Freedom of religion is a fundamental human right that allows individuals to practice their faith without interference or persecution from the government or other individuals. This right is protected in many countries' constitutions and international human rights documents.
Freedom of religion has been a contentious issue throughout history, with many instances of religious persecution, wars, and conflicts arising from differences in belief. The concept of religious freedom has evolved over time, with key milestones including the Edict of Milan in 313 AD, which granted religious tolerance in the Roman Empire, and the First Amendment to the United States Constitution, which explicitly prohibits the establishment of a state religion and guarantees free exercise of religion.
Several international treaties and declarations protect freedom of religion, including the Universal Declaration of Human Rights and the International Covenant on Civil and Political Rights. These documents affirm the right to freedom of thought, conscience, and religion for all individuals.
