From Francoist minister to Christian Democrat dissident
In 1951, caudillo Franco appointed him minister of National Education. He established a special commission to rehabilitate some teachers and scholars who were previously expelled from their tenures by the Francoism. His political stance was gradually sympathetic toward the Christian Democracy. In 1956 he confronted the minister of Interior about a students' riot and he was finally dismissed. Franco appointed him afterwards National Counselor with seat in the Parliament. He resigned from this office in 1965. Meanwhile, in 1963 he founded Cuadernos para el Diálogo, a political and cultural magazine that was very relevant for the Spanish political life of the 1960s and 1970s because it hosted the moderate debate about the future evolution of Spain toward a more pluralistic, participative and European-minded situation. Cuadernos para el Diálogo was the most dissident option within the legal narrow framework of freedom of speech allowed during the last decades of Franco's reign. Ruiz-Giménez himself was considered the leader of the Spanish Christian Democrats left wing. In June 1975 he joined the undergroundDemocratic Convergence Platform, which gathered a wide array of anti-Francoist organizations, including Social Democrats and Communists. Nevertheless, the Christian Democracy had very little option during the first democratic elections in 1977, as its political room was occupied mainly by the Suárez'sUCD. Ruiz-Giménez's Democratic Left joined the Christian Democratic Federation coalition, that dissolved after its meager 1 per cent of the ballots.
First Spanish Ombudsman
After his withdrawal from the political forefront, Ruiz-Giménez was appointed Ombudsman, the first one in holding this office in Spain. During his later years, he enjoyed a great prestige among both left and right. He involved in several humanitarian and human-rights NGOs, presided the Spanish Committee of UNICEF, vice-presided the Spanish Commission of Relief to Refugees, and has been awarded and decorated several times for his philanthropic activity.
