==History==
{{See also|History of Kansas}}

This was part of the large territory of the [[Osage people]], who occupied lands up to present-day [[Saint Louis, Missouri|St. Louis]]. After the [[Indian Removal]], the United States government reserved much of this area as Indian territory for a reservation for the [[Shawnee people]], who were relocated from east of the Mississippi River in the upper Midwest.

The [[Santa Fe Trail]] and [[Oregon Trail|Oregon–California Trail]], which pass through nearby [[Independence, Missouri]], also passed through the county. Johnson County was established in 1855 as one of the first counties in the newly organized [[Kansas Territory]]; it was named for [[Proslavery thought|proslavery]] American [[missionary]] [[Thomas Johnson (Kansas politician)|Thomas Johnson]].<ref>{{cite book | url=https://archive.org/details/bub_gb_9V1IAAAAMAAJ | title=The Origin of Certain Place Names in the United States | publisher=Govt. Print. Off. | author=Gannett, Henry | year=1905 | pages=[https://archive.org/details/bub_gb_9V1IAAAAMAAJ/page/n168 169]}}</ref> The renowned gunfighter [[Wild Bill Hickok]] settled for a time in the county, becoming constable of [[Monticello Township, Johnson County, Kansas|Monticello Township]] in 1858.

Johnson County was the site of many battles between [[Abolitionism in the United States|abolitionists]] and pro-slavery advocates during the period of [[Bleeding Kansas]], prior to the residents voting on whether slavery would be allowed in the territory. In 1862, during the [[American Civil War|Civil War]], Confederate guerrillas from nearby Missouri, led by [[William Quantrill]], raided the Johnson County communities of [[Olathe, Kansas|Olathe]] and [[Spring Hill, Kansas|Spring Hill]]. They killed half a dozen men and destroyed numerous homes and businesses.<ref>{{Cite web|url=https://www.wyohistory.org/encyclopedia/johnson-county-war-1892-invasion-northern-wyoming|title=The Johnson County War: 1892 Invasion of Northern Wyoming {{!}} WyoHistory.org|website=www.wyohistory.org|language=en|access-date=September 14, 2017}}</ref>

The county was largely rural until the early 20th century, when housing subdivisions were developed in the northeastern portion of the county adjacent to [[Kansas City, Missouri]]. Developer [[J. C. Nichols]] spurred the boom in 1914 when he built the [[Mission Hills Country Club (Kansas)|Mission Hills Country Club]] to attract upscale residents who previously had been reluctant to move from Missouri to Kansas.<ref>{{cite book|url=https://books.google.com/books?id=MqMUAAAAYAAJ&q=Mission+Hills+County+Club+Kansas&pg=PA2280 |title=A Standard History of Kansas and Kansans – William E. Connelly – Lewis Publishing Company – 1918 |year=1918 |access-date=April 14, 2012}}</ref> Suburban development continued at a steady pace until the close of [[World War II]].

Following the war, the pace of development exploded, triggered by the return of veterans in need of housing, construction of highways that facilitated commuting from suburbs, and the pent-up demand for new housing. The US Supreme Court ruling in ''[[Brown v. Board of Education]]'' (1954) ruled that segregation of public schools was unconstitutional. Integration of public schools in Kansas City, Missouri, resulted in many white families leaving the inner city, resulting in increased migration to the county for new housing and what were considered higher quality public schools, generally an indicator of higher economic status. From the mid-1980s, the pace of growth increased significantly, with the county adding 100,000 residents each decade between the 1990 census and 2010 census.

The 1952 Johnson County Courthouse was closed in 2020, then demolished in 2021.<ref name="OldCourtHouse">{{cite web |title=Demolition of old Johnson County Courthouse completed |url=https://www.jocogov.org/article/2021/08/26/16711 |website=Johnson County Government |archive-url=https://web.archive.org/web/20210829214257/https://www.jocogov.org/article/2021/08/26/16711 |archive-date=August 29, 2021 |date=August 26, 2021 |url-status=live}}</ref> It was replaced by a seven-story courthouse in 2021 after over two years of construction.

