History
On June 5, 1849, Denmark adopted its first constitution, making Denmark a constitutional monarchy and establishing democratic governance. The constitution abolished absolute monarchy and introduced a bicameral parliament system. This democratic milestone came after the European revolutions of 1848, when Denmark underwent significant political reforms. Constitution Day is one of the most celebrated holidays in Denmark, observed with flag-raising ceremonies, speeches, and family gatherings. The original constitution has been amended several times since, but remains the foundation of Danish democracy.
