The district was set up in 1994 by joining the old districts of Eisenach and Bad Salzungen, and a few municipalities from the district Bad Langensalza. The city of Eisenach left the district in 1998 and became a district-free city.
The coat of arms combines the symbols of the historic states which existed on the territory.
