SK Telecom T1 League of Legends team at the World Championship 2013

SKT 2 won their first League of Legends World Championship.[5] In 2014, SK Telecom T1 K followed their success through in the OGN winter season, winning the tournament without dropping a single game. They would then go on to win All-Star Paris 2014.[6] However, their Winter season success did not follow through and after the Spring and Summer seasons, SKT T1 K failed to qualify for the 2014 World Championship. In the following offseason, Riot Games changed the team regulations so that each organizations may only have one team participating in each league. This led to the merger of SKT T1 K and SKT T1 S, and the subsequent departures of Impact and Piglet for the NA LCS.[7] The new team would compete under the name SKT T1.

At the 2015 World Championship, SKT won the title while losing only one game in the finals for a record of 15–1 over the course of the tournament.[8]

SKT team started off the 2016 Season by winning the LCK Spring Split.[9] With this victory, SKT was guaranteed a spot in the 2016 Mid-Season Invitational.[10] At that point in time, MSI was the only major international tournament they had yet to win. They were heavily favored coming into the tournament, but were initially unable to perform up to their usual standards, unexpectedly losing several games in the group stage.[11] However, they managed to turn things around during the elimination round and eventually clinched the title by sweeping the North American team, Counter Logic Gaming, in the finals.[12] SKT placed third in the 2016 LCK Summer Split, but still qualified for the 2016 World Championship through circuit points. The team swept through the group stage and advanced towards the playoff round. In the semifinals they defeated the ROX Tigers in a close 3–2 series.[13] In the finals they defeated Samsung Galaxy in another close 3–2 series, winning their third world championship title.[14][15] Faker was voted as the Most Valuable Player of the tournament.[16]

SKT won the 2017 LCK Spring Split, clean sweeping KT Rolster 3–0 in the finals. This win qualified them for the 2017 Mid-Season Invitational.[17] At the 2017 Mid-Season Invitational, SKT topped the group stage with a 8–2 record. SKT then swept Flash Wolves 3–0 in the semifinals and defeated G2 Esports 3–1 in the finals, becoming the first team to win the Mid-Season Invitational back-to-back.[18] At the 2017 World Championship, SKT were considered to be strong favourites to lift the cup for a third consecutive time despite not winning the LCK Summer Split. After a 5–1 group stage, SKT narrowly defeated Misfits and Royal Never Give Up in the quarterfinals and semifinals, respectively, before facing Samsung Galaxy in a repeat of the previous year's final. Despite being favourites going into the game, Samsung Galaxy swept SKT 3–0, ending their domination at the World Championship.[19]

SKT finished fourth in the 2018 Korea Regional Finals,[20] failing to qualify for the 2018 World Championship.[21]

In April 2019, SKT won the LCK Spring Split.[22] As champions, SKT represented the LCK at the 2019 Mid-Season Invitational. They finished the group stage in second place but lost 3–2 to G2 Esports in the semifinals.[23] In the LCK Summer Split, SKT repeated the success and defended their title.[24] SKT qualified as the LCK's first seed for the 2019 League of Legends World Championship, where they were once again defeated by G2 Esports in a semifinals series, losing 3–1.[25][26][27]

In October 2019, SKT rebranded as T1 after partnering with Comcast Spectacor.[28] In February 2020, Faker had re-signed with the team for three years, in which his contract would last until 2022. He also became a part owner of T1 Entertainment and Sports.[29][30] In April of the same year, T1 defeated Gen.G and won their ninth LCK title.[31]

At the 2021 League of Legends World Championship, T1 was eliminated in the semifinals by DWG KIA, losing 3–2 in a best-of-five series.[32]

During the 2022 LCK Spring Split, T1 went undefeated in the regular season with an 18–0 record, becoming the first team to achieve this record since the league's inception.[33] In the playoffs, T1 won its tenth LCK title, defeating Gen.G 3–1 in the finals.[34] On the international stage, T1 finished as the runners-up of the 2022 Mid-Season Invitational, losing in the final to Royal Never Give Up.[35] T1 qualified for the 2022 League of Legends World Championship as the LCK's second seed after accumulating the most championship points during the 2022 season.[36] The team made it all the way to the grand finals, where they lost 3–2 to DRX, finishing runners-up.[37]

In the 2023 LCK Spring Split, T1 repeated their strong form during the regular season to qualify for the playoffs as the first seed, posting a 17–1 record as all five members of the roster were chosen for the All-LCK First Team, a first in LCK history.[38][39] There, the team won every series to advance to the finals, notably qualifying for the 2023 Mid-Season Invitational after defeating Gen.G in the upper bracket semifinals.[40] Albeit, T1 ended up losing the Spring Split title against the same opposition in a rematch of the 2022 LCK Summer 2022 finals, as Gen.G won the match 3–1.[41]
