Anew constitution for the Principality was formulated and proclaimed in October 1921.[1][4] It made the blue and red banner the national flag by granting it "official status".[1] Fifteen years later, during the1936 Summer Olympics, the country came to the realization that its flag was identical to theflag of Haiti (Haititook part in the Opening Ceremony but its sole athlete did not compete). Because of this finding, the government added the prince's crown to the canton.[1][5][6] This change served two purposes – to signify Liechtenstein's position as a principality, and to distinguish its flag from Haiti's.[5][7] This modified design was adopted on 24 June 1937.[7] A design with a modified crown was adopted on 30 June 1982.
The colours and symbols of the flag carry cultural, political, and regional meanings. The blue represents thesky, while red alludes to the "evening fires" that are lit inside houses throughout the country.[1] The crown is gold[5][6] or yellow[1] in colour.[7]
