Jackson County was long home to members of the indigenousOsage tribe, who occupied this territory at the time of European encounter. The first known European explorers wereFrenchtrappers who used theMissouri River as a highway for explorations and trading with regionalNative American tribes. Jackson County was claimed as a part of the territory ofNew France, until 1763 and theBritish victory in theFrench and Indian War. After that, France ceded this territory west of the Mississippi River to Great Britain's ally,Spain. In 1800 Spain was forced by France in theThird Treaty of San Ildefonso to return itsLouisiana Territory (of which modern Jackson County formed a part) to France. Soon abandoning its claims in North America, Napoleon of France sold the territory to the United States in theLouisiana Purchase of 1803.
Operating on behalf of PresidentThomas Jefferson, explorersMeriwether Lewis andWilliam Clark passed through Jackson County on their notableLewis and Clark Expedition in 1804, to survey peoples, property and resources of theLouisiana Territory. Among other items, their report indicated a "high, commanding position" along the river within the current boundaries of Jackson County; in 1808Fort Osage was constructed there. This stockade and trading post was one of the first U.S. military installations within the Louisiana Purchase territory, and remained active until 1822.
In 1821, Jackson County was included in the newly admitted state ofMissouri. Jackson County was organized on December 15, 1826, and named forAndrew Jackson,U.S. Senator from Tennessee and military hero of theWar of 1812, who would ascend to thePresidency shortly after, in 1829.[5][6] Its county seat was designated as Independence, then a minuscule settlement near a spring. However, the rapid increase in westward exploration and expansion ultimately resulted in Independence becoming the starting point for three of the great Westward Trails: theSanta Fe Trail, theOregon Trail, and theCalifornia Trail. Following theAmerican Civil War and construction of railroads through this area, nearby Kansas City, Missouri, ultimately eclipsed Independence, though both towns remain county seats.
In 1838, the "Town Company" bought a small piece of land along the Missouri River in northern Jackson County, establishing "Westport Landing" (today this is known as theRiver Market district). The area outside Westport Landing was renamed in 1839 as the "Town of Kansas", after the localKanza or Kaw tribe.
The town was chartered by Jackson County in 1850 and incorporated by the State of Missouri in 1853 as the "City of Kansas". In 1889, with a population of around 60,000, the city adopted a new charter and changed its name to Kansas City. In 1897, Kansas City annexed Westport.
Jackson County figures prominently in the history of the Church of Jesus Christ of Latter Day Saints, also known as Mormons. The Church was formed in Palmyra,New York, in 1830, located in Western New York, north of the Finger Lakes Region. March 1831 PresidentJoseph Smith said that a location on the Missouri–Kansas border was to be thelatter-day "New Jerusalem"[7] with the "center place" located in Independence, thecounty seat.[8] Traveling to the area in the summer of 1831, Smith and some associates formally proclaimed Jackson County as the site in a ceremony in August 1831.[9]
Leadership and members of the Church began moving to Jackson County soon after but open conflict with earlier settlers ensued, driven by religious and cultural differences. Many early settlers along the Missouri River had come from the upper South: Kentucky and Tennessee, for instance, and brought their slaves andpro-slavery customs with them. They believed that the "Yankee" Mormons, from New York and northern states, wereabolitionists.[10] Mobs in the public and private sector used force to drive individual Saints from Jackson to nearby counties within Missouri and put Latter Day Saints on notice that they had until November 6, 1833, to leave the countyen masse. On November 23, 1833, the few remaining LDS residents wereordered to leave Jackson County. By mid-1839, following theMissouri Mormon War, the Mormons were driven from the state altogether. They did not return to Jackson County or Missouri in significant numbers until 1867, two years after the end of the Civil War.
During theCivil War, Jackson County was the scene of several engagements, the most notable of which was theBattle of Westport in 1864, sometimes referred to as "theGettysburg of Missouri". The Union victory here firmly established Northern control of Missouri, and led to the failure of Confederate GeneralSterling Price'sMissouri expedition. Other noteworthy battles were fought inIndependence in 1862,Lone Jack a few days later, and again inIndependence in 1864.
Jackson County was strongly affected by Union GeneralThomas Ewing's infamousGeneral Order No. 11 (1863). With large numbers of Confederate sympathizers living within its boundaries, and active Confederate operations in the area a frequent occurrence, the Union command was determined to deprive Confederatebushwhackers of all local support. Ewing's decree practically emptied the rural portions of the county, and resulted in the burning of large portions of Jackson and adjacent counties. According to American artistGeorge Caleb Bingham, who described the order as "imbecilic" and was a resident of Kansas City at the time, one could see the "dense columns of smoke arising in every direction", symbolic of what he termed "a ruthless military despotism which spared neither age, sex, character, nor condition". Because of the destruction carried out under the order, its legacy haunted Jackson County for decades after the war.
The coming of the railroads and the building of stockyards led to the rapid expansion of Kansas City in the late 19th century. During the 1920s and '30s, the city became a noted center forJazz andBlues music, as well as the headquarters ofHallmark Cards and the site ofWalt Disney's first animation studio. The county fared better than many during theGreat Depression, as local political bossThomas Pendergast worked to implement a $50,000,000 public works project that provided thousands of jobs. One of Pendergast's political protegés was a youngWorld War I veteran from Independence,Harry S. Truman, who had been his nephew's commanding officer in the war. Truman was elected Presiding Judge (equivalent to a County Executive) of Jackson County with Pendergast support in 1926. He later was elected as aU.S. Senator from Missouri,Vice President and, in 1945, following the death ofFranklin D. Roosevelt, succeeded him to become the thirty-thirdPresident of the United States. Truman was also elected president in 1948 in his own right.
FollowingWorld War II, developers followed new highways and created subdivisions for new housing, which increasingly encroached on rural portions of the county. They provided housing for the nation's returning veterans and their young families. Independence,Blue Springs andLee's Summit underwent growth during this period, which continues to the present. Kansas City, on the other hand, suffered problems ofurban decay as jobs and families left the industrial city, problems common to many large American cities in the late 20th century.
In 2024, the statues of Andrew Jackson were voted about whether to remove as to not idolize a slave owner or not. The plaques added in 2021 to the statues to hopefully add context and support for keeping the statues,[12] wording it acknowledge Jackson was a slave owner and also supported theIndian Removal Act.[13]

The last Republican presidential candidate to carry the county wasRichard Nixon in1972, the only Republican to do so since 1932.John Ashcroft was the last Republican gubernatorial candidate in1988 andKit Bond for the Senate in1998.Tom Schweich is the last Statewide Republican candidate to win the county in his landslide victory for State Auditor in2014.
