The Indians were peacefully trying to prohibit immigration into the region.
Answer: Option B.
Step-by-step explanation:
The Battle of Little Bighorn In 1875, the United States ordered all nomadic Lakota and Cheyenne to return to the Great Sioux Reservation. This was established by the Treaty of 1868. A lesser portion of the tribes determined they would continue to be independent of U.S. government authority and maintain their nomadic way of life.
These nomadic people or this tribe would not be a hurdle or an obstacle to the immigration and to the people who would immigrate to this region. They would not be a hindrance to the immigration.
