The Pokemon League is basically the point of all the Pokemon adventure games. It has the Elite Four (and your rival) which are the most skilled trainers in the Pokemon world and if you beat them, you can call yourself the Pokemon Master. You must face the Elite Four (and your rival) all in a row without letting your Pokemon faint, if they do, you must start over again.
That depends on what league you are talking about.
