What this topic is asking
Topic 3.3 examines religion in the age of land-based empires. It asks you to explain the continuities and changes in belief systems between about 1450 and 1750, and how religion shaped - and was shaped by - states and empires. The College Board names three developments in particular: the Protestant Reformation in Europe, the Sunni-Shia split between the Ottoman and Safavid empires, and the emergence of Sikhism in South Asia.
Change: the Protestant Reformation
The sharpest religious change of the period was in Europe.
The Reformation had political consequences far beyond doctrine:
- It fuelled religious wars and division across Europe.
- Rulers used it to assert control over the church in their lands (as in the English break with Rome).
- The Catholic Church responded with the Counter-Reformation, reforming itself and reaffirming doctrine.
Change: the Sunni-Shia divide
In the Islamic world, an older divide became a political fault line.
The Sunni-Shia split dated back to the early history of Islam, but in this period it took on imperial form. The Safavid Empire made Twelver Shia Islam its state religion, setting it against the Sunni Ottoman Empire. The two fought repeatedly, and religion became a marker of imperial identity as much as a matter of belief.
Change: the rise of Sikhism
A new religion appeared in South Asia.
Sikhism was founded by Guru Nanak (born 1469) in the Punjab. It taught belief in one God and rejected the caste distinctions and ritualism Nanak saw around him, drawing on elements of both Hinduism and Islam while remaining distinct from each. Over time the Sikh community developed its own institutions and, under later Gurus, a political and military identity.
Continuity: religion as a tool of rule
For all the change, one thing stayed constant.
Try this
Q1. Name the figure who began the Protestant Reformation and the year it is dated to. [Recall]
- Cue. Martin Luther, in 1517, whose challenge to the Catholic Church split Western Christianity.
Q2. Explain one continuity in the relationship between religion and state power across this period. [Short explanation]
- Cue. Rulers continued to use religion to legitimize their authority - the Sunni Ottomans, the Shia Safavids, and European monarchs claiming divine sanction - so religion stayed central to states even as specific beliefs changed.

AP 2017 (style)3 marksBriefly describe ONE religious change in the period c. 1450 to c. 1750. Briefly explain ONE way that change affected a state or empire. Briefly explain ONE continuity in religion across this period.Show worked answer →
A Short Answer Question (SAQ), 3 points, one per bullet.
A. Describe: the Protestant Reformation, begun by Martin Luther in 1517, which challenged the authority of the Catholic Church and split Western Christianity.
B. Effect: the Reformation fuelled wars and political division in Europe, and rulers used it to assert control over churches in their territories, as in the English break with Rome.
C. Continuity: rulers continued to use religion to legitimize their power, as the Ottomans did with Sunni Islam and the Safavids with Shia Islam, so religion remained central to state authority.
Each bullet must be concrete. "Religion changed" earns nothing; "Luther's Reformation split Western Christianity" earns the point.

A Long Essay Question (LEQ), scored on the 6-point causation rubric.
Thesis (1): "Religious developments deeply shaped politics, because the Reformation divided Europe and the Sunni-Shia split set the Ottomans against the Safavids, though rulers also used religion as a tool of legitimacy that served existing state interests."
Contextualization (1): situate religion within a period of large empires that legitimized rule through faith.
Evidence (2): the Protestant Reformation and the Catholic response; the Sunni-Shia rivalry of Ottomans and Safavids; the rise of Sikhism; Mughal religious policy.
Analysis (2): explain HOW religious division drove war and political realignment, then add complexity by noting that rulers often used religion instrumentally to consolidate power, so faith and politics shaped each other.
