What is the name of the Pokémon League conference Ash wins in the Pokémon TV series’ Alola region?

Ash wins the Manalo Conference in the Pokémon TV series’ Alola region.

The Manalo Conference is the first Pokémon League competition held in Alola in the anime. Ash reaches the final and defeats Gladion, winning the championship and becoming the first Alola Pokémon League winner.

The final battle takes place at Manalo Stadium and concludes with Ash’s Lycanroc defeating Gladion’s Lycanroc. The result is especially notable because it gives Ash his first official regional Pokémon League championship after many earlier attempts.

The name can be confused with Alola itself, which is the region, or with the Pokémon School, where Ash studies during much of the Sun & Moon storyline. “Manalo Conference” is the specific name of the tournament, not the name of the region or school.
