Editing Jackson County, Missouri (section)

===Early years===
Jackson County was long home to members of the indigenous [[Osage Indians|Osage]] tribe, who occupied this territory at the time of European encounter. The first known European explorers were [[France|French]] [[Animal trapping|trapper]]s who used the [[Missouri River]] as a highway for explorations and trading with regional [[Native Americans in the United States|Native American]] tribes. Jackson County was claimed as a part of the territory of [[New France]], until 1763 and the [[Great Britain|British]] victory in the [[French 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 the [[Third Treaty of San Ildefonso]] to return its [[Louisiana 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 the [[Louisiana Purchase]] of 1803.

Operating on behalf of President [[Thomas Jefferson]], explorers [[Meriwether Lewis]] and [[William Clark (explorer)|William Clark]] passed through Jackson County on their notable [[Lewis and Clark Expedition]] in 1804, to survey peoples, property and resources of the [[Louisiana Territory]]. Among other items, their report indicated a "high, commanding position" along the river within the current boundaries of Jackson County; in 1808 [[Fort 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 of [[Missouri]]. Jackson County was organized on December 15, 1826, and named for [[Andrew Jackson]], [[U.S. Senator]] from Tennessee and military hero of the [[War of 1812]], who would ascend to the [[President of the United States|Presidency]] shortly after, in 1829.<ref>{{cite book | url=https://archive.org/details/bub_gb_RfAuAAAAYAAJ | title=How Missouri Counties, Towns and Streams Were Named | publisher=The State Historical Society of Missouri | author=Eaton, David Wolfe | year=1916 | pages=[https://archive.org/details/bub_gb_RfAuAAAAYAAJ/page/n74 177]}}</ref><ref>{{cite book | url=https://archive.org/details/bub_gb_9V1IAAAAMAAJ | title=The Origin of Certain Place Names in the United States | publisher=Govt.

However, the rapid increase in westward exploration and expansion ultimately resulted in Independence becoming the starting point for three of the great Westward Trails: the [[Santa Fe Trail]], the [[Oregon Trail]], and the [[California Trail]]. Following the [[American 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 the [[River Market]] district). The area outside Westport Landing was renamed in 1839 as the "Town of Kansas", after the local [[Kaw (tribe)|Kanza 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.
