In 1903, a joint court between Great Britain and Canada established the border with southeastern Alaska.  While Webster and Ashburton agreed to call for a definitive end to the slave trade on the high seas, they agreed to pass the creole fall of 1841 in the Caribbean, which was then controversial. In November 1841, a slave revolt over the American Creole brigade, part of the coastal slave trade, forced the ship to Nassau. Officials in the Bahamas eventually emancipated the 128 slaves who decided to stay in Nassau, as Britain abolished slavery in its colonies effective 1834.  The United States first demanded the return of slaves and then compensation. An agreement was reached in 1855 as part of a much larger claim contract of 1853, covering the claims of both nations until 1814. In 1823, when the last bonds issued in the United Kingdom and the Netherlands to finance the purchase were paid interest by the U.S. Treasury, the total expenditure for Louisiana was $23,313,567.73. As if they were sympathizers with President Jefferson`s assertions, Louisiana`s borders expanded and adapted over time, until they stretched from the Gulf of Mexico to British America (now In Canada) and from the Mississippi River to the Rockies. Today, it is estimated that the land forming Louisiana Purchase will cover between 850,000 and 885,000 square miles.
The territories that were once part of Louisiana make up a total of six states: Arkansas, Iowa, Missouri, Nebraska, Kansas and Oklahoma; most states of Louisiana, Minnesota, North Dakota, South Dakota, Montana, Wyoming and Colorado; and sections of New Mexico and Texas. At the time of the purchase, small portions of the Canadian provinces of Alberta and Saskatchewan were also suspected of being part of the transaction. It should be noted that, although both Great Britain and the United States claimed the entire country of Oregon, the two parties largely expected to share the territory; Both could reasonably expect to acquire the entire Oregon Country. To the east of the continental chasm, the United States and Great Britain had agreed on a border west of the Great Lakes at the 49th parallel. Almost from the beginning of the Oregon discussions, the British expected that this boundary would continue west of the Columbia River and then follow that river to the ocean. So they were prepared to leave everything in the United States south of the 49th parallel, then south and east of the Columbia River.
