Secretariat of the Interior (Mexico)

Gustavo Díaz Ordaz Bolaños (Spanish pronunciation: [ɡusˈtaβo ˈði.as oɾˈðas]; 12 March 1911 – 15 July 1979) was a Mexican politician and member of the Institutional Revolutionary Party (PRI). He served as the President of Mexico from 1964 to 1970. Previously, he served as a member of the Chamber of Deputies for Puebla's 1st district, a senator of the Congress of the Union for Puebla, and Secretary of the Interior.

Díaz Ordaz was born in San Andrés Chalchicomula, and obtained a law degree from the University of Puebla in 1937 where he later became its vice-rector. He represented Puebla's 1st district in the Chamber of Deputies from 1943 to 1946. Subsequently, he represented the same state in the Chamber of Senators from 1946 to 1952 becoming closely acquainted with then-senator Adolfo López Mateos. Díaz Ordaz was a CIA asset, known by the cryptonym, LITEMPO-2.

The Secretariat of the Interior (Spanish: Secretaría de Gobernación, lit. 'Secretariat of Governance'; SEGOB) is the executive department of the Mexican government concerned with the country's domestic affairs, the presenting of the president's bills to Congress, their publication in the Official Journal of the Federation, and certain issues of national security. The country's principal intelligence agency, CNI, is directly answerable to the Secretary of the Interior. The Secretary is a member of the president's Cabinet and is, given the constitutional implications of the post, the most important cabinet member. Additionally, in case of both temporary and absolute absences of the president, the Secretary of the Interior assumes the president's executive powers provisionally. The Office is practically equivalent to Ministries of the Interior in most other countries (with the exception of the United States) and is occasionally translated to English as Ministry, Secretariat or Department of the Interior.

Adolfo Tomás Ruiz Cortines (Spanish pronunciation: [aˈðolfo ˈrwis koɾˈtines] 30 December 1889 – 3 December 1973) was a Mexican politician who served as President of Mexico from 1952 to 1958. A member of the Institutional Revolutionary Party (PRI), he previously served as Governor of Veracruz and Secretary of the Interior. During his presidency, which constituted the Mexican Miracle, women gained the right to vote, and he instituted numerous public health, education, infrastructure, and works projects.

A member of the Constitutional Army, Ruiz Cortines was the last Mexican president to have fought in the Mexican Revolution. He worked at the Ministry of Industry and Commerce during the administration of Adolfo de la Huerta and served as an official in the Department of Statistics from 1921 to 1935. Ruiz Cortines joined the Institutional Revolutionary Party and became Senior Official of the Government of the Federal District in 1935 and member of the Chamber of Deputies for Veracruz in 1937. In 1939 he was appointed treasurer of the presidential campaign of Manuel Ávila Camacho and worked as Governor of Veracruz from 1944 to 1948, a position he left to become Secretariat of the Interior during the administration of Miguel Alemán Valdés.
