Mid-Season Invitational is an annual League of Legends tournament, happening between the Spring and Summer splits of all regions. The Spring Split champions of each LoL Region compete for the MSI trophy and an extra team slot for their region at LoL Worlds.
The first Mid-Season Invitational was held in 2015 in Tallahassee, Florida. The event featured the champions of the five main LoL regions and one extra team from the International Wildcard event. Edward Gaming were crowned the first ever Mid-Season Invitational Champions. Since then, four different teams earned the MSI trophy, with SKT T1 as the only team holding a back-to-back crown.
In 2021, the Mid-Season Invitational features 12 teams, and the winners of every region in the LoL Esports ecosystem.

Mid-Season Invitational History
The MSI History started in 2015, with the tournament evolving with each consecutive iteration.

Initially the LoL esports system consisted of major and minor regions with the main regions automatically participating in the MSI Group Stage, while the minor regions had to play through a Play-Ins event. Starting in 2021, all regions are on equal grounds and they are seeded based on their regions past performance in international League of Legends events.
