In 1956, they initiated the plan for the Vicosinos to gain collective ownership of the hacienda. This was one of the goals most advocated for by the Peruvian government.

This process instead took six years because of complications from the CPP, the gentry, and the beneficiaries who would be relinquishing control of Vicos.
