History of the LCK
Known in 2012 as the League of Legends Champions, the LCK started out as the league to watch for years to come. From 2012-2014 there were even three splits per season in this tournament, 16 teams took part.
For the 2015 season, the format has changed significantly: The winter split was removed, and the number of teams was reduced to 10. The LCK is also using a franchising system since 2021, which has eliminated the relegation tournament and the Challengers Korea League since then.
The LCK won all world championship titles between 2013 and 2017. It was only in 2018 that the LPL (China) managed to secure the first Worlds title for the region with Invictus Gaming. This means that the LCK is still the region in LoL Esports.
