Which status did texas officially have after the treaty of colorado?

The Treaty of Guadalupe Hidalgo, signed on February 2, 1848, ended the Mexican-American War in favor of the United States. The war had begun almost two years earlier, in May 1846, over a territorial dispute involving Texas. The treaty added an additional 525,000 square miles to United States territory, including the land that makes up all or parts of present-day Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming. Mexico also gave up all claims to Texas and recognized the Rio Grande as America’s southern boundary.
