The flag of Turkey is a red flag with a white crescent moon and a white five-pointed star. The red color represents the blood of the Turkish people who have fought for their country's independence, while the white crescent moon and star are symbols of Islam, the dominant religion in Turkey.
The flag was adopted by the Republic of Turkey in 1923, after the fall of the Ottoman Empire and the establishment of the modern Turkish state. The design of the flag is based on the flag used by the Ottoman Empire, which used the same symbols but in a different color scheme. The flag is an important national symbol for the people of Turkey and is often displayed at official ceremonies and events, as well as on public buildings and other sites throughout the country.
