Riot began to work hard in the field of e-sports professional competitions in 2011. After two years of exploration and exploration, 2013 can be said to be the highest bright moment of Riot's exploration of professional leagues, because in this year, they held 7 international competitions around the world.
Let’s take a look at what international competitions Riot held in 2013.
IEM Season 7 Katowice Station (January 2013)
Champion - Gambit Gaming!

Intel Extreme Master, this event lasts for a long time and spans multiple cities. This is one of the most popular events in the history of League of Legends , full of incredible storylines.
At this time, the power of South Korea is truly fearful and respectable. It is a complete and powerful competition area. The Korean team is also a very popular event in this event.
Two famous Azubu teams, Frost and Blaze, both come from South Korea. The two teams remained unbeaten in the group stage, and this match seemed like a relatively easy victory for the Korean team. Gambit scored 1-2 in the group stage and advanced to the next stage through the final game rules.
Fnatic also advanced with a score of 2-1. FNC in the last game of the group stage against SKG, xPeke used Kassadin to steal the house, which is also one of the most famous clips in League of Legends history.
Fnatic then lost to Azubu Blaze with a small score of 1-2 in the semifinals, as most people expected. After
Gambit Gaming successfully defeated the popular team Azubu Frost 2-0 in the semi-finals. In the finals, Gambit Gaming also shocked the world by defeating another popular player Azubu Blaze 2-0.
Gambit Gaming remained unbeaten against the Korean team after the group match. This is also the origin of their being called Korean killers.
Sao Paulo IEM Global Challenge (January-February, 2013)
Champion - Incredible Miracle!!

That game was a very strange event, I must admit that I don’t remember it very clearly
The weirdness of it is that there are not many top teams participating at all. Most of them are low-level teams and some Brazilian local teams.
Some players from Europe also participated in the competition, and they all became celebrities on the field, Overpow, Celaver, Xaxus, Tabzz, Creaton, Kubon, Czaru. You can see a lot of Polish players, and in fact, there are two Polish teams participating in Anexis and MYM.
Unfortunately, no Brazilian team can qualify from the group stage. The promotions were 3 European teams and 1 Korean team.
Here, Incredible Miracle from South Korea swept the knockout stage without any loss and won the game. Interestingly, none of the players on this IM team has become the most famous player today. The only thing that left a little impression on me was Lilac, but even so, he was a pretty inconspicuous player.
IEM Season 7 World Championship (March 2013)
Champion——CJ Entus Blaze!

IEM Season 7 World Championship was held in Hannover, Germany. Many top teams from Europe and South Korea participated in the competition, and even PaiN from Brazil came.
This is another super event after Gambit Gaming defeated South Korea in the last big event. Two Azubu teams also attended again, although they are now known as CJ Entus Blaze and Frost.
Gambit Gaming remained unbeaten during this group stage, advancing with Millenium and CJ Entus Blaze of Group A.
in Group B, SK Telecom T1 (the mid laner was Reapered-Faker has not yet appeared), CJ Entus Frost and Anexis Esports advanced.
Shockingly, the old CLG.EU team (now called EG) did not advance from the group, nor did South Korea's Incredible Miracle.
In the knockout stage, the Korean team is really back this time.CJ Entus Frost avenged and beat Gambit Gaming 2-1. Before that, they also eliminated Millenium in the quarterfinals.
CJ Entus Blaze eliminated Poland's Anexis 2-0, and also swept Realpered and SKT in the semi-finals. In the final of
, two CJ Entus teams faced off for the championship. In the intense BO5 series, CJ Entus Blaze beat their sister team and won the championship.
This is one of my favorite games at the time and it is an absolute fun to watch the game.
013 Asian Indoor Martial Arts Games (June-July 2013)
Champion - KT Rolster Bullets!

Another pretty unknown event, obviously only Asian teams participated. Each team has one region to participate. KT Rolster in Korea, WE of LPL, Taipei Snipers of LMS and Saigon Jokers of SEA.
South Korea and China swept the game and met in the final, KT:B won by a slight advantage of 2-1 and successfully promoted the competition area culture, that is, South Korea is stronger than China.
Interestingly: Score played ADC in this game, and he was one of the few players to win the game in multiple positions. Other famous players in this team have. Ssumday, Ryu and Insec. Support Mafa later became a successful coach.
013League of Legends Global Finals (September-October 2013)
Champion - SK Telecom T1!

