The 22nd edition of the quadrennial tournament, which began way back in 1930, is also the first to be held in an Arab country. The State of Qatar is the smallest country in size (11,600 km2) and population (2.7 million) ever to host.
This format will be changed for the World Cup 2026 when the tournament will be expanded to 48 teams as the USA, Mexico and Canada co-host.
