Protestantism
The success of the Counter-Reformation on the Continent and the growth of a Puritan party dedicated to further Protestant reform polarised the Elizabethan Age. The early Puritan movement was a movement for reform in the Church of England. The desire was for the Church of England to resemble more closely the Protestant churches of Europe, especially Geneva. The later Puritan movement, often referred to as dissenters and nonconformists, eventually led to the formation of various Reformed denominations.
