Liechtenstein’s flag is the European flag with a gold crown in the upper-left corner on a blue-and-red horizontal bicolour.
The blue and red colours were first used by Prince Joseph Wenzel I in 1764 and became the flag’s colours in 1852. Liechtenstein’s 1921 constitution gave the blue-and-red design official status.
The crown was added in 1937 after Liechtenstein discovered that its flag closely matched Haiti’s civil flag at the 1936 Summer Olympics. The crown distinguishes the two designs, although Haiti’s flag has different national symbolism and proportions. Liechtenstein’s crown was modified again in 1982.
Liechtenstein became a principality of the Holy Roman Empire in 1719 and gained full independence from the German Confederation in 1866. The blue is commonly associated with the sky, while the red recalls evening fires traditionally lit inside homes. The flag’s modern proportions are 3:5.
