Veikkausliiga is the premier division of Finnish football, comprising the top 14 clubs of the country (season 2006 was played exceptionally with 13 teams because of the AC Allianssi bankruptcy). Its main sponsor is the Finnish national betting agency Veikkaus, hence the league's name. Veikkausliiga was founded in 1990; before that the top division was called Mestaruussarja (championship series) since 1930. Between 1908 and 1930 the championship was decided in a cup competition.
