why did texas originally joined the confederate states of america
Texas in the American Civil War The U.S. state of Texas declared its secession from the United States of America on February 1, 1861, and joined the Confederate States on March 2, 1861, after it replaced its governor, Sam Houston, when he refused to take an oath of allegiance to the Confederacy. As with those of other States, the Declaration was not recognized by the United States government at Washington. Some Texan military units fought in the Civil War east of the Mississippi River, but Texas was most useful for supplying soldiers and horses for Confederate forces. Texas' supply role lasted until mid-1863, after which time Union gunboats controlled the Mississippi River, making large transfers of men, horses or cattle impossible. Some cotton was sold in Mexico, but most of the crop became useless because of the Union naval blockade of Galveston, Houston, and other ports.
History of Texas (1845–1860) In 1845, the Republic of Texas was annexed to the United States of America, becoming the 28th U.S. state. Border disputes between the new state and Mexico, which had never recognized Texas independence and still considered the area a renegade Mexican state, led to the Mexican–American War (1846–1848). When the war concluded, Mexico relinquished its claim on Texas, as well as other regions in what is now the southwestern United States. Texas' annexation as a state that tolerated slavery had caused tension in the United States among slave states and those that did not allow slavery. The tension was partially defused with the Compromise of 1850, in which Texas ceded some of its territory to the federal government to become non-slave-owning areas but gained El Paso
