In December 1966 the Spanish Council of Ministers agreed to prepare the Constitutional Conference. On October 30, 1967, said Conference was inaugurated. After the second phase of the Constitutional Conference (from April 17 to June 22, 1968), the Constitution (whose main editor was Miguel Herrero de Minon)^[1] was published in the Official Gazette of Equatorial Guinea on July 24, 1968, and was ratified in a popular referendum held on August 11^[2] under the supervision of a team of United Nations observers. 64.32% of the electorate voted in favor of the Constitution, which envisaged a government with a General Assembly and a Supreme Court with judges appointed by the president.^[3]

Officially, it was in force for four years, from its promulgation until July 1973, when a new Constitution was approved. However, it barely entered into force de facto, since in its period of application the country had just achieved independence under the command of Francisco Macías. In March 1969, in the midst of a serious crisis with Spain, he announced the existence of an attempted coup d'état, taking the opportunity to put the political opposition out of play (Bonifacio Ondó Edu, Atanasio Ndongo,^[4] Federico Ngomo, etc). In May 1971 he repealed part of its articles to strengthen his personal power and establish a one-party dictatorship, through Decree No. 115, (May 7, 1971). In it, Macías held "the Spanish neo-colonialists and imperialists responsible for two coup attempts, putting their traitorous African lackeys on the screen" and justified the repeal of part of the text by stating that the current Constitution, despite participating himself in its elaboration, it had been "prefabricated by Spain".^[5] Along the same lines, in July 1972 he promulgated a Constitutional Law declaring himself president of the country for life.

The text of the Constitution was organized around a Preamble, ten titles with 58 articles and a series of final provisions (three transitory and one complementary, the latter providing for the ratification of the text through the subsequent popular referendum) in accordance with the following structure:

• Preamble
• Qualification. I - THE STATE AND THE CITIZENS (Articles 1 to 8)
