Albert I, Prince of Monaco soon suspended by the Prince when World War I broke out. Also in 1911, Prince Albert created the Monte Carlo Rally, an automobile race designed to draw tourists to Monaco and the Casino. Despite his military service, or perhaps because of it, the Prince became a pacifist, establishing the International Institute of Peace in Monaco as a place to develop a peaceful settlement for conflict through arbitration. In the tension-filled times leading up to World War I, Prince Albert made numerous attempts to dissuade Germany's Kaiser Wilhelm II from war. When war came, Prince Albert could not avoid becoming involved.
