Liberal interlude known as the Trienio liberal, but still the old system had not yet had its last gasp. Later, during the period known as the Ominous Decade, the Inquisition was not formally re-established, although, de facto, it returned under the so-called Congregation of the Meetings of Faith, tolerated in the dioceses by King Ferdinand. On 26 July 1826, the "Meetings of Faith" Congregation condemned and executed the school teacher Cayetano Ripoll, who thus became the last person known to be executed by the Inquisition. On that day, Ripoll was hanged in Valencia, for having taught deist principles. This execution occurred against the backdrop of a European-wide scandal concerning the despotic attitudes still prevailing in Spain. Finally, on 15 July 1834, the Spanish Inquisition was definitively abolished by a Royal Decree signed by regent Maria Christina of the Two Sicilies, Ferdinand VII's liberal widow, during the minority of Isabella II and with the approval of the President of the Cabinet Francisco Martínez de la Rosa. (It is possible that something similar to the Inquisition acted during the 1833–1839 First Carlist War, in the zones dominated by the Carlists, since one of the government measures praised by Conde de Molina Carlos Maria Isidro de Borbon was the re-implementation of the Inquisition to protect the Church). During the Carlist Wars, it was the conservatives who fought the liberals who wanted to reduce the Church's power, amongst other reforms to liberalize the economy. It can be added that Franco during the Spanish Civil War is alleged to have stated that he would attempt to reintroduce it, possibly as a sop to Vatican approval of his coup. The Alhambra Decree that had expelled the Jews was formally rescinded on 16 December 1968 by Spanish dictator Francisco Franco, after the Second Vatican Council rejected the idea that Jews are deicides. The prohibitions, persecution and eventual Jewish mass emigration from Spain and Portugal probably had adverse effects on the development of the Spanish and the Portuguese economy. Jews and Non-Catholic Christians reportedly had substantially better numerical skills than the Catholic majority, which might be due to the Jewish religious doctrine, which focused strongly on education, for example because Torah-Reading was compulsory. Even when Jews were forced to quit their highly skilled urban occupations, their numeracy advantage persisted. However, during the inquisition, spillover-effects of these skills were rare because of forced separation and Jewish emigration, which was
