Cordobazo
The Cordobazo was a civil uprising in the city of Córdoba, Argentina, in the end of May 1969, during the military dictatorship of General Juan Carlos Onganía, which occurred a few days after the Rosariazo, and a year after the French May '68. Contrary to previous protests, the Cordobazo did not correspond to previous struggles, headed by Marxist workers' leaders, but associated students and workers in the same struggle against the military government.
On 29 May 1969 there was a general strike in Córdoba, which brought police repression and a civil uprising, an episode later termed the Cordobazo. The next day the CGT de los Argentinos, headed in Cordoba by Agustín Tosco, called for national strike.
