort Washington, Horsham, and King of Prussia which attract thousands of workers from all over the region. The strong job base and taxes generated by those jobs have resulted in Montgomery County receiving the highest credit rating of 'AAA' from Standard & Poor's, one of fewer than 30 counties in the United States with such a rating. In 2012, Moody's downgraded the general obligation rating to Aa1, and in 2018 the rating was revised back to Aaa.
