of football in the entire country, while Zagreb was turned into its major regional hub and administrative branch. In this period Croatian clubs competed within the Yugoslav league system and Croatian players were eligible for the Yugoslavia national football team. In the following decades Dinamo Zagreb and Hajduk Split became two of the Yugoslav Big Four (along with Belgrade-based Partizan and Red Star), a quartet of clubs which significantly dominated football in communist Yugoslavia. Dinamo and Hajduk won a combined total of 11 Yugoslav First League titles and 16 Yugoslav Cup. In addition, Croatian club Rijeka won 2 Yugoslav Cup titles. Dinamo Zagreb also won the 1966–67 Inter-Cities Fairs Cup, which made them the first Yugoslav side to win a continental competition, and were the only Yugoslav club with European silverware until Red Star's 1990–91 European Cup win 24 years later. Modern era (1990–present) When the breakup of Yugoslavia began to unfold in the early 1990s, the political situation was reflected on football pitches. On 13 May 1990 an infamous riot occurred at Maksimir in Zagreb and interrupted the Dinamo Zagreb – Red Star league fixture. On 3 June 1990 the pre-scheduled Yugoslavia–Netherlands friendly was held at the same stadium, and some 20,000 Croatian fans booed the Yugoslav national anthem and cheered for the Dutch team instead. On 26 September 1990 Hajduk Split fans staged a violent pitch invasion at Poljud during a league fixture against Partizan. On 17 October 1990 the first match of the newly established Croatia national football team was held, a friendly against the United States, and following the end of the 1990–91 season Croatian clubs decided to abandon Yugoslav competitions. After Croatia had officially declared independence on 8 October 1991, the Croatian Football Federation sought international recognition, and was finally re-admitted to FIFA on 3 July 1992 and to UEFA on 17 June 1993. In February 1992 the inaugural season of the Croatian top league Prva HNL kicked off, and in March 1992 the first edition of the Croatian Cup was launched. In late 2010, the Federation held an election for its President, with Vlatko Marković opposed by Igor Štimac. Marković won by a single vote, and the assembly was marred with controversies. Štimac later appealed, calling for another meeting of the Federation. His supporters organized a new assembly and elected him the new President despite the opposing faction's boycott, leading to an impasse. In
