Why did Hitler become Chancellor of Germany in January 1933?

This is a very typical question for history A-level exams and I would suggest that a student approached it in four factors. The factors that I propose caused Hitler to become chancellor are 1) The failure of the Weimar Republic and the anger at the Treaty of Versailles 2) The effects of Economic Depression on Germany 3) Nazi Propaganda and 4) Von Papen's political miscalculations. This is how I would begin to write the essay. President Hindenburg appointed Adolf Hitler as Chancellor on January the 30th 1933, after the Nazi Party had secured 230 out of 584 seats in the November 1932 election. Despite this, the Nazi’s still lacked a majority. Whilst some may argue the from the totalitarian historiographical standpoint that Hitler became chancellor because of Nazi terror, this essay argues it was the context of the great depression and the longer term zeitgeist of disillusionment with the Weimar Republic, which meant that the Nazis became the most popular party in the November 1932 election. With 15% of the German workforce unemployed by 1928 and the collapse of five major banks in 1931, the Nazis represented a hopeful alternative to the conventional parties. Other contributing factors involve the political miscalculations of Von Papen and the Nazi terror and propaganda, which attributed to their popularity and helped to destroy Weimar from within. However, the most compelling argument is that it was the longer-term context of economic depression and resentment of the Weimar Republic that caused 44% of the German electorate to vote for the NSDAP in the 1933 election, and inevitably gave Hindenburg the impetus to appoint Hitler as Chancellor.
