Irreligion in Germany

Irreligion is prevalent in Germany. In a time of near-universal adoption of Christianity, Germany was an intellectual centre for European freethought and humanist thinking, whose ideas spread across Europe and the world in the Age of Enlightenment. Later, religious traditions in Germany were weakened by the twin onslaughts of Nazi rule during World War II and that of the Socialist Unity Party in East Germany during the Cold War. In common with most other European societies, a period of secularisation also continued in the decades that followed. While today Christianity remains prevalent in the west of Germany, in the east relatively few Germans identify with any religion whatsoever.

As of 2021, approximately 42% of Germans are irreligious, with a much higher concentration of irreligious citizens in the former East Germany. Eastern Germany, which was historically Protestant, is by far the least religious region in the world.
