Who were the tribes that composed the army of the confederates

The American Civil War saw Native American individuals, bands, tribes, and nations participate in numerous skirmishes and battles.[2] Native Americans served in both the Union and Confederate military during the American Civil War. They were found in the Eastern, Western, and Trans-Mississippi Theaters. At the outbreak of the war, for example, the majority of the Cherokees sided with the Union, but soon after allied with the Confederacy.[3] Native Americans fought knowing they might jeopardize their sovereignty, unique cultures, and ancestral lands if they ended up on the losing side of the Civil War.[2][3] 28,693 Native Americans served in the Union and Confederate armies during the Civil War, participating in battles such as Pea Ridge, Second Manassas, Antietam, Spotsylvania, Cold Harbor, and in Federal assaults on Petersburg.

Explanation:

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
