Final answer:
Adolf Hitler was appointed as chancellor of Germany in January 1933, and he quickly consolidated power, eventually becoming the undisputed head of state as Führer und Reichskanzler in 1934. This laid the groundwork for World War II.
Step-by-step explanation:
Adolf Hitler was appointed as chancellor of Germany in January 1933. This event set the stage for a drastic change in German politics and society. Upon his appointment, Hitler maneuvered to consolidate power swiftly, leveraging the passage of the Enabling Act in March 1933, which granted him the authority to legislate independently of the German parliament. Hitler's aggressive domestic and foreign policies soon transformed Germany into a totalitarian state and precipitated World War II.
The Enabling Act allowed Hitler to rule without constitutional limitations, and following the death of President Paul von Hindenburg in 1934, Hitler merged the roles of chancellor and president, assuming the title of Führer und Reichskanzler (leader and chancellor of the Reich), thereby making him the undisputed head of state and government.
