The Escobar Rebellion was a conflict in northern Mexico in 1929 during the Maximato, between the government forces of President Emilio Portes Gil and rebel forces under the command of General José Gonzalo Escobar.
 After some initial success in taking over several key cities in the northern half of the country, the Escobar rebels were decisively defeated in a major battle at Jiménez, Chihuahua, and were eventually swept aside by the advancing government forces under the command of General Calles.
The Bombing of Naco was an international incident which occurred in the border town of Naco, Arizona, during the 1929 Escobar Rebellion.
 While rebel forces were battling Mexican 'Federales' for control of the neighboring town of Naco, Sonora, the Irish mercenary and pilot Patrick Murphy was hired to bombard the government forces with improvised explosives dropped from his biplane.
 During the ensuing fighting, Murphy mistakenly dropped bombs on the American side of the international border on three occasions, causing significant damage to both private and government-owned property, as well slight injuries to several American spectators watching the battle from across the border.
 The bombing, although unintentional, is noted for being the first aerial bombardment of the contiguous United States by a foreign power in history.

Plutarco Elías Calles (] ; September 25, 1877 – October 19, 1945) was a Mexican general and politician.
 He was the powerful interior minister under President Álvaro Obregón, who chose Calles as his successor.
 The 1924 Calles presidential campaign was the first populist presidential campaign in the nation's history, as he called for land redistribution and promised equal justice, more education, additional labor rights, and democratic governance.
 Calles indeed tried to fulfill his promises during his populist phase (1924–26), but entered an anti-clerical phase (1926–28).
The Battle of Naco, or the First Battle of Naco due to a later siege was a battle of the Mexican Revolution between Constitutionalist forces and Mexican government forces.

Abdolreza Rahmani Fazli is the current Interior Minister.
 His term will be up August 2015, Elections for a new interior minister can be voted in by the majority of people or chosen by the head of Parliament.
 Due to the recent changes in the political spectrum and the way in which officials acquire political status Iran has become much more inclusive of the majority of people and allowing them to cast a vote.
 This means that even if the selection of the new Interior minister is a closed door private selection the majority of the people can still choose to vote that person out in which a special election would be held.
The Siege of Naco was a major battle fought in the border town of Naco, Sonora, Mexico, between March 31 and April 6, 1929, during the Escobar Rebellion.
 Following their capture of Cananea in 1928 and the drafting of the "Plan of Hermosillo", rebel forces under the command of General José Gonzalo Escobar occupied Agua Prieta and from there moved to take control of Naco, which at the time was a small, dusty village opposite of Naco, Arizona, occupied by government forces loyal to President Emilio Portes Gil.
 The rebels hoped to fund the revolution using the revenue generated by Naco and Agua Prieta, where there was a significant amount of public support for their cause.
