In some countries badminton isn't a hobby — it's a national obsession. This guide explains where badminton is the national or most-loved sport: Indonesia (where it's woven into the national identity), Malaysia, China, and its huge followings across Asia and northern Europe. It covers why the sport took such deep root in these places, how it became a source of national pride, and the players and team cups that turned badminton into more than a game.
