Following the abolition of the Sultanate on 1 November 1922, the Ottoman coat of arms was no longer used and the crescent and star became Turkey's de facto national emblem.

Three years later, in 1925, Ministry of Education opened a contest for determining another official coat of arms and artist Namık İsmail's design won.

The shield was surrounded by a garland of wheat and oak leaves, with a medallion depicting Ottoman alphabet letters T and C for Türkiye Cumhuriyeti, Republic of Turkey.

[5][6] A circular section of the red flag of Turkey containing the white crescent and star is used in the current emblems of a number of Turkish ministries and governmental institutions, in the emblem of the Grand National Assembly, and as the flag badge on the uniforms of Turkish national sports teams and athletes.

[9] A variant of this oval escutcheon (containing the gold-tone text Türkiye Cumhuriyeti Büyükelçiliği) is used by the Turkish embassies.
