Explanation:

The Nazi Party’s meteoric rise to power began in 1930, when it attained 107 seats in Germany’s parliament, the Reichstag. In July 1932, the Nazi Party became the largest political party in the Reichstag with 230 representatives.In the final years of the Weimar Republic (1930 to 1933), the government ruled by emergency decree because it could not attain a parliamentary majority. Political and economic instability, coupled with voter dissatisfaction with the status quo, benefitted the Nazi Party.As a result of the Nazis’ mass support, German president Paul von Hindenburg appointed Hitler chancellor on January 30, 1933. His appointment paved the way to the Nazi dictatorship after Hindenburg’s death in August 1934.
