In the late 19th century, French imperialist politicians invoked the "Péril jaune" (Yellow Peril) in their negative comparisons of France's low birth-rate and the high birth-rates of Asian countries. From that racist claim arose an artificial, cultural fear among the French population that immigrant-worker Asians soon would "flood" France, which could be successfully countered only by increased fecundity of French women. Then, France would possess enough soldiers to thwart the eventual flood of immigrants from Asia. From that racialist perspective, the French press sided with Imperial Russia during the Russo-Japanese War (1904–1905), by representing the Russians as heroes defending the white race against the Japanese Yellow Peril.
