24 March 1663
[24 March 1662/1663] King Charles II created Carolina from the earlier range of Virginia territory and granted it as a proprietary colony to eight of his supporters. Limits were: on the north, the north end of Lucke Island and the parallel of 36 degrees north latitude; on the west, the Pacific Ocean; and on the south, the St. Marys River and, from that river westward, the parallel of 31 degrees north latitude. Carolina included all of present Alabama and Mississippi north of 31 degrees north latitude. (Swindler, 7:357-358)
30 June 1665
King Charles II granted a new charter to the proprietors of Carolina, expanding jurisdiction to north and south. New boundaries were: on the north, a line from the north end of Currituck River westward to "Wyonoak" Creek and thence due west along the parallel of 36 degrees, 30 minutes north latitude; on the west, the Pacific Ocean; and on the south, the parallel of 29 degrees north latitude. Carolina included all of present Alabama and Mississippi. (Swindler, 7:375)
8 April 1699
The French established the first European settlement within the present boundaries of Mississippi at Fort Maurepas, near present Ocean Springs on the Gulf of Mexico. (Rowland, Old Biloxi, 10; Skates, 23-25)
1719
In 1719, the French commander at New Orleans and the Spanish commander at Pensacola agreed to recognize the Perdido River as the boundary between their jurisdictions, Louisiana and Florida, and their home governments acquiesced in the arrangement. (Cox, 8)
9 June 1732
King George II created Georgia from South Carolina and granted it as a proprietary colony in trust for 21 years. Boundaries were: on the north, the Savannah River; on the south, the Altamaha River; and on the west, the Pacific Ocean. Georgia included the northern portions of present Alabama and Mississippi. (Paullin, 27, pl. 42; Swindler, 2:437)
10 February 1763
The Treaty of Paris, ending the Seven Years War between Great Britain (the victor) and France and Spain, formally transferred Florida to the British and implicitly set the Mississippi River as a new western limit for the British colonies, including Georgia, whose charter bounds had technically extended to the Pacific Ocean. (Cappon, Petchenik, and Long, 1)
7 October 1763
King George III, by his Proclamation of 1763, created three new royal provinces and settled a dispute between two older ones. Relevant provisions: West Florida was created to cover the territory west of the Apalachicola River, south of 31 degrees north latitude, and east of the Mississippi River, Iberville River, and Lake Pontchartrain, including the southern parts of present Louisiana, Mississippi, Alabama, plus part of Florida. Georgia gained the territory south of the Altamaha River and north of Florida, thereby settling a dispute between Georgia and South Carolina and confirming Georgia's claim to all of present Mississippi and Alabama north of 31 degrees north latitude. (Cappon, Petchenik, and Long, 1, 77; Shortt and Doughty, 119-120)
July 1764
In the commission to West Florida's first governor, Great Britain redefined West Florida, extending its limits northward to a line running due east from the junction of the Yazoo and Mississippi Rivers to the Chattahoochee River; this implicitly reduced the western extent of Georgia and added Natchez and much of present Mississippi and Alabama to West Florida. (Cappon, Petchenik, and Long, 87)
8 May 1781
Spain captured Pensacola, successfully concluding a campaign (started in August 1779) to conquer West Florida from Britain during the War of the American Revolution. (Cappon, Petchenik, and Long, 53-54)
3 September 1783
Commissioners from Great Britain and the United States signed the Treaty of Paris, ending the War of the American Revolution, recognizing American independence, and generally defining U.S. boundaries as including the Mississippi River on the west and the Floridas on the south (ratifications exchanged 12 May 1784). Great Britain ceded East and West Florida to Spain by a separate Treaty of Paris, but the boundaries of the Floridas were not specified in it. (Parry, 48:481, 487, 491-492; Van Zandt, 12)
29 July 1784
Spain claimed most of the southwestern United States (north of West Florida, east of the Mississippi River, south of the Tennessee and Hiwassee Rivers, and west of the Flint River) based on its conquest of British West Florida and the lower Mississippi during the War of the American Revolution. The United States insisted upon the parallel of 31 degrees north latitude, specified in its 1783 peace treaty with Great Britain, as its southern boundary. Neither side actually controlled the interior. (Cappon, Petchenik, and Long, 14, 74, 87; Whitaker, facing 68)
