The Reformation was a period of significant religious and social changes in Europe during the 16th century. It was marked by a widespread rejection of the Catholic Church's authority and the emergence of various church denominations. Some synonyms used to describe this era include the Protestant Reformation, the emergence of Protestantism, the religious revolution, and the great religious reform. The critical changes that occurred during this time led to the formation of new religious movements, including the Anglican, Presbyterian, and Lutheran churches. The Reformation also influenced the development of modern Europe, including political and social movements such as democracy and human rights.
