as introducing "the modern American Indian novel", a pattern for future works by Native American authors. It is marked by its realism, as Mathews wanted to represent the Indian in a way that had not been recognized in European-American cultural stereotypes. The semi-autobiographical work is about Challenge "Chal" Windzer, a young Osage man of mixed-blood ancestry. After leaving home to study at the University of Oklahoma and serve in the military, Chal feels estranged when he returns to his tribal community. He suffers from alienation and hopelessness as his life takes a downward swerve. The novel is set during the turbulence of the oil boom that took place on Osage land in Oklahoma in the early 1920s, which generated great wealth for the many Osage enrolled citizens who had headrights. It depicts the frictions and disruption within the tribal community that accompanied this bonanza of wealth. In addition, it portrayed the swindles and numerous outright murders of Osage during the 1920s, a period they termed the "Reign of Terror", as white opportunists tried to get control of the Osage headrights. (Note: see Osage Indian Murders. Failing to get relief from local law enforcement, the Osage appealed to the federal government for help, as their people were still being killed. Extensive local and corruption has been documented in conspiracies to get control of Osage headrights, involving state many leading whites of the region: ranchers, lawyers, judges, doctors, police, undertakers, and more. Agents of the new Federal Bureau of Investigation were assigned to investigate the murders and successfully prosecuted three men, but many more crimes passed without investigation.) During the 1930s and the Great Depression, when Mathews was still living in his cabin, he was very politically active within the Osage Nation. As the people took advantage of the Indian Reorganization Act of 1934 and the Oklahoma Indian Welfare Act, Mathews helped the Osage Nation restore its self-government. He was elected to the Tribal Council, serving from 1934 to 1942. He helped found the Osage Tribal Museum, which opened in 1938 in Pawhuska, and donated numerous artifacts to it. From 1939 to 1940 Mathews lived and studied in Mexico on a Guggenheim Fellowship. In 1940, Mathews served as the United States representative to the Indians of the Americas Conference at Michoacan, Mexico. Later, Mathews concentrated again on his writing. His work Talking to the Moon (1945) is a retrospective account of the
