Valentin J. Peter, editor of the German-language "Omaha Tribune", was chiefly responsible for the formation and leadership of the National German-American Alliance. This coalition was influential in representing and leading the German-American electorate across the United States between 1912 and 1940. During the early years of World War I, Peter was supportive of Germany and urged German-Americans to be so, too. He changed his position before the US entered the war on the side of Great Britain and France, and supported the Allies.
