Freedom of religion or religious liberty, also known as freedom of religion or belief (FoRB), is a principle that supports the freedom of an individual or community, in public or private, to manifest religion or belief in teaching, practice, worship, and observance. It also includes the right not to profess any religion or belief or not to practice a religion, often called freedom from religion.
Freedom of religion is considered by many people and most nations to be a fundamental human right. Freedom of religion is protected in all the most important international human rights conventions, such as the United Nations International Covenant on Civil and Political Rights, the American Convention on Human Rights, the European Convention on Human Rights, and the United Nations Convention on the Rights of the Child. In a country with a state religion, freedom of religion is generally considered to mean that the government permits religious practices of other communities besides the state religion, and does not persecute believers in other faiths or those who have no faith. The concept of religious liberty includes, and some say requires, secular liberalism, and excludes authoritarian versions of secularism.
