The Nazis solidified support amongst nationalists and conservatives by presenting themselves as allied with President Paul von Hindenburg who was considered a war hero of World War I in Germany. The Nazis sought to gain support of workers by declaring May Day, a day celebrated by organized labour, to be a paid holiday and held celebrations on 1 May 1933 to honour German workers. The Nazis stressed that Germany must honour its workers. Hitler often praised the virtues of labor, declaring in the "Völkischer Beobachter" that "I only acknowledge one nobility—that of labour."
