In League of Legends are teams from so many regions around the world that can qualify to World Championship. Teams can be champion of their region twice a year, because there are two splits. Spring split and Summer split.
In Europe, we have LEC (League European Championship) where 10 teams tries to be the European Champion. The latest champion is team called Mad Lions, which have won the LEC in both splits this year.
LCS (League Championship Series) takes place in North America. There are also 10 teams, like in Europe. The last LCS champions were Cloud9, but they won just the Summer split. The Spring split was won by Team SoloMid.
LCK (League Championship Kore) is being played in Korea and there are 10 teams fighting for qualifying to the World Championship. The first LCK match was played in 2012. From LCK are the most powerful teams, like DWG Kia, T1 or Gen.G. Last years LCK was won by DWG KIA, which have won the both splits.
LPL (League of Legends Pro League) takes place in China. The first season of LPL was in 2013. LPL is different from other regions, because there are 17 teams trying to win the championship.
