Beer Hall Putsch
Hitler chose to do this for many reasons. The Weimar Republic of Germany was weak because of fighting between right and left-wing parties. Inflation had also left the Weimar Republic with very little support from the people, or money to keep working (paying bills, or even paying pensions and wages). This happened because when Germany lost World War I, other countries made Germany pay for the entire war, and Germany had to make taxes very high so it could pay for the war. This hurt the economy of Germany.
