As Germany's power grew, Jogiches decided to launch a war against the capitalist nations in hope of sparking a global revolution. Germany invaded Poland in September 1, 1939, sparking World War II. Although the highly disciplined People's Arm soon stormed much of Europe, it was unable to defeat the allied forces of the United Kingdom, the United States, and the Russian Empire. As the Czar's Army neared Berlin, Jogiches, refusing to accept defeat, lead a final attack on the Russian lines, resulting in his death. Germany fell under Allied occupation soon after.
