Texas Louisiana-American Annexation Treaty of 1848?

Answer 1

A quick search with Google brings up a lot of posts proclaiming this, but no reference what so ever to this "treaty" in any law library or archive.

So what would the facts be?

First here are the dates of admission into the United States of the areas in question.

Louisiana Apr 30, 1812 Arkansas Jun 15, 1836 Texas Dec 29, 1845 Oklahoma Nov 16, 1907
Second, you do not annex states, you annex territories. The Louisiana Purchase was signed into effect in 1803. This annexed the territories that would become Arkansas, Missouri, Iowa, Oklahoma, Kansas, Nebraska, parts of Minnesota that were west of the Mississippi River, most of North Dakota, nearly all of South Dakota, northeastern
New Mexico, the portions of Montana, Wyoming, and Colorado east of the Continental Divide, and Louisiana west of the Mississippi River, including the city of New Orleans. (The Oklahoma Panhandle, and southwestern portions of Kansas and Louisiana were still claimed by Spain at the time of the Purchase.)

The Republic of Texas was supposed to be annexed in October 1845 as a Treaty of Annexation was the requirement in order to annex a sovereign nation. Texas became a state in December 1845 after statehood was granted by the U.S. Government, however, after research at the national archives of the United States and the state Capital of Texas, no Treaty of Annexation has ever been found and no vote by the people of Texas for Annexation was ever held.

Third, Right to secede (from Texas Annexation)

Neither the ordinance of annexation nor the joint resolution included provisions giving Texas the right to secede.[15] In its decision in Texas v. White in 1869, the United States Supreme Court ruled that Texas' secession in 1861 had been illegal. The Court held that "[t]he Constitution, in all its provisions, looks to an indestructible Union, composed of indestructible States." The court did allow that divisibility might be possible "through revolution, or through consent of the States."[16].

Fourth, the only treaty in 1848 involving any of the states mentioned is the Treaty of Guadalupe Hidalgo, which fully ended the Mexican-American War.

The only other treaties created in 1848 are 3 treaties with Native American tribes: the 1848 Treaty with the Pawnee, the 1848 Treaty with the Menominee and the 1848 Treaty with the Stockbridge Tribe.

So given these facts, there is really only one correct answer: These treaties do not exist.