==Geography==
[[File:Olathe kansas city hall 2009.jpg|thumb|right|[[Olathe, Kansas|Olathe]] City Hall (2009)]]
According to the [[United States Census Bureau]], the county has a total area of {{convert|480|sqmi}}, of which {{convert|473|sqmi}} is land and {{convert|6.5|sqmi}} (1.4%) is water.<ref>{{cite web|url=https://www.census.gov/geographies/reference-files/time-series/geo/gazetteer-files.html|publisher=[[United States Census Bureau]]|access-date=April 23, 2011|date=February 12, 2011|title=US Gazetteer files: 2010, 2000, and 1990}}</ref>

===Topography===
The natural [[topography]] of the county consists of gently rolling terrain. The [[Kansas River]] forms a portion of the northwestern boundary of the county. The elevation generally increases from north to south as the distance from the Kansas and [[Missouri River|Missouri]] rivers increases.

===Watersheds and streams===
The county is drained by the watersheds of the [[Kansas River|Kansas]], [[Blue River (Missouri)|Blue]], and [[Marais des Cygnes River|Marais des Cygnes]], all of which are part of the [[Missouri River]] watershed. Located in northeastern Kansas, the county receives plentiful rainfall. The county contains numerous small streams, including Kill Creek, Mill Creek, Turkey Creek, Indian Creek, Brush Creek, Tomahawk Creek, the Blue River, Bull Creek and Little Bull Creek.

Kill Creek begins in the southwestern portion of the county and flows northward into the Kansas River at [[DeSoto, Kansas|De Soto]]. Mill Creek begins in the central portion of the county in Olathe, flowing northward it empties into the Kansas River at [[Shawnee, Kansas|Shawnee]]. Turkey Creek and Brush Creek each begin in northeastern Johnson County. Turkey Creek flows northeastward into [[Wyandotte County, Kansas|Wyandotte County]] and joins the [[Kansas River]] just before its confluence with the Missouri River at [[Kaw Point]]. Brush Creek flows east-northeastward through [[Prairie Village, Kansas|Prairie Village]] and [[Mission Hills, Kansas|Mission Hills]], entering Kansas City, Missouri, within the median of [[Ward Parkway]] and passing the [[Country Club Plaza]] before emptying into the Blue River east of the Country Club Plaza and north of [[Swope Park]]. Indian Creek begins in the southern portion of Olathe and Tomahawk Creek begins in southern Overland Park. Each flows northeastward meeting in [[Leawood, Kansas|Leawood]], where the stream retains the name of Indian Creek, just before crossing the state line and entering the [[Blue River (Missouri River tributary)|Blue River]] in Kansas City, Missouri. The Blue River begins in rural southern Johnson County and flows north-northeastward through the southeastern portion of the county and crossing the state line just east of the intersection of 151st Street and Kenneth Road in southern [[Overland Park]]. The Blue River flows through southern and eastern Kansas City before joining the Missouri River. Bull Creek and Little Bull Creek begin in rural southwestern Johnson County and flow southward where they enter [[Hillsdale Lake]] before continuing into [[Franklin County, Kansas|Franklin County]], eventually joining the Marais des Cygnes at [[Paola, Kansas|Paola]].

===Flora and fauna===
The county consists primarily of prairie grassland, with corridors of forested areas along streams and rivers.

Johnson County is entirely located within [[Kansas's 3rd congressional district]], which has been represented by Democrat [[Sharice Davids]] since 2019. The two U.S. Senators from Kansas are Republicans [[Roger Marshall]] and [[Jerry Moran]].