7 February 1785
The state of Georgia claimed the area north of 31 degrees north latitude, based on its colonial charter and created BOURBON (Ga., extinct) in present Mississippi. (Rowland, Miss. Terr. Arch., 503-505; Watkins and Watkins, 304-305)
1 February 1788
BOURBON (Ga.) was eliminated by the state of Georgia. (Watkins and Watkins, 370-371)
27 October 1795
Pinckney's Treaty with Spain (ratified 25 April 1796) settled the U.S.-Florida boundary along the parallel of 31 degrees north latitude from the Mississippi River eastward to the Chattahoochee River, downstream to the mouth of the Flint River, eastward on a straight line to the head of the St. Marys River, and downstream to the Atlantic Ocean. (Parry, 53:9, 12-13; Van Zandt, 22)
7 April 1798
The United States created Mississippi Territory in parts of present Mississippi and Alabama. Boundaries were: on the west, the Mississippi River; on the north, a line running due east from the mouth of the Yazoo River to the Chattahoochee River; on the east, the Chattahoochee River; and on the south, the parallel of 31 degrees north latitude. Georgia continued to claim this area under its colonial charter, and the federal act said that creation of the territory would not impair Georgia's claim. (U.S. Stat., 1:549-550)
2 April 1799
ADAMS and PICKERING (now JEFFERSON) created by Mississippi Territory from non-county area; ADAMS and PICKERING included territory in present Mississippi and Alabama. (Rowland, Miss. Terr. Arch., 126-128; Toulmin, Statutes, ch. 1/pp. 2-3)
4 June 1800
WASHINGTON (Ala.) created by Mississippi Territory from ADAMS and PICKERING (now JEFFERSON); WASHINGTON (Ala.) included territory in present Mississippi and Alabama. ADAMS and PICKERING were eliminated from present Alabama. (Rowland, Miss. Terr. Arch., 238-239; Toulmin, Statutes, ch. 1/pp. 3-4)

30 January 1802
ADAMS gained from JEFFERSON. CLAIBORNE and JEFFERSON lost to creation of Non-County Area 1 when the Choctaw Indian boundary was implicitly adopted as the eastern limit of the two counties. This eliminated the overlap of CLAIBORNE with WASHINGTON (Ala.) and eliminated CLAIBORNE from present Alabama. (Miss. Terr. Stat., p. 90)
WILKINSON created by Mississippi Territory from ADAMS. (Miss. Terr. Stat., p. 89)
24 April 1802
Georgia and the United States made a two-part agreement: the United States ceded to Georgia all claims to any territory south of North Carolina and west of the Appalachian watershed that it received in 1787 from South Carolina; Georgia ceded to the United States all territory south of North Carolina and Tennessee, east of the Mississippi River, north of the parallel of 31 degrees north latitude and west of the present western limit of Georgia, that is, much of present Mississippi and Alabama. This area became unorganized federal territory. (Paullin, 83; Van Zandt, 100; Terr. Papers U.S., 5:142-143)
12 March 1803
CLAIBORNE gained from JEFFERSON. A mistake in the description would have enlarged CLAIBORNE eastward to Georgia, thereby overlapping Non-County Area 1 and WASHINGTON (Ala.) [mistake corrected 7 February 1807; no change]. (Miss. Terr. Stat., p. 90)
30 April 1803
The United States purchased Louisiana by treaty from France, taking formal possession 20 December 1803; boundaries were not clearly defined but unquestionably included the western half of the Mississippi drainage basin. The United States took advantage of the ambiguous description of the territory to claim all of West Florida west of the Perdido River (southern portions of present Alabama and Mississippi) as part of the 1719 de facto definition of Louisiana, even though Spain actually governed the area. (Cox, facing 2, 84-101; Parry, 57:27, 30-31)
26 March 1804
The United States created Orleans Territory from that portion of Louisiana south of the parallel of 33 degrees north latitude, west of the Mississippi River, and south of Mississippi Territory east of the river to the Perdido River; this included part of West Florida between the Mississippi and Perdido Rivers (including the southern portion of present Mississippi), claimed by the United States as part of Louisiana but actually governed by Spain.
