During the late 1920s and early 1930s, Renault was surpassed by Citroën as the largest car manufacturer in France. Citroën models at the time were more innovative and popular than Renault's. However, by mid-1930s the French manufacturers were hit by the Great Depression. Renault could initially offset losses through its tractor, railroad and weaponry businesses, while Citroën filed for bankruptcy, and was later acquired by Michelin. Renault became again the largest car manufacturer, a position it would keep until the 1980s.
