At this point the country was in the middle of the long Stroessner dictatorship, and these activists proposed several reforms: partisan freedom, respect for popular sovereignty, and an ethical conduct of politics.
On March 12 of the year the movement was founded, and the members of the latter published the "Note of the 17",[1] in which they demanded that the Governing Board of the Colorado Party adopt measures such as "the lifting of the State of Siege", and respect the "full validity of all freedoms".
In 1973, MOPOCO and the "epifanists" would separate, since the latter would found a new dissident group, the Asociación Nacional Republicana en el Exilio y la Resistencia (ANRER).
At this point, MOPOCO leader Agustín Goiburú also tried to hijack a Paraguayan military plane and land it in Punta del Este, Uruguay in order to expose the dictatorship's crimes, but this plan was foiled.
This movement grew in strength until the coup d'état of 2 and 3 February 1989, when Stroessner was deposed and replaced by his former confidant, Andrés Rodríguez Pedotti, with the support of the army.
