NAZI Party held their 1st major meeting on this date, 24FEB, in 1920
In February of 1920, Hitler urged the German Workers' Party to holds its first mass meeting. He met strong opposition from leading party members who thought it was premature and feared it might be disrupted by Marxists. Hitler had no fear of disruption. In fact he welcomed it, knowing it would bring his party anti-Marxist notoriety. He even had the hall decorated in red to aggravate the Marxists.
On February 24, 1920, Hitler was thrilled when he entered the large meeting hall in Munich and saw two thousand people waiting, including a large number of Communists.
