Ministry of the Interior (Argentina)

The Ministry of the Interior was one of the first five cabinet ministries formed by the first president of the Argentine Confederation, Justo José de Urquiza, The first interior minister was Benjamín Gorostiaga. When Argentina became a republic after the Confederation was dissolved, Guillermo Rawson was the first Minister of Interior appointed by then president Bartolomé Mitre. The name of the ministry remained unchanged for over a century until the presidency of Juan Domingo Perón, when it was merged with the Justice portfolio under the administration of Ángel Borlenghi. The military administration of Eduardo Lonardi restored the ministry its former name in 1955, and it was not until 2012 during the presidency of Cristina Fernández de Kirchner that an additional portfolio, this time that of the transport ministry, was incorporated into the Interior portfolio. The successive administration of Mauricio Macri added further responsibilities, merging the ministry with public works and housing. In 2019, President Alberto Fernández reorganized the cabinet ministries and separated the public works and housing responsibilities from the Interior Ministry, rendering back to its original name again. After President Javier Milei took office in 2023, the ministry was downgraded into a secretariat as part of his pledge to reduce public deficits and the size of the government. Milei reversed the decision in September 2025 amid efforts to build alliances with opposition governors following his party's defeat in the 2025 Buenos Aires provincial election. ==Attributions and structure==
