The Circassian flag (or the Flag of Adygea) is the national flag of the Circassians. It consists of a green field charged with twelve gold stars, nine forming an arc resembling a bow and three horizontal, also charged with three crossed arrows in the center. Seferbiy Zaneqo, a Circassian diplomat, is the designer of the flag. Every year, April 25 is celebrated as the Circassian flag day by Circassians. The green represents nature and Islam. The golden colour represents a bright future in peace and the plentiful harvest of grain and wheat. There are twelve stars, representing the twelve provinces of Circassia. There are three arrows, a reference to Adyghe Xabze in which they would mean "peace if you are my friend, war if you attack me". An invasion of Circassia by Russia started in 1763, and since then, the Circassians have been fighting the Russo-Circassian War in defense of their territory. The Treaty of Adrianople was signed on 14 September 1829, which stated that the Ottoman Empire recognized Circassia as Russian territory. Most Circassian leaders believed the treaty was a hoax, a strategy of the Russians, as they believed that the Ottoman Empire would never abandon the Circassians. It was decided to send a delegation to the Ottoman sultan to examine the accuracy of the news. Seferbiy Zaneqo was chosen as one of the delegates. Their mission was to meet with the Ottoman caliph to clarify the matter and receive a blessing. However, the Russian ambassador started pressuring the sultan to arrest them, and following this, the other delegates returned the Circassia while Zaneqo stayed. During this time, Zaneqo was injured during a demonstration against Russian Imperialism, and was hospitalised. When a Circassian man, Muhammad Selkhur, visited him, Zaneqo presented a folded paper, and clarified that it is a prototype for a Circassian unity flag, and that during his long hospitalization, he thought considerably about a symbol for the Circassian unity and he concluded on the contents of the paper.
