Gradanski nogometni klub Dinamo Zagreb (English: Dinamo Zagreb Citizens' Football Club), commonly referred to as GNK Dinamo Zagreb or simply Dinamo Zagreb (pronounced [dinamo zaːɡreb]), is a Croatian professional football club based in Zagreb. The club is the successor of 1. HSK Gradanski, which had been founded in 1911, disbanded in 1945 and replaced by the newly founded Dinamo Zagreb. They play their home matches at Stadion Maksimir. They are the most successful club in Croatian football, having won twenty-two Prva HNL titles, sixteen Croatian Cups and six Croatian Super Cups. The club has spent its entire existence in top flight, having been members of the Yugoslav First League from 1946 to 1991, and then the Prva HNL since its foundation in 1993.
At the end of the World War II, the new communist government of Yugoslavia considered Croatian clubs like HSK Gradanski as fascist and nationalist, because they had operated under the former Independent State of Croatia, which was an Axis member during the war. As such, they were formally disbanded and, in 1945, FD Dinamo was founded as a club to act as an unofficial successor to HSK Gradanski, getting around the ruling party's disapproval. They entered the Yugoslav First League in its inaugural 1946–47 season, finishing as runners-up. In their second season in Yugoslav top flight in 1947–48 they finished as Yugoslav champions, which was their first major trophy. The club won three more league titles and seven Yugoslav Cups. Amid the breakup of Yugoslavia and formation of the Croatian football league system, Dinamo left the Yugoslav league in 1991. Dinamo are, to date, the only Croatian club to win a European trophy, having won the 1966–67 Inter-Cities Fairs Cup by defeating Leeds United in the final. They also finished runners-up in the same competition in 1963 when they lost to Valencia.
Until the early 1990s, its foundation year was considered to be 1945 but amid the political turmoil during the breakup of Yugoslavia the club began claiming direct lineage to pre-WWII clubs Gradanski Zagreb and HASK. In order to reflect this, in June 1991, it was renamed HASK Gradanski, which lasted until February 1993 when it was renamed Croatia Zagreb. They won five league titles and participated in the 1998–99 and 1999–2000 UEFA Champions League group stages carrying that name, before reverting to the more widely recognized "Dinamo Zagreb" on 14 February 2000. Although the subject of the club's name was dropped for a while, in 2011, club management increasingly began claiming again that Dinamo is the direct descendant of Gradanski (which had originally been founded in 1911 and disbanded in 1945) and in April that year decided to prepend the adjective "Gradanski" to the club's official name, turning it into the present-day GNK Dinamo (Gradanski nogometni klub Dinamo or Dinamo Citizens' Football Club).
The team's traditional colour is royal blue, which has been replaced for European matches in recent times with the darker navy blue. The club's biggest rivals are Hajduk Split, and matches between the two teams are referred to as "Eternal Derby".
