Estado Mayor Presidencial

During the administration of Francisco I. Madero, the Presidential General Staff operated based on the General Ordinance of the Army, which was issued on December 11, 1911. On June 26, 1916, Venustiano Carranza issued a decree to reorganize the General Staffs of the Constitutionalist Army, thus reinstating the name Presidential General Staff, which had been modified during the coup and authoritarian government of Victoriano Huerta. On March 15, 1926, during the presidency of General Plutarco Elías Calles, the Organic Law of the National Army and Navy was decreed, which established in its Article 33 the basis for the creation of the Presidential Aide-de-Camp, which continued to operate during the administration of Lázaro Cárdenas.^[4]

During the presidency of Manuel Ávila Camacho, on January 12, 1942, the Organic Law of the National Army and Navy of 1926 was amended, transforming the Presidential Aide's Office into the Presidential General Staff (EMP). On April 15, 1942, to address the situation imposed by World War II, the EMP Regulations were issued, assigning the organization the function of assisting the President of the Republic in the military, economic, legal, and moral preparation and organization of the country for war. At the end of the armed conflict in 1945, the organization resumed its original functions of providing security and logistical support to the President of the Republic.

On March 24, 1985, President Miguel de la Madrid amended the regulations of the Presidential Guard (EMP). On January 16, 2004, during the presidency of Vicente Fox, the new regulations for the Presidential Guard (EMP) were issued and published in the Official Gazette of the Federation on January 23 of the same year. These regulations updated the structure, organization, and operation of the EMP as a technical military body and as an administrative unit of the Office of the President to facilitate the fulfillment of its responsibilities.^[5][6]

According to Article 5 of the Presidential General Staff Regulations, for the fulfillment of its general missions, the EMP will be organized as follows:^{[8] [9]}
