The state constitutions were all revised after Reconstruction. In Texas, the Democrats wrote a Bill of Rights that should look familiar to all Americans. Here is the first one:

ARTICLE I.

Bill of Rights.
That the general, great and essential principles of liberty and free government may be recognized and established, we declare:

SECTION 1. Texas is a free and independent State, subject only to the Constitution of the United States; and the maintenance of our free institutions and the perpetuity of the Union depend upon the preservation of the right of local self-government unimpaired to all the States.

SEC. 2. All political power is inherent in the people and all free governments are founded on their authority, and instituted for their benefit. The faith of the people of Texas stands pledged to the preservation of a republican form of government, and, subject to this limitation only, they have at all times the inalienable right to alter, reform or abolish their government in such manner as they may think expedient.
