[1] The star and crescent design appears on Ottoman flags beginning in the late 18th or early 19th century.

The white star and crescent moon on red as the flag of the Ottoman Empire were introduced in 1844.

[4] After the declaration of the Republic of Turkey in 1923, the new administrative regime maintained the last flag of the Ottoman Empire.

The colours approximation is listed below: The specification below, given by Turkish Flag Law, implies that the distance between (the left edge of) the inner circle of the crescent and a vertical line connecting the two pointed ends of the crescent is 279⁄800 G = 0.34875 G; thus, the left point of the star intrudes about 0.0154 G beyond that line.

The Beştepe Presidential Complex, Parliament, ministries, schools, military, councils, governors buildings, muhtar's offices, bridges, airports, and every state owned building in the country features one or more flags of Turkey.

Along with uniforms several emblems and patches display the flag with prominence or minor alteration.

On other occasions the public uses the flag heavily when protesting or commemorating certain events or deaths respectively.

The flag may also be presented at half staff in mourning of tragic events or important days.
