Desegregation Of The Ranks: How The United States Military Was The First Professional Organization To Integrate All Ethnic Groups, Matthew Lee Spiller

Masters Theses

A nation’s military has often been at the forefront of social progression. The Spartans, a military society, granted women a voice in government and a degree of autonomy over their own lives, while the Athenians—the founders of democracy—considered women second-class citizens with no control over their own affairs. The United States military is no different, striving to ensure fair and equal treatment of all ethnicities within the armed forces. In 1948, President Harry S. Truman issued Executive Order 9981, which desegregated the United States military—six years before the desegregation of public schools in Brown v. Board of Education (1954). This …
