Introduction
The years 1914 to 1989 encompass two world wars, economic upheaval, the rise and fall of communism, and profound social change across Europe. Religious participation, measured principally through church attendance, membership rolls and affiliation rates, underwent noticeable transformation during this time. This essay examines the extent of decline, drawing on evidence from both Western and Eastern Europe. While broad trends point to reduced involvement in organised religion, particularly after 1945, the process was uneven and shaped by differing political contexts. The discussion therefore assesses the strength of secularisation alongside temporary revivals and regional variations.
Impact of the World Wars on Religious Observance
The outbreak of the First World War initially produced a modest upsurge in religious activity in several combatant nations. Soldiers and civilians alike sought spiritual reassurance amid mass casualties, and national days of prayer drew large congregations in Britain and Germany. However, the prolonged nature of the conflict and its unprecedented death toll ultimately undermined confidence in established churches. Post-war surveys in France and Britain recorded falling Sunday attendance from the mid-1920s onward, especially among urban working-class populations (McLeod, 2007). Similar patterns emerged after 1945. Although the immediate post-war years witnessed a short-lived return to pews in some Western countries, the longer-term effect of total war was accelerated detachment from institutional religion. Wartime disruption of parish life, combined with widespread bereavement, contributed to a lasting scepticism rather than renewed devotion.
Secularisation in Western Europe after 1945
From the 1950s, Western European states experienced sustained economic growth, welfare expansion and cultural liberalisation. These conditions coincided with marked reductions in religious participation. In Britain, Church of England Easter communicants dropped from roughly 2.3 million in 1960 to under 1.7 million by 1980. Comparable declines occurred in the Netherlands and Scandinavia, where state churches lost both members and regular worshippers (Brown, 2001). Explanations centre on generational change: cohorts born after 1945 proved markedly less likely to attend services than their parents. Rising educational levels and altered gender roles further eroded traditional observance. Nevertheless, the process was rarely total. Davie (2000) notes that private belief often persisted even as public practice diminished, producing a pattern of “believing without belonging”. This qualification suggests that decline in participation was real but did not equate to wholesale disappearance of religious sentiment.
Religion under State Socialism in Eastern Europe
In Eastern Europe the trajectory of religious participation diverged sharply because of communist policies. Regimes in the Soviet Union, Poland and the German Democratic Republic imposed varying degrees of restriction on churches after 1945. Official statistics showed sharp falls in registered membership and seminary numbers, yet actual observance proved more resilient than state propaganda claimed. In Poland, the Catholic Church retained substantial popular loyalty, evidenced by mass pilgrimages and high attendance at key festivals throughout the 1970s and 1980s. Underground or semi-tolerated congregations in Hungary and Czechoslovakia maintained discreet worship despite surveillance. Thus, while overt participation often declined under pressure, enforced secularisation coexisted with covert continuity. The period therefore cannot be described as uniformly one of decline when state coercion rather than voluntary choice drove much of the change.
Conclusion
Between 1914 and 1989 religious participation in Europe diminished overall, most evidently in Western countries after the Second World War. Wars, secular social trends and, in the East, political repression each contributed to lower attendance and affiliation. Yet the decline remained incomplete and uneven: private belief endured in the West, while in parts of Eastern Europe institutional religion retained surprising vitality. The period is therefore best characterised as one of substantial but far from absolute reduction in organised religious practice.
