The Czech Women's First League (Czech: I. liga žen) is the top level women's football league of the Czech Republic. The league is dominated by teams of Prague. Slavia Prague won the last championships, Sparta Prague was runner-up. The winning team and runners-up of the league qualifies for the UEFA Women's Champions League.
The I. liga started as a competition for 12 teams, each playing all other teams twice.[1]
In 2002, the number of teams was reduced to ten and after the regular season was followed with a playoff with eight best teams.[1] In 2006, the system was abandoned and a league of 12 teams was re-instated.
Since 2009-10, only eight teams participated in the league and after the regular season, a playoff system was held. In those two playoff groups, place 1 to 4 for the championship and the relegation group for teams placed between 5th and 8th positions. In 2010–11 nine teams played again only a double-round robin.
