The Nebraska chapter of the National German-American Alliance (NGAA) was founded and led by Valentin J. Peter, the publisher and editor of the German language "Omaha Tribune" in 1907. By the 1920s the organization was working closely with breweries throughout the city to challenge the complete political and social assimilation of German immigrants in Nebraska. During the same period Peter was buying other German-language newspapers across the U.S. The NGAA folded in the late 1920s; Peter's business, the Interstate Publishing Company, still operates in Omaha today.
