Mexican neutrality in the Great War reflected a hostility toward the U.S., due to several earlier U.S. interventions in Mexican internal affairs. In February 1913, Victoriano Huerta had conspired with the U.S. ambassador Henry Lane Wilson to oust Francisco I. Madero from the presidency of Mexico. The "coup d'état" was the culmination of violence in Mexico City, known as the Ten Tragic Days ("La decena trágica"), in the waning days of the William Howard Taft presidency. President Woodrow Wilson also ordered the invasion of Veracruz in 1914, resulting in the death of 170 Mexican soldiers and an unknown number of civilians.
