The Dakota War of 1862 culminated in the execution of 38 Dakota Sioux men in Mankato, Minnesota, marking the largest mass execution in U.S. history. This event was a direct consequence of the conflict between the Dakota people and settlers, driven by broken treaties and economic hardship. The executions highlighted the tensions between Native Americans and the U.S. government, and they remain a significant chapter in the history of American Indian relations.

The Dakota War Executions at Mankato had a profound impact on protest poetry, particularly within Native American literary traditions. Poets like Louise McNeill and later writers addressed themes of injustice and cultural suppression, using their voices to advocate for indigenous rights.