Johnson County was historically a Republican stronghold. It was won by the GOP in every presidential election from [[1920 United States presidential election in Kansas|1920]] to [[2016 United States presidential election in Kansas|2016]], including Barry Goldwater’s [[1964 United States presidential election in Kansas|1964 election]] victory despite his statewide loss. The county was one of the few to reject [[Franklin Roosevelt]] in all four of his successful campaigns, with his closest margin coming in 1932, where he lost by just two votes.<!-- <ref>{{cite web|url=http://uselectionatlas.org/ |title=Presidential Election Results by County 1960–Present |publisher=Uselectionatlas.org |date=January 24, 1999 |access-date=April 14, 2012}}</ref> --><ref>{{cite web|url=http://geoelections.free.fr/USA/accueil.htm |title=Presidential Election Results by County Pre 1960 |publisher=Geoelections.free.fr |access-date=April 14, 2012}}</ref> However, the margin narrowed considerably in the early 2000s. In 2008, [[Barack Obama]] became the first Democrat since [[Lyndon Johnson]] to win as much as 40 percent of the county's vote. In [[2016 United States presidential election in Kansas|2016]], Republican [[Donald Trump]] won the county by less than three points, as the GOP’s shift toward [[right-wing populism]] alienated moderate voters. In [[2020 United States presidential election in Kansas|2020]], [[Joe Biden]] became the first Democrat to win the county since [[Woodrow Wilson]] in 1916, securing an 8% margin and the highest share of the vote ever for a Democrat there. In [[2024 United States presidential election in Kansas|2024]], [[Kamala Harris]] not only carried the county but achieved the highest Democratic vote share in its history, becoming the first Democrat to lose a presidential election while carrying Johnson County since [[1896 United States presidential election in Kansas|1896]].

This leftward shift was mirrored in the state’s Senate races, where Democrats won Johnson County in [[2020 United States Senate election in Kansas|2020]] and [[2022 United States Senate election in Kansas|2022]], despite losing statewide. Once a classic suburban Republican bastion, the county now leans Democratic at the national level, reflecting broader trends in Kansas’s suburban areas.

On November 8, 2020, Democrats made historic gains in Johnson County, securing a majority on the Board of Commissioners for the first time in the county’s history. In both the 2022 and 2024 elections, Democrats expanded their majority on the Board and flipped the Sheriff’s office for the first time in 96 years.<ref>{{cite news |last=Kraske |first=Steve |date=13 November 2024|title=Byron Roberson will be the first Black sheriff in Johnson County history |url=https://www.kcur.org/podcast/up-to-date/2024-11-13/byron-roberson-will-be-the-first-black-sheriff-in-johnson-county-history |work=KCUR 89.3 |location= |access-date=}}</ref><ref>{{Cite web |url=https://www.jocoelection.org/sites/default/files/2022-05/november_3_2020_general_election_-_official_final_results.pdf? |title=Official Final Results |date=12 November 2020 |website=jocoelection.org |access-date= 27 December 2024}}</ref>

===State representation===
Johnson County is home to 25 [[Kansas House of Representatives|Kansas state representatives]] and nine [[Kansas Senate|Kansas state senators]]. Thirteen out of 25 of Johnson County's representatives are Republicans, as are six of the county's nine senators.<ref>{{Cite web|url=https://www.jocoelection.org/Directory/D-Representatives.htm|title=Johnson County Election Office {{!}} State Representatives|website=www.jocoelection.org|language=en|access-date=October 28, 2017|archive-date=October 29, 2017|archive-url=https://web.archive.org/web/20171029065636/https://www.jocoelection.org/Directory/D-Representatives.htm|url-status=dead}}</ref><ref>{{Cite web|url=https://www.jocoelection.org/Directory/D-Senators.htm|title=Johnson County Election Office {{!}} State Senators|website=www.jocoelection.org|language=en|access-date=October 28, 2017|archive-date=October 29, 2017|archive-url=https://web.archive.org/web/20171029065515/https://www.jocoelection.org/Directory/D-Senators.htm|url-status=dead}}</ref> Numerous Republicans from the area identify as [[Rockefeller Republicans|moderates]], compared to some of the more ideological hard-liners from other parts of the state.

===County government and unincorporated areas===
The county government is administered by an elected, seven-member Board of County Commissioners, with six elected from [[single-member districts]] and one [[at-large]].<ref name="bocc.jocogov.org">{{cite web |title=Board of County Commissioners |url=http://jocogov.org/dept/board-county-commissioners |access-date=March 10, 2023 |publisher=www.jocogov.org}}</ref>  Governance of the county is divided into six districts. The county government has full jurisdiction of the unincorporated areas of the county and limited jurisdiction of those areas of the county within incorporated places. For instance, decisions regarding the regulation of land use, development and zoning in unincorporated areas of the county are the responsibility of the county government, whereas such decisions for areas within incorporated places are the jurisdiction of the incorporated city of which the property is a part.

