State constitutions are legal documents that outline the fundamental principles and framework of government for each of the 50 U.S. states. They establish the structure of state government, define the powers of various branches, and protect the rights of citizens. Each state constitution can vary significantly, reflecting the unique history and values of the state. In addition to outlining government structure, state constitutions often include provisions for individual rights, similar to the U.S. Constitution. They can be amended through specific processes, allowing states to adapt to changing needs and circumstances. This flexibility helps ensure that state governments remain responsive to their citizens.
