|History of Arkansas|
The Territory of Arkansas, initially organized as the Territory of Arkansaw,  was an organized incorporated territory of the United States that existed from March 2, 1819, until June 15, 1836, when the final extent of the territory was admitted to the Union as the State of Arkansas. 
Arkansaw Territory (later Arkansas Territory) was created from the portion of the Missouri Territory lying south of a point on the Mississippi River at 36 degrees north latitude running west to the St. Francis River, then followed the river to 36 degrees 30 minutes north latitude, then west to the territorial boundary. This included all of the present state of Oklahoma south of the parallel 36°30' north. The westernmost portion of the territory was removed on November 15, 1824, and a second westernmost portion was removed on May 6, 1828, reducing the territory to the extent of the present state of Arkansas.
Originally the western border of Missouri was intended to go due south to the Red River. During negotiations with the Choctaw in 1820, however, Andrew Jackson unknowingly ceded more of Arkansas territory. Then in 1824, after further negotiations, the Choctaw agreed to move farther west, but only by "100 paces" of the garrison on Belle Point. This resulted in the bend in the common border at Fort Smith, Arkansas.

- The name
Arkansas has been pronounced and spelled in a variety of fashions. The region was organized as the Territory of Arkansaw on March 2, 1819, but the final entent of the territory was admitted to the
Union as the State of Arkansas on June 15, 1836. The name was historically pronounced
//, and had several other pronunciation variants. In 1881, the
Arkansas General Assembly passed the following concurrent resolution (Arkansas Statutes, Title 1, Chapter 4, Section 105):
Whereas, confusion of practice has arisen in the pronunciation of the name of our state and it is deemed important that the true pronunciation should be determined for use in oral official proceedings.
And, whereas, the matter has been thoroughly investigated by the State Historical Society and the Eclectic Society of Little Rock, which have agreed upon the correct pronunciation as derived from history, and the early usage of the American immigrants.
Be it therefore resolved by both houses of the General Assembly, that the only true pronunciation of the name of the state, in the opinion of this body, is that received by the French from the native Indians and committed to writing in the French word representing the sound. It should be pronounced in three (3) syllables, with the final "s" silent, the "a" in each syllable with the Italian sound, and the accent on the first and last syllables. The pronunciation with the accent on the second syllable with the sound of "a" in "man" and the sounding of the terminal "s" is an innovation to be discouraged.
