A prolific historian, a professor of the Andreian Seminary in Sibiu, parish priest of Săliștea and an archpriest of Mărginimea Sibiului, a professor of the ‘King Ferdinand I’ University in Cluj, a titular member of the Romanian Academy, a talented publicist, a co-founder of the Institute of National History in Cluj, a deputy in the Parliament of Greater Romania, a minister in the Averescu and Goga-Cuza governments, a patriot and victim of the Bolshevik regime in the 1950s’ Romania, Ioan Lupaș is a scholar with the aura of a saint. Fr. Lupaș is part of the admirable generation of those who committed themselves with all their power and selflessness to the national movement of the Transylvanian Romanians, those who achieved the Union of Transylvania, Banat, Crișana and Maramureș with the Kingdom of Romania on 1 December 1918 and then fought for the consolidation of national unity during the interwar period. Lupaș is part of the leading gallery of the makers of Greater Romania, and one of the few historians-participants who later wrote relevant pages about the astral event in which they were active participants. The study provides a brief biography of Ioan Lupaș, focusing on the activity of the archpriest at the time of the First World War, his involvement in the organization of the Great National Assembly of Alba Iulia, and the way in which he subsequently remembered the events and feelings experienced in the year of the ‘fortunate fulfilling of long-awaited goals’ and of ‘thoroughly well-deserved triumph’.
