The Sturmabteilung was the original paramilitary wing of the Nazi Party. It played a significant role in Adolf Hitler's rise to power in the 1920s and 1930s. Its primary purposes were providing protection for Nazi rallies and assemblies, disrupting the meetings of opposing parties, fighting against the paramilitary units of the opposing parties, especially the Roter Frontkämpferbund of the Communist Party of Germany (KPD) and the Reichsbanner Schwarz-Rot-Gold of the Social Democratic Party of Germany (SPD), and intimidating Romani, trade unionists, and especially Jews.
