Pedro Eugenio Aramburu Silveti (May 21, 1903 – June 1, 1970) was an Argentine Army general who was the dictator of Argentina from November 13, 1955, to May 1, 1958.

The Revolución Libertadora which overthrew Juan Perón was triggered in part by his actions towards the press, as well as the imprisonment of opposition leaders and economic instability.

For example, Perón incited his followers to wreck the offices and printing presses of newspapers who criticized him and he jailed the leader of the opposition, Ricardo Balbin, of the Radical Civic Union party.

The fragility of Argentine democracy was shown when Illia was overthrown in 1966 by a military coup led by General Juan Carlos Onganía.

On May 29, 1970, at noon, Aramburu was snatched from his apartment in Buenos Aires by two members of Montoneros posing as young army officers.
