Mercedes Mariana "Nina" Aragonés de Juárez[2] (12 September 1926[1] – 25 July 2023) was an Argentine politician who was Governor of Santiago del Estero Province from 2002 to 2004. The wife of longtime governor and local caudillo[3] Carlos Arturo Juárez, Aragonés was the last head of a provincial state in Argentina removed from office through federal intervention.
Mercedes Aragonés de Juárez was born on 12 September 1926.[1] She was the second-ever woman to serve as governor of a province in Argentina, and the first in Santiago del Estero.[4] She assumed office upon the resignation of Governor, in whose ticket Aragonés had been elected as vice-governor.[5] In 2004, facing numerous accusations of corruption and embezzlement, she was removed from office by President Néstor Kirchner through federal intervention, a constitutional mechanism wherein the federal government of Argentina can intervene in a provincial government.[6]
In addition to the governorship, she held the positions of National Deputy representing Santiago del Estero, Minister of Women's Affairs, and president of the provincial chapter of the Female Peronist Party.[2]
Aragonés de Juárez died on 25 July 2023, at the age of 96.[7]
