Almost all the equestrian statues in Turkey portray Mustafa Kemal Atatürk (1881–1938), who is credited for being the founder of the Republic of Turkey. His surname, Atatürk (meaning ‘Father of the Turks’), was granted to him in 1934 and forbidden to be used by any other person by the Turkish parliament. Atatürk was a military officer during World War I. Following the defeat of the Ottoman Empire in that conflict, he successfully led the Turkish National Movement in the Turkish War of Independence. Having established a provisional government in Ankara, he defeated the forces sent by the Allies. Atatürk then embarked on a programme of political, economic and cultural reforms, seeking to transform the former Ottoman Empire into a modern and secular nation-state. Under his leadership, thousands of new schools were built, primary education was made free and compulsory, and women were given equal civil and political rights, while the burden of taxation on peasants was reduced.
Turkey honours Atatürk with many memorials throughout the country. I identified at least nine different equestrian statues of Atatürk in Turkey (and one in Japan), but I would not be at all surprised if there are many more.
