Irreligion is the absence or rejection of religious beliefs or practices. It encompasses a wide range of viewpoints drawn from various philosophical and intellectual perspectives, including atheism, agnosticism, skepticism, rationalism, and secularism. These perspectives can vary, with individuals who identify as irreligious holding a diverse array of specific beliefs about religion or its role in their lives.
In sociology, secularization is a multilayered concept that generally denotes "a transition from a religious to a more worldly level." There are many types of secularization and most do not lead to atheism, irreligion, nor are they automatically anti-thetical to religion. Secularization has different connotations such as implying differentiation of secular from religious domains, the marginalization of religion in those domains, or it may also entail the transformation of religion as a result of its recharacterization.
State atheism or atheist state is the incorporation of hard atheism or non-theism into political regimes. It is considered the opposite of theocracy and may also refer to large-scale secularization attempts by governments. To some extent, it is a religion-state relationship that is usually ideologically linked to irreligion and the promotion of irreligion or atheism. State atheism may refer to a government's promotion of anti-clericalism, which opposes religious institutional power and influence in all aspects of public and political life, including the involvement of religion in the everyday life of the citizen. In some instances, religious symbols and public practices that were once held by religions were replaced with secularized versions of them. State atheism in these cases is considered as not being politically neutral toward religion, and therefore it is often considered non-secular.

Irreligion is prevalent in Germany.

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 north, south, and west of Germany, in the east relatively few Germans identify with any religion whatsoever.
