The Liga I (; First League), also spelled as Liga 1, is a Romanian professional league for men's association football clubs. Currently sponsored by betting company Superbet, it is officially known as the SuperLiga. It is the country's top football competition, being contested by 16 clubs which take part in a promotion and relegation system with the Liga II. The teams play 30 matches each in the regular season, before entering the championship play-offs or the relegation play-outs according to their position in the regular table. The Liga I was established in 1909 and commenced play for the 1909–10 campaign, being currently on the 29th place in UEFA's league coefficient ranking list. It is administered by the Liga Profesionistă de Fotbal, also known by the acronym LPF. Before the 2006–07 season, the competition was known as Divizia A, but the name had to be changed following the finding that someone else had registered that trademark. The best performer to date is FCSB with 26 titles, followed by longtime cross-town rival Dinamo București with 18 trophies. Furthermore, of the remaining 21 clubs which came victorious in the competition, eight have won it on at least three occasions—CFR Cluj (eight trophies), Venus București (seven), Chinezul Timișoara and UTA Arad (six each), Ripensia Timișoara, Universitatea Craiova and Petrolul Ploiești (four each), and Rapid București (three). History Early championships (1909–1921) The first official national football tournament was organized in 1909 by the recently founded Romanian Football Federation, then called the Association of Athletic Societies in Romania (). The final matches of the first Romanian Football Championship were held between December 1909 and January 1910 in Bucharest. The three pioneer clubs were Olympia and Colentina from Bucharest and United from Ploiești. Each team played a fixture against the other two clubs, totalizing a number of three matches disputed, with Olympia București being crowned as champions of the first Romanian Football Championship. In the following years, the tournament was structured into regional groups with the winners of each group participating in a playoff with the eventual winners being declared champions. From 1909 until 1921, the championship was organized as a cup with the winner being crowned as Champions of Romania, except for between 1916 and 1919, when the competition was suspended due to World War I. The champions of this period were Olympia and Colentina, each with two titles, and United, Prahova, Venus, Unirea Tricolor București
