State atheism 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.
