Pokémon League is a center where all Pokémon trainers come to battle the leaders of all trainers. To enter you have to collect all of the badges. Also, you are only allowed to use six Pokemon at a time, both in the games and the anime. However, unlike in the games, in the anime a lot of Trainers participate and battle each other, whereas in the games only the player is battling the Elite Four.
