National flag - Flag of Liechtenstein

The flag of Liechtenstein (Flagge Liechtensteins) consists of two horizontal blue and red bands charged with a gold crown at the canton. Adopted in 1921 after being officially enshrined into the nation's constitution, it has been the flag of the Principality of Liechtenstein since that year. The crown was added to the flag in 1937 after the country found out at the Summer Olympics held the previous year that their flag was identical to the flag of Haiti.

Liechtenstein was formed in 1719 as a principality within the Holy Roman Empire, and gained complete independence in 1866. Within this period, the colours blue and red were selected to feature on the flag, instead of the gold and red on the coat of arms that would have customarily been employed instead. These new livery colours were first utilized by Prince Joseph Wenzel I in 1764.

A new constitution for the Principality was formulated and proclaimed in October 1921. It made the blue and red banner the national flag by granting it "official status". Fifteen years later, during the 1936 Summer Olympics, the country came to the realization that its flag was identical to the flag of Haiti, even though Haiti did not participate in the Olympics that year. Because of this finding, the government added the prince's crown to the canton. This change served two purposes – to signify Liechtenstein's position as a principality, and to distinguish its flag from Haiti's. This modified design was adopted on June 24, 1937.

The colors and symbols of the flag carry cultural, political, and regional meanings. The blue represents the sky, while red alludes to the "evening fires" that are lit inside houses throughout the country. The crown – whose colour is disputed – epitomizes the "unity of the people and their prince." While The World Factbook and Reuters describe it as gold in colour, other sources – such as Whitney Smith in the Encyclopædia Britannica – describe it as yellow.

Liechtenstein, officially the Principality of Liechtenstein (Fürstentum Liechtenstein), is a doubly landlocked German-speaking microstate in Alpine Central Europe. The principality is a constitutional monarchy headed by the Prince of Liechtenstein.

Liechtenstein is bordered by Switzerland to the west and south and Austria to the east and north. It is Europe's fourth-smallest country, with an area of just over 160 km2 and a population of 37,877. Divided into 11 municipalities, its capital is Vaduz, and its largest municipality is Schaan. It is also the smallest country to border two countries.
