Which organization won the first Dota 2 International championship in 2011?

Natus Vincere won the first Dota 2 International championship in 2011.

The Ukrainian organization, commonly abbreviated as Na’Vi, defeated EHOME 3–1 in the grand final at Gamescom in Cologne, Germany. The event was the first world championship organized by Valve for Dota 2, which had entered its public beta shortly before the tournament.

Na’Vi’s lineup included legendary players such as Danil “Dendi” Ishutin and Clement “Puppey” Ivanov. Their victory established the organization as one of the defining early names in professional Dota 2. The tournament’s prize pool was notable for its time because Valve funded it with a then-record esports purse of $1.6 million.

This result is distinct from Na’Vi’s later appearance in the 2012 final and from the team’s 2013 title run, which was won by Alliance. The answer refers specifically to the inaugural International championship.
