Which party was prominently attacked by the SA during Hitler's rise?

During Hitler's rise to power in Germany, the SA (Sturmabteilung, or Storm Detachment) played a significant role in the Nazi Party's tactics of intimidation and violence against political opponents. The SA was primarily tasked with protecting Nazi rallies and attacking rivals, creating an atmosphere of fear that would benefit the Nazis politically.

The Communist Party was a major target of the SA's aggression. The communists were seen as one of the most significant threats to the Nazis, both ideologically and politically. The SA engaged in violent confrontations with communist groups, aiming to disrupt their meetings, intimidate their supporters, and undermine their influence among the working-class electorate. This violence was a crucial component in the Nazis' strategy to combat leftist opposition and to consolidate their power.

In contrast, while the Social Democratic Party was also a rival, it did not experience the same level of violence as the Communist Party during the earlier years of Nazi rise. The National Socialist Party is the party led by Hitler, so it was not the target of attacks by the SA. The Liberal Democratic Party was less prominent and less directly engaged in confrontations during this critical period of political turbulence in Germany.
