After the death of Washunga in 1908, the Kaw people had no formal organization for many years. In 1922, Washunga's adopted daughter Lucy Tayiah Eads was elected principal chief. A council of eight members was also created. She was the first and only female chief. In 1928, the government agency to the Kaw was ended, and the buildings were sold. After that, the Kaw had no recognized government. This changed in 1959, when the federal government recognized them, and the tribe reorganized. The last Chief of the Kaw, Ernest Emmett Thompson, was elected in 1934. According to Dorothy Roberts, full-blooded Kaw women were forced to be sterilized by the Indian Health Service in the 1970s. In 1990, the Kaw wrote a new tribal constitution. They created a tribal court in 1992. In 2000, the tribe bought lands on their pre-1873 reservation near Council Grove, Kansas. This did this to create a park remembering their history in Kansas. They named it the Allegawaho Memorial Heritage Park.
