Denmark transitioned into a constitutional monarchy on June 5, 1849, when King Frederik VII signs the first democratic constitution (Grundloven), which had been approved by the Constitutional Assembly on May 25, 1849.
This event, known as Constitution Day (Grundlovsdag), marked the end of Denmark's absolute monarchy and the establishment of a parliament (Rigsdagen), transitioning the crown into a ceremonial Head of State with limited and defined powers.
