Which group primarily comprised the Nazi Party's main support base during the late 1920s?

The main support base of the Nazi Party during the late 1920s was predominantly made up of middle-class business owners and farmers. This group was particularly attracted to the Nazi Party due to their concerns about economic instability, inflation, and the perceived threat of communism, which they believed could undermine their livelihoods. The Nazis promised to restore economic order and stability, which resonated with this demographic.

The middle class had been significantly impacted by the economic turmoil of the Weimar Republic, including the Great Depression that began in 1929. Many small business owners faced financial ruin, and farmers struggled with falling prices for their products. The Nazi Party’s platform offered appealing solutions, such as economic revitalization and a promise for a strong Germany, which helped them gain a substantial following among these groups.

While other groups such as university students, the working class, and wealthy landowners were involved in the political landscape, it was the middle class that formed the core of the Nazi Party's electoral support during this period. Their combination of economic interests and nationalistic sentiments significantly contributed to the Nazis' rise in power leading up to the 1933 election.
