With the successful advance of the Allies in 1918, Germany realized that it was not possible to win the war and signed an armistice treaty to end the conflict.
Once his imperial government collapsed, civil unrest and labor strikes spread across the nation. Fearing a communist revolution, important parties came together to contain the revolts, founding the Weimar Republic.
One of the new government's first tasks was to implement a peace treaty imposed by the Allies. In addition to losing more than a tenth of its territory, and dismantling its army, Germany had to take responsibility for the war and pay damages, weakening its already weakened economy.
All of this was seen as a humiliation by many nationalists and veterans. They mistakenly believed that the war could have been won if the army had not been betrayed by politicians and protesters.
For Hitler, these views became an obsession and his fanaticism and paranoid delusions led him to place the blame on the Jews. His words echoed in a society with many anti-Semites. At that time, thousands of Jews had joined German society, but many Germans considered them to be intruders.
After the First World War, the success of the Jews led to unfounded accusations of subversion and speculation with the war. We cannot fail to stress that these conspiracy theories were born out of fear, anger and intolerance, not facts. However, Hitler was successful with them. When he joined a small nationalist political party, he launched him into the leadership of the party and dragged more and more crowds.
Combining anti-Semitism with political resentment, the Nazis denounced communism and capitalism as international plots by Jews to destroy Germany.
The Nazi Party was initially not popular. After unsuccessfully trying to overthrow the government, the party was banned and Hitler was arrested for treason. But, after being released a year later, he immediately started to rebuild the movement.
