Answer:
American Indians who lived in the West tried to prevent settlers from moving onto their territory.
Explanation:
American Indians previously occupied the west and viewed settlers as invaders. However, resisting the encroachment of the settlers proved very difficult. The American Indians were forced onto reservations and the American settlers began to systematically kill the buffalo herds to try to weaken the American Indian position. The settlers broke many of the treaties the US government had established with the American Indians in the West, further taking their land. Many heroic American Indians like Sitting Bull and Crazy Horse made courageous efforts to save their people but unfortunately many communities were pressured onto reservations or assimilated and suffered violence.
Answer: A. The abolitionist movement grew stronger.
<em>Dred Scott v. Sandford (1857)</em> was a landmark decision by the United States Supreme Court. It held that black people whose ancestors were imported into the U.S., whether enslaved of free, could not be American citizens. Therefore, they could not sue in federal court. Moreover, it ruled that the federal government had no power to regulate slavery in the territories acquired after the creation of the United States.
The decision was controversial, and greatly opposed by abolitionist groups. It strengthened the abolitionist movement and may have been a catalyst for the American Civil War.
