The Sioux leaders on the Great Plains, Sitting Bull, and Crazy Horse vigorously opposed the U.S. government's attempts in the mid-19th century to constrain their people to Indian reservations. The Battle of Little Bighorn was fought between Sioux leaders and Cheyenne warriors who have outnumbered the federal troops led by Lieutenant Colonel George Armstrong Custer. Around two hundred soldiers died in the battle and U.S forces justified the event to showcase the wild nature of native Indians. And therefore the efforts to confine native tribes were increased after this event.
Hitler had always wanted to see Germany expand eastwards to gain Lebensraum or 'living space' for its people. After the fall of France Hitler ordered plans to be drawn up for an invasion of the Soviet Union. He intended to destroy what he saw as Stalin's 'Jewish Bolshevist' regime and establish Nazi hegemony.
