Answer:
Na década de 1870, uma corrida do ouro atraiu ondas de colonos para o território Sioux em Black Hills.
Explanation:
The Black Hills are a small mountain range that pops up in the Great Plains in South Dakota and Wyoming, so called for their dark appearance for those who look in the distance, given the trees in the middle of a seemingly barren and yellow plain.
The Indians have a long relationship with the Black Hills that became the center of their culture. Incidentally, in 1868, the United States government signed the Treaty of Fort Laramie, which basically made the Black Hills exempt from the presence of pale faces.
However, someone discovered gold in this area. And with the gold rush, the Indians were forced to migrate to other regions of South Dakota.
