The main impact that I can think of with regard to this question is that the Civil War helped to cause conflicts between Indians and the United States.
The Civil War took up a lot of government resources. Because of this, Native Americans in the Midwest weren't paid the way the treaties said they had to be. This led to conflicts between the US and the Indians, including a famous incident in Minnesota that ended with about 40 Sioux being hanged. It was also during the Civil War that the infamous Sand Creek Massacre happened.
There were also Indians who fought in the Civil War, mainly on the side of the South. But this had little effect other than on the individuals who fought.
Mainly, then, the Civil War helped cause conflicts to erupt because the US Government didn't have the resources to either keep the Indians happy or keep them suppressed.
The Civil war changed the lives of the American women because before it, they were mostly concerned with matters of their homes. With the Civil War, women because more involved with society by helping with volunteer brigades, working as nurses, cooking for troops, sewing, and washing uniforms, organizing fundraising campaigns to raise money to help with the war.
