Secular state

A secular state is an idea pertaining to secularity, whereby a state is or purports to be officially neutral in matters of religion, supporting neither religion nor irreligion. A secular state claims to treat all its citizens equally regardless of religion, and claims to avoid preferential treatment for a citizen based on their religious beliefs, affiliation or lack of either over those with other profiles. Although secular states have no state religion, the absence of an established state religion does not mean that a state is completely secular or egalitarian. For example, some states that describe themselves as secular have religious references in their national anthems and flags, laws that benefit one religion or another, or are members of the Organisation of Islamic Cooperation and of the International Religious Freedom or Belief Alliance.
