What this topic is asking
Topic 2.3 asks you to explain how Protestantism spread and diversified after Luther. The College Board wants you to know the major branches that emerged, Calvinism, the radical reformation (Anabaptists and others), and the English Reformation, how they differed from Lutheranism and from one another, and why Protestantism never became a single church.
Calvinism
The radical reformation
Some reformers thought Luther and Calvin had not gone far enough. The Anabaptists were the best-known radicals:
- They rejected infant baptism, insisting that only adults who consciously chose faith should be baptised.
- Many sought to separate church from state entirely and to live in voluntary communities of believers.
- A few embraced more extreme or violent visions, as at Munster, which alarmed authorities.
Because they challenged the social and political order, Anabaptists were persecuted by Catholics and mainstream Protestants alike. Their separatist ideas, however, influenced later traditions.
The English Reformation
England's break with Rome was different in origin: it began as a political and dynastic act, not a doctrinal revolt. Henry VIII wanted to annul his marriage to produce a male heir; when the pope refused, Henry broke with Rome and made himself head of the Church of England through the Act of Supremacy (1534). At first the new church kept much Catholic doctrine and ritual; only later did it become more Protestant. So England's Reformation was driven from the top, for political reasons, even as Protestant ideas spread among the people.
Why it mattered
The diversification of Protestantism is central to Unit 2. It shows that the Reformation was not one movement but many, sharing a rejection of papal authority and salvation by works yet divided over doctrine, baptism, and church order. These divisions, especially between Catholics and Calvinists, helped drive the wars of religion examined next.
Try this
Q1. What doctrine most distinguished Calvinism, and where was its model city? [Recall]

Q2. Explain how the English Reformation differed in origin from the continental Reformation. [Short explanation]
- Cue. It began as a political and dynastic act, Henry VIII breaking with Rome over his annulment and making himself head of the Church of England, rather than starting primarily as a doctrinal revolt.

A. Describe: Calvinism taught predestination, the doctrine that God has already chosen who will be saved (the elect), going beyond Luther's emphasis on faith.
B. Radical feature: Anabaptists rejected infant baptism, insisting on adult baptism, and many sought to separate the church from the state entirely.
C. Reason England differed: the English Reformation began as a political and dynastic act, Henry VIII breaking with Rome over his annulment, rather than primarily a doctrinal revolt.

A Long Essay Question (LEQ), scored on the 6-point rubric.
Thesis (1): "Protestantism was united in rejecting papal authority and salvation by works, but it fractured into rival movements (Lutheran, Calvinist, radical, Anglican) that differed sharply in doctrine and church order."
Contextualization (1): Luther's break and the spread of reforming ideas through printing.
Evidence (2): Calvinist predestination and Geneva; Anabaptist adult baptism and separatism; the political English Reformation under Henry VIII.
Analysis (2): explain HOW the movements shared a core yet diverged, then add complexity by weighing the shared anti-Catholic foundation against the deep doctrinal splits that set Protestants against each other.
