Irreligion in Iraq has a societal, political and historical background.
Although the Constitution of Iraq guarantees freedom from religious coercion, and states that all citizens are equal before the law without regard to religion, sect, or belief, irreligious people may encounter difficulties with the authorities.
After six years, with religious figures coming to power, the situation changed rapidly as the tide of religiosity receded.
According to various Iraqi thinkers, this occurred after the religious politicians came to power, and their role in sectarianism and state corruption, and by regularly occupying television slots to spread their agendas.
The increasing prevalence of atheism and agnosticism signals a tidal public opinion change.
