The Louisiana Purchase was the acquisition of the territory of Louisiana by the United States from the French First Republic in 1803. This consisted of most of the land in the Mississippi River's drainage basin west of the river. In return for fifteen million dollars, or approximately eighteen dollars per square mile, the United States nominally acquired a total of 828,000 sq mi in Middle America. However, France only controlled a small fraction of this area, most of which was inhabited by Native Americans; effectively, for the majority of the area, the United States bought the preemptive right to obtain Indian lands by treaty or by conquest, to the exclusion of other colonial powers.

The Militia of the Territory of Arkansas, commonly known as the Arkansas Militia, was the forerunner of today's Arkansas National Guard. The current Arkansas Army National Guard traces its roots to the creation of the territorial militia of the District of Louisiana in 1804. As the District of Louisiana evolved into the Territory of Missouri and the first counties were organized, regiments of the Missouri territorial militia were formed in present-day Arkansas. Territorial governors struggled to form a reliable militia system in the sparsely populated territory. When the Arkansas Territory was formed from the Missouri Territory, the militia was reorganized, gradually evolving from a single brigade composed of nine regiments to an entire division composed of six brigades, each containing four to six regiments. The local militia organization, with its regular musters and hierarchy added structure to the otherwise loosely organized territorial society. The Territorial Militia was utilized to quell problems with the Indian Nations and was held in readiness to deal with trouble along the border with Mexico due to an ambiguous international border and during the prelude to the Texas War of Independence.
