Nicolaus Olahus (Latin for Nicholas, the Vlach; Hungarian: Oláh Miklós; Romanian: Nicolae Valahul); 10 January 1493 – 15 January 1568) was the Archbishop of Esztergom, Primate of Hungary, and a distinguished Catholic prelate, humanist and historiographer. Olahus was particularly active in the Counter-Reformation; even before his elevation to the Archbishopric of Esztergom, he had been a very zealous opponent of the new Protestant teachings. As Primate of Hungary he threw himself with renewed energy into the conflict, aiming especially at the restoration of ecclesiastical discipline, the reformation of the clergy, and the establishment of new schools. The mountain cities of Upper Hungary, in which the doctrines of the Reformation had made considerable progress, attracted his particular attention. He organized a visitation of the archdiocese, which he in great part conducted in person, besides convoking, with a similar intention, a number of diocesan synods. The first of these synods was held in 1560 at Nagyszombat; during its closing session he promulgated a code of dogmatic and moral instructions, intended for the clergy, published during that and the following year. In 1561 a provincial synod was held, likewise at Nagyszombat, to discuss the participation of the bishops of Hungary in the Council of Trent, which had just re-convened. While it is not certain whether Olahus took part in the Council, or if he promulgated in Hungary its decrees of 1562 and 1564, it is known that he followed its deliberations with close attention and put in practice some of its decisions. In 1563 Olahus submitted to the council a lengthy memorial, in which he urged the importance of dealing with the critical situation of the Hungarian Church and describing in strong language the efforts he had made to overcome the demoralization that had seized on the clergy. It was particularly through school reform and the proper instruction of youth that he hoped to offset the progress of the Reformation. He restored the Cathedral school at Esztergom, which had fallen into decay when the city had been captured by the Turks; he transferred it, however, to his archiepiscopal city of Nagyszombat and confided it to the Jesuits, whom he invited to Hungary in 1561, and who, through their preaching and spiritual ministry, profoundly influenced the religious life of the nation. Among the publications initiated by Olahus were the Breviarium Ecclesiæ Strigoniensis (1558), and the Ordo et Ritus Ecclesiæ Strigoniensis (1560). The revival of the custom of ringing the Angelus was due to him. As chancellor and confidant of Ferdinand I, Olahus possessed much political influence. In 1562 he acted as Regent. He was a diligent writer.
