Strife

Frondizi allowed Peronist candidates to participate in elections for provincial governorships. One of them wins in the decisive province of Buenos Aires, and as a result Frondizi is overthrown. Strife within the military allows the president of the Senate, Jose Maria Guido, rather than the chief of the army, to ascend to the presidency in Frondizi's place. In September, various military factions have an armed confrontation over the control of a weak President Guido.
