Manuel Garza Aldape (April 6, 1871 – February 28, 1924) was a prominent attorney in Mexico City. From 1912 to 1913 he served as Secretary of Education, Secretary of State, and Secretary of Foreign Affairs for President Victoriano Huerta. Due to his disagreement with Huerta's policies, he was approached by an unknown individual one Sunday outside of a bullfighting arena. The individual had given him a letter written and signed by Victoriano Huerta asking him to leave Mexico in 24 hours or be killed, an event described in A Diplomat's Wife In Mexico by Edith Louise O'Shaughnessy (1916).[1]
