How had the SA helped Hitler to power by 1934?

On 2nd August 1934, Adolf Hitler combined the state offices of Chancellor and President to create the title 'Fuhrer', and the SA (also known as the Brownshirts) played a significant role in this. They were a Nazi paramilitary group created by Hitler, effectively as a private army, after he took over the Nazi party in 1919. By 1924, they had 2.5 million members to the German army's 100000 and were led by Ernst Rohm. On 8th November 1923, Hitler and the SA stormed a meeting of the Bavarian government in Munich with the aim to take over the government and march on Berlin. This Beer Hall putsch is an example of how the SA supported Hitler during his rise to power by spreading the Nazi message of nationalist politics and inspiring fear, which later became a key factor in Hitler's control of the state. Even during the election campaigns of 1933, the SA terrorised people who tried to show support for opposing parties.
