In the mid-twentieth century, decolonization fundamentally changed foreign relations as it converged with Black and Brown freedom movements, the establishment of the United Nations and NATO, an exploding Cold War, and a burgeoning world human rights movement. Dramatic events swept through Africa at a furious pace, with fifty nations gaining independence in roughly fifty years, as the struggle against colonial rule fundamentally reshaped the world and the lives of the majority of the world's population. Meanwhile, the United States emerged as the most powerful and influential nation in the world, with the ability—politically, economically, militarily, and morally—to help or hinder the transformation of the African continent.    Tears, Fire, and Blood offers a sweeping history of how the United States responded to decolonization in Africa. James H. Meriwether explores how Washington, grappling with national security interests and racial prejudices, veered between strengthening African nationalist movements seeking majority rule and independence and bolstering anticommunist European allies seeking to maintain white rule. Events in Africa helped propel the Black freedom struggle around the world and ultimately forced the United States to confront its support for national ideals abroad as it fought over how to achieve equality at home.
