İstanbulspor

İstanbulspor Kulübü is a Turkish football and sports club founded by Istanbul High School students in 1926. In 2004–05, they were relegated from the Turkish Süper Lig to the TFF First League. For many decades, it was the fourth most famous and well-developed professional football club in Istanbul, coming after Beşiktaş, Galatasaray, and Fenerbahçe. After being bought by the Uzan family in 1990, it has been repossessed by the government and resold to third parties.
