Istanbul Derby — Galatasaray vs Fenerbahçe

The Istanbul Derby between Galatasaray and Fenerbahçe is the most followed football fixture in a country of 85 million — drawing television audiences that peak at 25 million viewers in Turkey. The rivalry runs deeper than football: Galatasaray was founded by a student at the elite Galatasaray Lycée in 1905; Fenerbahçe was founded by Ottoman nationalists in 1907. The 2014 match at Şükrü Saracoğlu Stadium required 3,000 police officers and 15 mounted officers to prevent riots.
