Interwar Romania mostly ignored the Reformed Church, but after 1945 the regime branded it subversive, nationalized its schools and charities, and forced leaders to balance collaboration with covert resistance. Under tight surveillance clergy kept Hungarian identity alive through small acts of defiance; pastor László Tőkés’ refusal to yield his Timișoara pulpit ignited the 1989 revolution. Therefore, the Church’s story is central to understanding how Romanian society outlasted totalitarian rule.
