President

Institutional context

The President of Argentina is the head of state and head of government. The office in its modern form dates to the 1853 constitution. From 1853 through July 1974 every holder was male — a span of 121 years.

Career path

María Estela Martínez de Perón (born 1931, known publicly as Isabel) was a nightclub dancer who married Juan Perón in 1961 during his exile in Madrid. She was selected as her husband's running mate for the 1973 Argentine presidential election and assumed the Vice-Presidency on 12 October 1973. The choice was made in part to preserve the political balance within the Peronist movement following the death of Eva Perón in 1952.

Appointment

Following Juan Perón's death on 1 July 1974 — three days after his return to office — Isabel Perón succeeded him as President of Argentina under the 1853 constitution's vice-presidential succession provision. She is the first woman to serve as head of state in the Americas, although she did not assume office through direct election.

Tenure

One year and nine months. Her tenure was characterised by accelerating economic crisis, the political-violence escalation associated with the so-called "dirty war," and the increasing autonomy of the armed forces. She was deposed by a military coup on 24 March 1976 and held under house arrest for five years before being permitted to leave for Spain.

Cluster context

Perón's 1974 succession is recorded as the first woman head of state in the Americas. Subsequent woman heads of state in the region (Chamorro Nicaragua 1990, Moscoso Panama 1999, Bachelet Chile 2006) reached office through direct election. The contrast between Perón's succession and the later electoral path is a methodologically important distinction the dataset preserves: succession-based firsts are a structurally different event from selection-mechanism-driven firsts.
