World War II essentially transformed Poland into a state dominated by a single religion. According to a 1991 government survey, Roman Catholicism was professed by 96 percent of the population. The practice of Judaism declined more dramatically than any other religion after the war, but the numbers of adherents of Greek Orthodox, Protestant, and other groups also fell significantly. Although the claim of religious affiliation signified different levels of participation for different segments of society (80.6 percent of professed Catholics described themselves as attending mass regularly), the history of Roman Catholicism in Poland formed a uniquely solid link between nationality and religious belief. As a result of that identity, Poland was the only country where the advent of communism had very little effect on the individual citizen's practice of organized religion. During the communist era, the Catholic Church enjoyed varying levels of autonomy, but the church remained the primary source of moral values, as well as an important political force. Of the 4 percent of Poles who were not Roman Catholic, half belonged to one of forty-two other denominations in 1991, and the rest professed no religion. The largest of the nonCatholic faiths was the Polish Autocephalous Orthodox Church. Although Poland returned to its tradition of religious tolerance after the communist era, jurisdictional issues complicated relations between the Orthodox and Roman Catholic churches.
