The United States had long recognized the government of Porfirio Díaz, once the U.S. recognized his government since he had first come to power by coup. As Díaz approached eighty years old, he gave an interview to a journalist working for a U.S. publication, saying he was not going to run in the scheduled 1910 elections. This set off a flurry of political activity in Mexico about presidential succession. For the U.S., it wanted the new president to continue Díaz's policies that had been favorable to U.S. business interests and produced stability domestically and internationally. Díaz reneged on his promise not to run, exiled the most viable candidate to continue his policies, General Bernardo Reyes and had the most popular opposition candidate, Francisco I. Madero jailed. After the November elections, political unrest in Mexico became open rebellion in Morelos and in northern Mexico. The Mexican Federal Army was unequal to the challenges of the insurgents. Díaz resigned and went into exile, an interim government was installed, and new elections were held in October 1911. These were won by Madero. Initially, the U.S. was optimistic about Madero. He had disbanded the rebel forces that had forced Díaz to resign; retain the Federal Army; and appeared to be open to policies favorable to the U.S., so that the U.S. supported the transition. The U.S. began to sour on the relationship with Madero and began actively working with opponents to the regime Wilson, who took office shortly after Madero's assassination in 1913, rejected the legitimacy of Huerta's "government of butchers" and demanded that Mexico hold democratic elections. After U.S. navy personnel were arrested in the port of Tampico by Huerta's soldiers, the U.S. seized Veracruz, resulting in the death of 170 Mexican soldiers and an unknown number of Mexican civilians.
