The slogan "Peace at home, peace in the world" (Turkish: Yurtta sulh, cihanda sulh, rendered today as Yurtta barış, dünyada barış due to Atatürk's language reforms[citation needed]) was first pronounced by Mustafa Kemal Atatürk on 20 April 1931 to the public during his tours of Anatolia.
The slogan was at the heart of a dispute causing the Turkish Super Cup final between Galatasaray and Fenerbahçe in Saudi Arabia in December 2023 to be postponed.
As the cup was being held on the centennial of the Turkish Republic, the match was thought to be of special national importance.
Saudi authorities contest that it was agreed that no political slogans should be raised, and entry to the stadium should be in the official jerseys approved by the Turkish Football Federation.
However, the words and images of Atatürk as well as the National Anthem were never considered political by either club, and since they had never asked TFF for permission for such things, this caused a major misunderstanding.
