The Test Act refers to a series of laws enacted in England during the 17th and 18th centuries, primarily aimed at restricting the rights of non-Anglicans, particularly Roman Catholics and Dissenters. The most significant of these laws was passed in 1673, requiring all public officials to declare their allegiance to the Church of England and receive the sacrament. This effectively barred many from holding public office. The Test Act was part of a broader effort to maintain the supremacy of the Anglican Church in England. Over time, it faced criticism and calls for reform, leading to its eventual repeal in the 19th century, which allowed greater religious freedom and participation in government for various faiths.
