The flag with a crescent and a star on a red background was accepted as the official flag of the empire in 1793 for the first time in the Ottomans. However, the star on this flag was eight corners. This flag was used as the official and public symbol of the Ottoman Empire. The eight-pointed star in the flag meant victory.
During the reign of the first Sultan Abdülmecid Han in 1842, it was decided that the star had five corners and the shape of the Ottoman flag became definite. Five-pointed star represents human. This flag was shaped in 1936 by the “Turkish Flag Law” of the Republic of Turkey and was accepted as the national flag of Turkey. With the “Turkish Flag Law” numbered 2893 on September 22, 1983, flag criteria were determined and the flag became final. There are various myths about the story of the Turkish flag. This is first myth:
The night after the war in Kosovo in 1448, when the Ottoman Empire suffered a heavy defeat of its enemies, the crescent and star appearing side by side on the blood lake formed on the battlefield. Thus, Sultan Murad II began to use this symbol among the state flags. But; It is not possible for the Turkish flag to be formed after the 1st Kosovo war. Jupiter is the planet that is not any star that came alongside the crescendo that night. But some say this is after the second Kosovo war, which is wrong because the moon is in the new moon that day and has not laid it in the sky in any way. The picture below shows the image of the moon and the nearest jupiter in that date.
