We, the people of the State of Tennessee, waiving any expression of opinion as to the abstract doctrine of secession, but asserting the right, as a free and independent people, to alter, reform, or abolish our form of government in such manner as we think proper, do ordain and declare that all the laws and ordinances by which the State of Tennessee became a member of the Federal Union of the United States of America are hereby abrogated and annulled, and that all the rights, functions, and powers which by any of said laws and ordinances were conveyed to the Government of the United States, and to absolve ourselves from all the obligations, restraints, and duties incurred thereto; and do hereby henceforth become a free, sovereign, and independent State.
“Texas abandoned her separate national existence and consented to become one of the Confederated Union to promote her welfare, insure domestic tranquility and secure more substantially the blessings of peace and liberty to her people. She was received into the confederacy with her own constitution, under the guarantee of the federal constitution and the compact of annexation, that she should enjoy these blessings. She was received as a commonwealth holding, maintaining and protecting the institution known as negro slavery— the servitude of the African to the white race within her limits— a relation that had existed from the first settlement of her wilderness by the white race, and which her people intended should exist in all future time. Her institutions and geographical position established the strongest ties between her and other slave-holding States of the confederacy. Those ties have been strengthened by association.” - Texas Declaration of the Causes of Secession.
