Fransico Madero, a citizen from Northern Mexico, was not fond of Porfirio Diaz and decided to run against him in the next election after publishing a book that highly dismantled the power of Diaz. Upon becoming aware of the opposition he was running against, Diaz he acted hastily to have Madero arrested and imprisoned. The imprisonment made sure that Diaz would once again win the election and maintain his rule. However, once Madero was released from prison, he spurred a revolution in Northern Mexico that would eventually lead to the fall of Porfirio Diaz.
