All 193 member states and 2 observer states of the United Nations, in addition to several de facto states, represent themselves with national flags. National flags generally contain symbolism of their respective state and serve as an emblem which distinguishes themselves from other states in international politics. National flags are adopted by governments to strengthen national bonds and legitimate formal authority. Such flags may contain symbolic elements of their peoples, militaries, territories, rulers, and dynasties. The flag of Denmark is the oldest flag still in current use as it has been recognized as a national symbol since the 14th century.
