The municipality was created in 1971, when the City of Vetlanda (instituted in 1920) was amalgamated with the surrounding rural municipalities to form a unitary municipality. In 1863, when the first local government acts in Sweden came into force, there were more than 20 enities within the area of the present municipality.
