The Constitution of Norway, adopted on May 17, 1814, is one of the oldest written constitutions still in use today. It establishes Norway as a constitutional monarchy and outlines the structure of government, including the separation of powers among the executive, legislative, and judicial branches. The constitution guarantees fundamental rights and freedoms for its citizens, such as freedom of speech, assembly, and religion. It has undergone several amendments to adapt to changing societal values and political needs, ensuring that it remains relevant in contemporary Norway.
