The Wounded Knee Massacre in 1890 primarily aimed to suppress which movement?

The Wounded Knee Massacre in 1890 was primarily aimed at suppressing the Ghost Dance movement, which was a religious movement among Native Americans that arose in response to the socio-political conditions and oppression they faced following U.S. expansion into their territories. The Ghost Dance was seen by U.S. authorities as a threat because it symbolized hope for Native Americans' spiritual revival and a return to their ancestral lands.

As tensions heightened between Native Americans and U.S. military forces, the Ghost Dance gatherings were often misinterpreted as preparatory actions for armed resistance. The massacre at Wounded Knee was a tragic culmination of these fears, as U.S. soldiers confronted a group of Lakota Sioux who were performing the Ghost Dance. This event resulted in a significant loss of life and was viewed historically as a brutal demonstration of U.S. government efforts to control and eliminate Native American cultures and movements perceived as challenges to their authority.

The other movements mentioned, such as the Civil Rights, Prohibition, and Labor movements, were not directly related to the events at Wounded Knee and occurred in different contexts and timeframes. Thus, the Ghost Dance movement is accurately identified as the target of suppression during the massacre.
