The team narrowly missed qualifying for the regional top-flight Gauliga Nordhessen (I) in 1935, but eventually won promotion to the Gauliga Kurhessen (I) in 1941. They struggled through the next two campaigns earning only lower table finishes there.

The club abandoned it place in Gauliga play in March 1944 to take part in lower-level competition.
