The Flag of Serbia consists of three horizontal stripes: red at the top, blue in the middle, and white at the bottom. This tricolor design is rooted in the Pan-Slavic colors, symbolizing the unity of Slavic nations. The flag was officially adopted in 2004, although its colors have been used since the 19th century. In the left part of the flag, there is a coat of arms featuring a double-headed eagle, which represents the sovereignty of Serbia. The eagle is white on a red background and is accompanied by a smaller shield that displays a cross and four firesteels, symbolizing the country's heritage and history.
