World War I began in 1912 with a rebellion in Arkansas and Louisiana. When the Central Powers granted Louisiana diplomatic recognition, most Entente nations declared war on them. In North America it was thus: Louisiana Rebels, the USA, Deseret, California and Sonora and Yucatan against BC, Canada , Russia, the CSA, Texas, and Mexico as the Central Powers and Entente respectively. In South America it was Brazil, Argentina, and Columbia against Venezuela, Chile, Peru, and Ecuador. In Europe and the Middle East it was Germany, Austria-Hungary, Ottoman, Bulgaria and Italy against Britain, France, Russia, Serbia, Greece, and Montenegro. In Asia it was Russia versus China.
