Mexican Cession (i.e. Texas)
The US claimed what became the New Mexico territory during the Mexican-American War. It was primarily a linear western extension from Texas.
Texas was originally part of Mexico. I believe Texas wanted to be its own country. The US claimed Texas after the war between the US and Mexico.
Oklahoma Territory
Oklahoma Territory
Mexico claimed but never occupied, explored or tried to settle those areas which were a part of the Comancheria and lost them by default when they sought to become a part of the United States.
Because at the time, Texas was also a Mexican territory.
True! (:

Mexico Texas was originally part of the Spanish holdings in the "New World." When Mexico won its independence from Spain, it claimed Texas as part of Mexico. Texas attracted many American settlers who eventually declared their independence from Mexico and set up the Repubic of Texas, an independent nation. Finally, in 1845, Texas joined the United States as the 28th state.
Spain claimed Texas. It was in 1492. ha ha ha
The United States never had to fight a war to gain control of Texas and other southwest territories, such as the California territory. Texas was annexed in a time of peace in 1845 by the US; however, this provoked anger from the Mexican government which still did not recognize the independence of the Republic of Texas, and claimed it as still their own territory, albeit a "troublesome one." As a result of the US annexation of Texas, the Mexican-American War broke out.
