LOL - LEC Spring

Riot Games launched League of Legends in October 2009 and attracted attention from the competitive gaming community. The first two seasons of competitive play consisted of a series of tournaments mostly organised by third parties, such as Intel Extreme Masters in Europe, capped by a world championship tournament hosted by Riot Games.^[]

Riot Games announced the formation of the LCS on 6 August 2012, creating a fully professional league run by the company with a regular schedule and guaranteed salaries for players, featuring eight teams. Since the LCS was only launched in the third year of professional play, it was dubbed "Season 3". The top three finishers in the Riot Games European regional championships held in August 2012 automatically qualified, with the remaining five teams being decided in qualifier tournaments held in January 2013. Each LCS season is divided into two splits for spring and summer; the first games of the first spring split took place on 7 February 2013 in North America and on 9 February 2013 in Europe.

Season 3 of the LCS finished with the top three finishers Fnatic, Lemondogs, and Gambit Gaming. The top three teams advanced to the Season 3 World Championships.

Riot Games changed naming conventions in 2014, calling the season the "2014 Season" instead of "Season 4". The League of Legends Challenger Series was created as a second tier of competition for promotion and relegation.

At the end of the 2014 season, an expansion tournament was held in Europe that added two teams in region, giving the LCS a total of 10 teams for the start of the 2015 Season. Additionally, Riot introduced the concept of "Championship points", which teams would earn based on performance across both splits and playoffs in order to qualify for the League of Legends World Championship.

A new sale of sponsorship rule was instated for the 2015 season. As a result, several teams were forced to rebrand and leave their respective parent organisations.

The 2015 Summer European LCS Finals were played at Hovet Arena, Stockholm. The series ended with Fnatic winning 3–2 over Origen and peaked at close to 1 million concurrent viewers on Twitch, YouTube, and Azubu – the highest number of viewers for any LCS match to date.

The 2016 Spring European LCS finals were held at Rotterdam Ahoy in Rotterdam, with G2 winning 3–1 against Origen, making it their first LCS title. The 2016 Spring European LCS split was the first time G2 played in the professional LCS after having been promoted due to winning the European Challenger Series and European Promotion Tournament in summer 2016.

The 2016 Summer European LCS finals were played at the Tauron Arena in Kraków, Poland. G2 won 3–1 against Splyce and secured their second LCS title. Splyce would later win the 2016 Summer European Gauntlet and qualify for Worlds as the third-seeded European team.

The 2017 Spring European LCS finals were held at the Barclaycard Arena in Hamburg, Germany, where G2 won 3–1 against Unicorns of Love, securing their third LCS title and qualifying for the Mid-Season Invitational (MSI), an annually-held international League of Legends competition. G2 placed second at the MSI 2017, losing 1–3 to SKT T1, the Korean representatives, in the finals. The Summer Split LCS finals took place in Paris at the AccorHotel Arena, where G2 Esports won 3–0 against Misfits Gaming.

In 2019 the league rebranded from the "Europe League Championship Series" (EU LCS) to the "League of Legends European Championship" (LEC) and began franchising. Following the example of North America's LCS, which franchised a year prior, the LEC selected ten permanent franchise partners, replacing the previous promotion and relegation format. The EU LCS' secondary league, the EU Challenger Series (EUCS), was consequently discontinued and replaced with an independent tournament named European Masters, which features the top teams from Europe's many regional leagues.

In 2020, the league announced via their public Twitter account a partnership with a proposed Saudi Arabian city, Neom. Following major community backlash over the human rights abuses in the country, including criminalization of LGBT people, the partnership was called off the next day. Another two days later, the league's Director of Esports EMEA, Alberto Guerrero, put out a statement apologizing to the community for the partnership decision, with emphasis on apologizing to 'women, LGBTQIA+ individuals, and League of Legends players in the Middle East'.

Since 2023, Turkey, CIS and MENA have merged with Europe region to become a EMEA (Europe, the Middle East and Africa) region. The "League of Legends European Championship" become the "League of Legends EMEA Championship", meaning teams from Turkey and CIS's leagues (TCL, LCL) will no longer get direct slots for the Mid-Season Invitational and the World Championship. TCL will be a qualification of Tier-2 league EMEA Masters.
