In 1933, Hitler was under the influence of the Templar Order, obtaining an Apple of Eden from Templar industrialist Henry Ford to utilize as a catalyst for initiating World War II. Alongside fellow Templar puppets, Roosevelt and Stalin, Hitler brought on the turmoil and fear necessary for Abstergo Industries to push forward its industrial development and take control of the working population.
However, by 1943, the Templars' influence over Hitler and the other world leaders began to dwindle, and the Order found it hard to ensure their control over Nazi Germany. As such, the Templars began colluding with the Assassin Boris Pash to create a machine called Die Glocke, which would be capable of creating a wormhole to traverse time and allow the Templars and Assassins to kill Hitler before his rise to power.
After Obbergrupenführer Gero Kramer's experiments in Vemork were sabotaged by Nikola Tesla, Pash used his research alongside Templar John von Neumann to conduct a similar experiment in Philadelphia on 28 October 1943, called Project Rainbow. After the Assassin Eddie Gorm sabotaged Pash's plans by killing Tesla, John von Neumann was directed to the Manhattan Project to help the Americans build nuclear weapons to turn the tide against the Nazis.
By the end of the war, with the Nazis on the verge of defeat, the Templars were able to exert their influence over Hitler once more. On 30 April 1945, Hitler executed his body double inside the Führerbunker and planned to meet an agent referred to as C. with the Apple of Eden at a rendezvous point. However, upon leaving the bunker, Hitler was killed by Assassins.
- Historically, Hitler won the Iron Cross twice during World War I for bravery. The Iron Cross resembles, in this instance, the mark of Cain, and the Teutonic cross.
- Hitler planned to revive the Knights Teutonic, as he greatly admired their work during the Crusades.
