 From the 1940s to the 1970s, the Navajo moved their settlements closer to Hopi land, causing the Hopi to raise the issue with the U.S government.This resulted in the establishment of "District 6" which placed a boundary around the Hopi villages on the first, second, and third mesas, thinning the reservation to .In 1962 the courts issued the "Opinion, Findings of Fact and Conclusions of Law and Judgment," which stated that the U.S government did not grant the Navajo any type of permission to reside on the Hopi Reservation that was declared in 1882; and that the remaining Hopi land was to be shared with the Navajo.
