Pedro Lascuráin was the foreign minister in Francisco I. Madero's cabinet. On February 18, 1913, General Victoriano Huerta overthrew President Madero. Lascuráin was one of the individuals who convinced Madero to resign the presidency when Madero was being held prisoner in the National Palace, claiming that his life was in danger if he refused.
Lascuráin was thus president for less than one hour (sources quote figures ranging from 15 to 55 minutes). This makes his presidency the shortest in world history, above that of Venezuelan politician Diosdado Cabello. Huerta subsequently offered him a post in his cabinet, but Lascuráin declined. He retired from politics and began practicing again as a lawyer.
Lascuráin received a law degree in 1880 from the Escuela Nacional de Jurisprudencia in Mexico City. He was mayor of Mexico City in 1910 when Madero began his antireelectionist campaign against Díaz. Lascuráin was a supporter of Madero, and after the later was elected president to replace Díaz, Lascuráin served twice as foreign secretary in Madero's cabinet (April 10, 1912 to December 4, 1912 and January 15, 1913 to February 18, 1913). In between the two terms he was again mayor of Mexico City. As foreign minister he had to deal with the demands of U.S. Ambassador Henry Lane Wilson, who was later involved in planning Huerta's coup.
Lascuráin was the director of the Escuela Libre de Derecho, Mexico City's top law school, for 16 years, and he published extensively on commercial and civil law.
