The purpose of the state constitution is to determine where the power and authority lie within the state’s government. The state constitution also provides basic freedoms for its citizens, while limiting the power of the government. These are elements of the U.S. Constitution that many state constitutions in the United States also include.

The Texas Constitution is similar to the U.S. Constitution for several reasons. First, both documents have a preamble, bill of rights, and articles that create three branches of government. Second, the idea of federalism exists in both constitutions, and third, both documents reflect similar constitutional principles.
