The political-cultural gala was held in this capital, and as part of it, videos and images about the literacy campaign were transmitted, a cultural deed that was carried out under the leadership of Fidel Castro.
On December 22, 1961, Cuba was proclaimed an illiteracy-free territory, after a campaign that was considered an epic of the nascent Revolution and popular participation.
It was the prelude to the transformations by which Cuba was populated with schools, institutes, polytechnics, centers for special education, sports, pedagogy and universities.
The number of educators exceeded 300,000, including cadres and administrative workers.
The illiterate rate was reduced to 3.9 percent of the total population, and was described as unprecedented due to various reasons, as it included some 25,000 Haitian residents who did not speak the Spanish language.
On December 20, 1961, the campaign was officially over, so in just one year, 707,000 people benefited from it and Cuba was among the countries with the lowest illiteracy rate in the world.
