What is the IESF?

The International Esports Federation, founded in 2008, is esports' national-team body — 140+ member federations running the annual World Esports Championships in a country-versus-country format that mirrors traditional sport.[1] [2]

What are its limits?

Real ones, and worth stating plainly: the IESF can only run competition in titles whose publishers permit it. The commercial centre of esports — Riot's and Valve's ecosystems — sits entirely outside its authority, which is why esports' "world championships" are usually publisher events rather than federation ones.[2] [3]
