Washunga was the leader of the Kansa tribe during the allotment period and had a distrust for white intentions during this time.
As a non-Christian conservative, he gained prominence when he was made tribal chief councilor about 1885.
During this time, Charles Curtis, a mixed-blood Kansas politician from the Kaw tribe, convinced his friend Washunga that the best course for Indians was to seek citizenship through individualized land allotments.
In 1902, Washunga and several Kansa chiefs arrived in Washington to sign an allotment treaty that Curtis had drawn up several months before.
Each individual was supposed to receive 450 acres.
Although already an old man, Washunga made sure that negotiations for the treaty were completed.
After the treaty was signed, he retired from the tribal politics.
He died at the age of about seventy-eight in 1908.
