Chihuahua (state):

After the death of the president Benito Juárez in 1872, the first magistracy of the country was occupied by the vice-president Sebastián Lerdo de Tejada, who called for new elections. Two candidates were registered; Lerdo de Tejada and General Porfirio Díaz, one of the heroes of the Battle of Puebla which had taken place on May 5, 1862. Lerdeo de Tejada won the election, but lost popularity after he announced his intent to run for re-election. On March 21, 1876, Don Porfirio Díaz rebelled against President Sebastian Lerdo de Tejada. The Plan of Tuxtepec defended the "No Re-election" principle. On June 2, 1876 the garrisons in the state of Chihuahua surrendered to the authority of General Porfirio Díaz; Governor Antonio Ochoa was arrested until all the Lerdista forces were suppressed throughout the state. Porfirio Díaz then helped Tíras regain the governorship of the state of Chihuahua allowing for the Plan of Tuxtepec to be implemented. The victory of the Plan of Tuxtepec, gave the interim presidency to Jose Maria Iglesias and later, as the only candidate, the General Porfirio Díaz assumed the presidency on May 5, 1877. During the first years of the Porfiriato (Porfirio Díaz Era), the Díaz administration had to combat several attacks from the Lerdista forces and the Apache. A new rebellion led by the Lerdista party was orchestrated from exile in the United States. The Lerdista forces were able to temporarily occupy the city of El Paso del Norte until mid-1877. During 1877 the northern parts of the state suffered through a spell of extreme drought which were responsible for many deaths in El Paso del Norte.
