What situations in Germany allowed for the growth of the Nazi party?

Before the onset of the Great Depression in Germany in 1929–1930, the National Socialist German Workers' Party (or Nazi Party for short) was a small party on the radical right of the German political spectrum. In the Reichstag (parliament) elections of May 2, 1928, the Nazis received only 2.6 percent of the national vote, a proportionate decline from 1924, when the Nazis received 3 percent of the vote. As a result of the election, a "Grand Coalition" of Germany's Social Democratic, Catholic Center, German Democratic, and German People's parties governed Weimar Germany into the first six months of the economic downturn.
