How did the spread of Communism lead to the rise of Nazism in Germany?

After the Bolshevik Revolution in Russia, the Communist influence in Germany increased considerably. The Communists organised themselves effectively and succeeded in capturing a number of seats in Reichstag. Hitler warned the people that Communists of Germany would become the servants of their Russian masters and would follow the dictates of Communists.

He tried to persuade the people in Germany that Nazism alone could check the growing influence of Communists.
