The Act of Uniformity was a law passed in England in 1559 during the reign of Queen Elizabeth I. It aimed to establish a standard form of worship in the Church of England, promoting the use of the Book of Common Prayer. This act was part of the broader English Reformation, which sought to unify religious practices and reduce conflicts between Catholics and Protestants. The Act required all clergy and churchgoers to adhere to the prescribed liturgy and rituals. Failure to comply could result in fines or other penalties. This legislation played a crucial role in shaping the religious landscape of England and reinforcing the authority of the Church of England.
