In 1933, FV joined the Gauliga Mittelrhein, one of sixteen top flight divisions established with the re-organization of German football in Nazi Germany that year. The club was immediately relegated, and in 1934 was joined by Turnverein 1864 Neuendorf, Arbeitersportverein Neuendorf and DJK Neuendorf, to create Turn- und Spielvereinigung Neuendorf. Both ASV and DJK were forced into the merger through the policies of the Nazi regime which regarded worker's and church-sponsored clubs as politically undesirable. TuS Neuendorf returned to first division play in 1935 and was in and out of the Gauliga over the next several seasons.
