In 1879 Susette La Flesche (later Tibbles), whose Omaha name was Inshta Theumba (“Bright Eyes”), took up the cause of Standing Bear and the Ponca people, who had been forced to leave their Nebraska lands.
She joined Standing Bear on a speaking tour in the East and even spoke before the Senate to protest the Ponca removal.
Similarly, Sarah Winnemucca (later Hopkins), who had served as a scout for the U.S. Army in their 1878 war with the Bannock people, angrily protested the treatment of her own Piute people, who were forced to march from their Nevada home to a reservation in Washington State in the winter of 1878-79.
Winnemucca went to the capital to speak to the president about the injustices to her people. She also wrote a book, Life Among the Piutes: Their Wrongs and Claims.
Rosalie La Flesche Farley opposed her sister Susette La Flesche Tibbles and argued that self-government would protect the Omaha better than U.S. citizenship would.
The argument ended in 1887, when Congress passed a law that essentially forced Native Americans to give up tribal ownership of their lands in return for individually owned pieces of property and U.S. citizenship.
