The New Hampshire State Constitution is the foundational legal document that outlines the structure and function of the state government. Adopted in 1784, it is one of the oldest state constitutions still in use today. The constitution establishes the separation of powers among the legislative, executive, and judicial branches, ensuring a system of checks and balances. Additionally, the constitution includes a Bill of Rights, which guarantees individual freedoms and protections for the citizens of New Hampshire. This document has been amended several times to reflect changing values and needs, but its core principles remain central to the governance of the state.
