International Religious Freedom Day Date in the current year: October 27, 2026

Freedom of religion is the principle supporting the right to choose, practice, change, or reject a religion or belief without coercion or discrimination. This concept has probably existed for nearly as long as organized religion itself, yet it has only recently been recognized as a universal human right.

Throughout history, people in different parts of the world have been persecuted for practicing religions other than the dominant or state religion, though the extent of this persecution varies by country and era. In other words, freedom of religion certainly hasn’t been nonexistent throughout history, but the principle hasn’t been applied consistently.

The first British colonies in New England were founded by Puritans who strove to maintain religious homogeneity in their communities, so religious freedom was uncommon during the early colonial period. Roger Williams was forced to found the Providence Plantations (present-day Rhode Island) after being expelled from the Massachusetts Bay Colony for questioning the enforcement of religious conformity.

Maryland was the first colony to adopt freedom of religion as a principle two years before the founding of Providence Plantations. However, this principle was not consistently applied in the years that followed. Other early colonies that established religious freedom included Connecticut, Pennsylvania, and the previously mentioned Providence Plantations.

After the United States gained independence, the principle of freedom of religion was adopted in the First Amendment to the U.S. Constitution. This amendment prevents Congress from establishing an official religion or prohibiting the free exercise of religion. However, the definition of “free exercise” has been disputed. For instance, in 1879, the Supreme Court ruled that the polygamy practiced by some members of the LDS Church violated federal laws and was not protected by freedom of religion.

In 1998, the United States formally recognized religious freedom as part of its foreign policy when it adopted the International Religious Freedom Act of 1998. This legislation established the United States Commission on International Religious Freedom (USCIRF), a federal commission responsible for investigating religious freedom violations worldwide.

International Religious Freedom Day originated in the United States and is primarily observed there, though several other countries, including Canada, have also recognized it. The day is usually marked by government statements, advocacy campaigns, and other events and activities that highlight the importance of religious freedom.

International Religious Freedom Day should not be confused with National Religious Freedom Day, which is observed on January 16 by presidential proclamation. This day commemorates the adoption of the Virginia Statute of Religious Freedom on January 16, 1786.
