Promoted and introduced by Dictator Trujillo , through the 1954 concordat the Church obtained control over marriage and religious instruction. With the signing of the concordat great benefits were granted to the Catholic Church like access to public funds and exemption from import duties. It allowed the creation of dioceses, and bishoprics were established in Santiago and the Vega. Until then there had been only one hierarchy in the country which was the Archbishopric of Santo Domingo. Religious instruction was also established in public schools. Religious marriage was made official and divorce was prohibited between those who had been married by the Church. Other religions were at a disadvantage compared with the Catholic.
