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, religious skepticism, rationalism, secularism, and non-religious spirituality. These perspectives can vary, with individuals who identify as irreligious holding diverse beliefs about religion and its role in their lives.
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.
Antireligion is opposition to religion or traditional religious beliefs and practices. It involves opposition to organized religion, religious practices or religious institutions. The term antireligion has also been used to describe opposition to specific forms of supernatural worship or practice, whether organized or not. The Soviet Union adopted the political ideology of Marxism–Leninism and by extension the policy of state atheism which opposed the growth of religions.
Religion has been a major influence on the societies, cultures, traditions, philosophies, artistic expressions and laws within present-day Europe. The largest religion in Europe is Christianity. However, irreligion and practical secularisation are also prominent in some countries. In Southeastern Europe, three countries have Muslim majorities, with Christianity being the second-largest religion in those countries. Ancient European religions included veneration for deities such as Zeus. Modern revival movements of these religions include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and others. Smaller religions include Indian religions, Judaism, and some East Asian religions, which are found in their largest groups in Britain, France, and Kalmykia.

As of 2021, 11.7% of the population identified with Christianity ; 10.8% identified with other religious identities or beliefs. According to sociologist Jan Spousta, not all the irreligious people are atheists; indeed, since the late 20th century there has been an increasing distancing from both Christian dogmatism and atheism, and at the same time ideas and non-institutional models similar to those of Eastern religions have become widespread through movements started by various gurus, and hermetic and mystical paths.
Estonia, historically a Lutheran Christian nation, is today one of the least religious countries in the world in terms of declared attitudes, with only 14 percent of the population declaring religion to be an important part of their daily life.

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 tradition in Germany was 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.

Uruguay has been the least-religious country in South America due to nineteenth-century political events influenced by positivism, secularism, and other beliefs held by intellectual Europeans. The resistance of the indigenous population to evangelization, which prevented the establishment of religion during the colonial era, has also been influential. According to Nestor DaCosta (2003), irreligion has historically been a feature of Uruguayan identity.
