The correct answer is the Union League.
This organization was formed during the Civil War (1861-1865). The goal of this organization was to promote the policies and ideas of President Abraham Lincoln. Along with this, the Union League wanted Southerners to remain loyal to the Union rather than seceding and joining the Confederate States of America.
The Native Americans resisted by basically doing rebellions. They would raid places and burn down places and etc, until they got what they wanted. Even in some places their efforts were so impactful laws were changed.
