History
Galatasaray SK was founded in October 1905 (the exact day is disputed, but is traditionally accepted as "17 Teşrinievvel 1321[22][non-primary source needed]" according to the Islamic Rumi calendar, which corresponds to 30 October 1905 (according to the Gregorian calendar) by Ali Sami Yen and other students of Galatasaray High School (a high school in Istanbul which was established in 1481) as a football club. Ali Sami Yen, who became Galatasaray SK's first president and was given the club's membership number "1", was the son of Şemseddin Sami (Frashëri), an Ottoman writer, philosopher, and playwright of ethnic Albanian origin, and a prominent figure of the Rilindja Kombëtare, the National Renaissance movement of Albania.
The club's first match was against Cadi Keuy FRC and Galatasaray won this game with a score of 2–0. There were discussions about the club's name, in which some suggested Gloria (victory) and others Audace (courage), but it was decided that its name would be Galatasaray.
According to researcher Cem Atabeyoğlu, Galatasaray took its name from one of its first matches. In that match, Galatasaray won 2–0 over Rûm club and the spectators called them "Galata Sarayı Efendileri" (in English: Gentlemen of Galata (City) Palace), and, after this event, they adopted that name and started to call their club "GalataSaray". In 1905, during the era of the Ottoman Empire, there were no laws for associations so the club could not be registered officially, but after the 1912 Law of Association, the club registered legally.
Along with the founder Ali Sami Yen, the co-founders were the ones who were keen to do this sport, such as Asim Tevfik Sonumut, Reşat Şirvani, Cevdet Kalpakçıoğlu, Abidin Daver and Kamil.
At first, the colors of the Galatasaray Sports Club were red and white, which are the colors in the Turkish flag. However, the Turkish Republic was not founded at that time. Therefore, this inspiration caused repressive administration of the day feel uncomfortable and the administration hounded the footballers. For this reason, the colors were changed to yellow and dark blue till 1907. In 1908, new colors were chosen as red and yellow. Ali Sami Yen stated, "We were imagining brightness of yellow – red fire over our team and thinking that it would carry us from one victory to another."
While the football in Turkey began to fully develop, Galatasaray won ten more Istanbul League titles[citation needed] until 1952[citation needed]. Upon recognition of professional football in 1952, the first professional but non-national league of Turkey, Istanbul Professional League played between 1952 and 1959. Galatasaray won three of these seven titles.[citation needed]
Turkcell Super League, the top-flight professional league in Turkish nationwide football, and the most popular sporting competition in the country, formed in 1959. Galatasaray joined all seasons and won 22 league titles since then.
The Turkish Football Federation started to organize "Turkish Cup" (today it is organized with the name Ziraat Turkish Cup) in the 1962–63 season for Turkish clubs to qualify for the UEFA competitions. This is the only national cup competition in Turkey. Galatasaray joined all seasons and won 18 trophies since then.
