The 1950s are remembered fondly by most US history textbooks. Known as the Eisenhower era, the postwar years were considered a new height of prosperity, with median family purchasing power increasing as much as 30%. Unfortunately, that prosperity was not universally shared. While many Americans were celebrating the end of World War II, indigenous people on the Fort Berthold reservation were being forced into a settlement agreement over losses they would suffer due to the Garrison Dam. After this settlement they experienced an economic decline aggravated by drought, poor relationships with the surrounding governments, and their decreasing ownership of the land.
