Hitler and Nazi Germany strongly opposed communism.

Hitler repeatedly described Marxism and Bolshevism as the greatest threats to the German and Aryan races. He claimed that communism was a “Jewish conspiracy.”
After the Nazis came to power in 1933, they immediately banned the German Communist Party (KPD), arresting tens of thousands of members and left-wing figures.
The Reichstag fire case (1933) was used by the Nazis as an excuse to carry out large-scale persecution of communists.
Many members were sent to concentration camps. The Nazis’ “Night of the Long Knives” operation (1934), although mainly targeting left-wing elements within the party, nonetheless continued to systematically purge any left-wing or communist tendencies overall.
In 1936, Germany, Japan, and Italy signed the Anti-Comintern Pact, explicitly targeting the Communist International.
In June 1941, Hitler launched Operation Barbarossa (the invasion of the Soviet Union). This was his long-planned “living space” war, one of whose core goals was to destroy the communist regime and seize the eastern territories. In his speeches, he repeatedly called it a “holy war against Bolshevism.”
Throughout his life, Hitler consistently regarded communism as one of his top ideological enemies. In Nazi propaganda, “anti-Bolshevism” was one of the most common slogans. After the Nazis took power, Germany quickly shifted from the state of confrontation between communism and Nazi street violence during the Weimar Republic to the comprehensive suppression of communism.
