The years from 1928 to 1930 witnessed a bitter struggle for the control of the German National People's Party (DNVP), the bastion of German conservatism in the Weimar Republic. One of the principal protagonists in this conflict was Count Kuno von Westarp, chairman of the DNVP from 1926 to 1928 and of the DNVP delegation to the Reichstag from 1924 to 1929. Westarp struggle with great determination to preserve the unity of the party in the face of a concerted effort from the radical Pan-German nationalists around the newly elected party chairman, film and press magnate Alfred Hugenberg. But Westarp's efforts on behalf of party unity ultimately failed as the moderates who stood on the DNVP's left wing abandoned the party in two secessions, the first in December 1929 and the second in July 1930. In the second of these Westarp himself left the party. In the meantime the DNVP had been transformed from a conservative Sammelpartei into an instrument of the radical right.