Due to the rapid growth of LCS and other competition areas, we have not participated in any international competitions for a long time. In addition to the Asian Games, this is the first truly international event in the past six months.
S3 World Championship is obviously a very memorable and beloved competition. This is the first time we have really seen Faker and Uzi perform on the international stage.
This is indeed the beginning of the era of Faker's rule, and in this game, a large number of mid-lane assassins further demonstrated this. This is indeed a paradise for mid laners.
In this form, some teams skipped the group stage. NA's C9, South Korea's Najin Black Sword, Royal Family and LMS's Gamania Bears (Orange Bear).
In Group A, SKT T lost only one game and advanced with China's OMG. The mid laner is a famous player in the stateless state. European LemonDogs and NA's TSM did not advance. The score for LD is 3-5 and the score for TSM is 2-6. The competition in the
B group is even more intense, with Europe's Fnatic and Gambit both advanced. Shockingly, South Korea's Samsung Ozone didn't advance -- mainly due to Dade's poor performance. This is also why Thorin and Monte Cristo invented the famous Dade Award. NA's Vulcun didn't advance, either, although it looked pretty good in some games.
In the quarterfinals, FNC beat C9 2-1, with NA fans frustrated that C9 did not ban xPeke's Kassadin directly. Royal wins the match against OMG, Najin beats Gambit 2-1, and SKT sweeps the Orange Bears.

In the semi-finals BO5, Uzi and the royal family defeated Fnatic. Another semifinal was played between Najin Black Sword and SKT T, with a 3-2 score that could result in any results. This is almost a true final. This is an interesting idea, players like Pray, Expession and Nagne can be said to have become world champions in one game. However, Faker and SKT won.
In the final, SKT swept the royal family 3-0 with its strong dominance. The first part of the SKT Faker dynasty has officially begun!
IEM Season 8 Singapore Station (November 2013)

Champion - Invictus Gaming!
This is another event exclusive to Asia, I must admit that I don’t remember it very clearly. It is divided into professional competitions and amateur competitions.
IG won the championship by defeating CJ Entus Frost in the final. South Korea and China once again lead the teams in other Asian divisions.
Interestingly: This is the first large-scale event of the DFM team in LJL Division. They only participated in amateur events and did not pass the first stage.
IEM Season 8 Cologne Amateur Competition (November 2013)
Champion - Gambit Gaming

Gambit Gaming won another match in Cologne. This time, teams from the north and Europe participated, as well as some teams from small competition areas.
Wild card teams from TR and CIS were eliminated in the first round, and in the following game, NA and EU faced off in two semi-finals.
Gambit beat C9, while FNC beat CLG.
In the final, Gambit beat FNC 2-0 and ended the entire game without losing a inning.
013 Atlantic Battle (December 2013)
Champion - North American Division

This is a very unique event, Riot was held to strengthen the confrontation between NA and EU. Many teams from NA and EU participated in this game to demonstrate their strength in the competition.
This game is quite controversial because although EU won more games than North America, it still lost in points.
EU team won 6-4, while NA team won 4-6.
The reason is that in terms of points, high seed teams are the most important.
Sadly, LemonDogs sold all their starters before the game, and they were counted as second seeds as they reached the final in the 2013 Summer Tournament. However, since the team has 5 new players (and not very good players), they lost to TSM 0-2.
In other matches Alliance (old CLG.EU) beat Dignitas, Alternate beat CLG, Gambit beat XDG, and C9 beat Fnatic.
Overall, NA won the game with the rules in place, but it was quite a bad thing at the time. An interesting but chaotic event, I'm just a normal game, and the team can play for their reputation rather than the prestige of the division, which can also avoid these weird rules.
—————
OK. The above are various international events held by Riot directly participated or instructed by the 2013. In that year, League of Legends Professional League blossomed everywhere, but perhaps it was also realizing that such instructiveness would bring chaos in professional competitions. So in the following years, Riot began to slowly withdraw some of the rights to host the event. Until now, Riot has completely controlled the competition independently.
