When the U.S.
Supreme Court ruled that federal and territorial courts did not
have jurisdiction to try an Indian for the murder of another Indian
on a reservation, Congress responded by passing the Major Crimes
Act of 1885. The act defined nine major crimes, and later
expanded the original nine to fifteen, denying to Indians the very
'inalienable rights' that had sparked the War of Independence from
King George III in 1776.
