On July 26, 1533, Francisco Pizarro’s Spanish conquistadors strangled to death Atahualpa, the 13th and last emperor of the Incas, thereby ending 300 years of Inca civilization. The conquistadors were greedy and murderous, but the Inca civilization, arguably, was worse: totalitarian and radically inegalitarian. But they made great high-mountain roads. (Arguments about infrastructure promoted by Big Government continue to this very day. And it is quite possible that an earlier civilization made the roadways, which the Inca merely renovated.)
On this day in 1948, U.S. President Harry S. Truman signed Executive Order 9981 desegregating the U.S. military.