===Sales taxes===
The current sales tax rate in Johnson County is 7.975%, higher than the 6.5% rate in [[Wyandotte County, Kansas|Wyandotte]] (where [[Kansas City, Kansas|Kansas City]], [[Kansas]] is located).<ref name="KCTA">Kansas County Treasurer's Association [http://www.kansastreasurers.org/kscotax.htm Kansas Sales Tax Rates by County] {{webarchive|url=https://web.archive.org/web/20110807094446/http://www.kansastreasurers.org/kscotax.htm |date=August 7, 2011}}</ref> The sales tax rates of each of the surrounding counties are nearly the same as the rate in Johnson County.<ref name="KCTA" /> Individual cities have additional sales taxes.

===Property taxes===
Property taxes are a conglomeration of state, county, city, and school district taxes. Property tax rates are generally lower in Johnson County because property values in the county are higher than in other counties throughout Kansas.

In April 2024, Johnson County Sheriff Calvin Hayden claimed that he "had a search warrant in hand" when local election officials "decided in a hurry to destroy" ballots from 2019, 2020 and 2021, despite Kansas state law ordering the regular destruction of old ballots, and the local officials having informed Hayden in November 2023 that they would move to destroy the old ballots, which Hayden had asked to be preserved during his investigation of an election software firm. The local prosecutors' office said that it was "unaware of any search warrant being submitted to a judge for review". In May 2024, when Hayden was questioned on which judge approved his search warrant, Hayden responded: "there's no judge"; when the questioner replied: "A judge has to sign a search warrant to be valid", Hayden responded: "I didn’t say it was valid".<ref>{{cite news |last1=Ritter |first1=Sarah |title=JoCo Sheriff Hayden lied about having warrant to seize old ballots for election probe |url=https://www.kansascity.com/news/local/article287798700.html |access-date=May 9, 2024 |work=The Kansas City Star |date=April 18, 2024}}</ref><ref>{{cite news |last1=Shorman |first1=Jonathan |last2=Ritter |first2=Sarah |title='I didn't say it was valid': Johnson County sheriff admits he didn't have signed warrant |url=https://www.kansascity.com/news/politics-government/article288380810.html |access-date=May 9, 2024 |work=The Kansas City Star |date=May 8, 2024}}</ref>

==Transportation==
Johnson County has a grid network through most of the county, with a road every mile. The grid has facilitated rapid growth and easy access. [[Interstate 435]] runs through much of the county, and serves as a developmental "border" in the northbound–southbound portion. The westbound–eastbound part of I-435 divides the county into a northern and southern section. The northern section is older, while the southern portion is the fastest-growing area in Johnson County, containing a massive volume of new homes.{{citation needed|date=March 2011}}

The Johnson County numbered street grid generally begins at 47th Street, the Wyandotte County line (the lowest numbered street is 40th Street in Bonner Springs), and is a continuation of the adjacent [[Kansas City, Missouri]], street grid. The grid continues to 215th Street, and into Miami County (with somewhat differently named roads) to 407th Street at the Miami-Linn county line, with most suburban development ending around 167th Street. Named streets in the grid run from State Line Road (1900 West) to County Line Road (40699 West) at the Douglas County line. A portion of the grid extends north from Westwood into the Rosedale area in Kansas City, Kansas.

Another principal highway running through the area is [[Interstate 35 in Kansas|Interstate 35]], which runs diagonally through the county, entering it near [[Downtown Kansas City]], and continuing through Olathe and Gardner. Outside the county, it eventually leads to [[Duluth, Minnesota]] in the north and the US–Mexico border in the south. [[U.S. Route 69 in Kansas|U.S. 69]] also serves Johnson County, entering from Wyandotte County at the south end of [[Interstate 635 (Kansas–Missouri)|Interstate 635]]. Much of U.S. 69 within the county is freeway; this freeway eventually heads south and connects to [[Fort Scott, Kansas|Fort Scott]] and the rest of southeastern Kansas.

===Townships===
Johnson County was originally divided into nine [[Civil township|townships]], two of which have since been eliminated by the annexation of all their territory into independent municipalities.
