Dinamo 1948, commonly known as Dinamo București () or simply Dinamo, is a Romanian professional football club based in Bucharest, which competes in the Liga II. Founded in 1948, it has spent almost its entire history in the Liga I, the top tier of the Romanian league system. Domestically, Dinamo București is one of the two most successful teams in the country, having won 18 Liga I titles, 13 Cupa României, two Supercupa României, and one Cupa Ligii. In the 1983–84 season, it became the first club in Romania to reach the semi-finals of the European Cup. Dinamo București's traditional home colours are white and red, while the current crest is a modified version of the one adopted in the 1998. Their home venue is the namesake Stadionul Dinamo, although significant matches have also been played at Arena Națională. Their bitter rivals are neighbouring FC Steaua București, with the matches between the two being commonly referred to as "the Eternal Derby". History Dinamo București was founded on 14 May 1948, when Unirea Tricolor MAI, newly entered in January 1948 under the umbrella of the Communist regime's Internal Affairs Ministry, merged with Ciocanul București. The people who contributed at the foundation of the club were the Minister of Internal Affairs, Teohari Georgescu and the Jewish brothers Alexandru and Turi Vogl. The sporting club represented the above-mentioned institution. The "Dinamo" name was used for the first time on 1 May 1948. Nevertheless, the real debut of Dinamo was in the 1947–48 Divizia A edition, finishing eighth. The squad included Ambru, Angelo Niculescu, Teodorescu, Șiclovan, Bartha, and Sârbu. In 1955, Dinamo achieved its inaugural league championship. With Angelo Niculescu as head coach, Dinamo had a strong offensive power, with an attack formed by Ene I, Neagu and Suru. The defense, with players like Băcuț I, Băcuț II, Szökő, Călinoiu, was the best in the championship, with only 19 goals conceded. In the fall of 1956, the team achieved Romania's inaugural presence in European competition in the European Champion Clubs' Cup, created in 1955. On 26 August 1956, with 32,000 spectators, Dinamo defeated Galatasaray, 3–1. In the second leg, Dinamo would lose in Istanbul 1–2. Other teams Dinamo would compete in Europe, were Real Madrid (a team with Di Stefano and Gento – the game played in Bucharest took place at 23 August Stadium, and established a new record for this arena: 100,000 spectators),
