national flag containing three equal red, blue, and white horizontal stripes and, near the hoist, the Serbian coat of arms. Its width-to-length ratio is 2 to 3.

The design of the Serbian flag dates to Serbia's revolt against Ottoman rule in 1804, when it adopted the white-blue-red tricolour flag of Russia (Russia, flag of) but with the order of the stripes rearranged. Eventually these became known as the pan-Slavic (Slav) colours, and they were used by many other Slavic countries in Europe, particularly during the revolutionary movements of 1848. The Ottoman sultan officially recognized the Serbian flag in 1835 and also in 1869; the country became independent in 1878. In 1882 Serbia established a state flag consisting of the red-blue-white tricolour with the royal Serbian coat of arms. The arms showed a red shield bearing a white cross with a Cyrillic C in each corner—the letters popularly thought to mean, “Samo sloga Srbina spasava” (“Only unity will save the Serbs”). The shield also bore historic dynastic symbols: a white double-headed crowned eagle and a fleur-de-lis next to each talon.

Following World War I, Serbia, as part of the Kingdom of Serbs, Croats, and Slovenes (later renamed Yugoslavia), had no flag of its own but flew the Yugoslav blue-white-red tricolour (first hoisted on Oct. 31, 1918, shortly before the establishment of the kingdom). The country was dissolved during World War II but was reestablished as a federation in 1945; a yellow-bordered red star was added to the centre of the former Yugoslav flag. The country's constituent republics were also allowed flags of their own, and Serbia adopted the Serbian red-blue-white tricolour, bearing a yellow-bordered red star in the centre, in 1947.
