What the exam asks
College Board tests your ability to connect Cultural Developments and Interactions (CDI) with Governance (GOV) using the reasoning process of continuity and change over time (CCOT). Specifically, you must be ready to:
- Explain how the Protestant Reformation broke with existing Christian traditions and how both the Protestant and Catholic reformations contributed to the growth of Christianity.
- Explain how political rivalries between the Ottoman and Safavid empires intensified the split within Islam between Sunni and Shi’a.
- Explain how Sikhism developed in South Asia in a context of interactions between Hinduism and Islam.
- Explain continuity and change within belief systems from 1450 to 1750, especially how monarchs and emperors tied religion to state power.
Core ideas
The Protestant and Catholic Reformations in Europe
For centuries, the Roman Catholic Church served as the primary unifying institution in Western Europe, though monarchs and popes often clashed over political authority. In 1517, the German monk Martin Luther challenged Church practices—most notably the sale of indulgences (certificates pardoning sins)—by posting his 95 Theses.
- The Break (Change): Luther argued that salvation came through faith alone (sola fide), that the Bible—not the Pope—was the ultimate spiritual authority (sola scriptura), and that all believers held equal spiritual standing. Assisted by the printing press, vernacular translations of the Bible spread rapidly. Other reformers followed: John Calvin preached predestination, and King Henry VIII of England broke with Rome to establish the Anglican Church with the monarch as its head.
- Political Impact: European rulers used the Reformation to expand their power. German princes adopted Lutheranism to seize Church lands and weaken the Catholic Holy Roman Emperor, culminating in the destructive Thirty Years’ War (1618–1648) and the Peace of Westphalia, which allowed rulers to determine their state’s religion.
- The Catholic Reformation (Continuity and Growth): In response, the Catholic Church launched the Catholic Reformation (Counter-Reformation). At the Council of Trent (1545–1563), the Church reaffirmed traditional Catholic doctrines (such as papal authority and the seven sacraments) while ending abuses like the sale of indulgences. Newly founded missionary orders, especially the Society of Jesus (Jesuits) led by Ignatius of Loyola, revitalized Catholicism in Europe and spread Christianity across the Americas and Asia. Concurrently, Protestant denominations expanded across northern Europe and into North American colonies.
Ottoman–Safavid Rivalry and the Sunni–Shi’a Split
The division between Sunni and Shi’a Islam began in the 7th century over who should succeed the Prophet Muhammad, but between 1450 and 1750, imperial geopolitics hardened this theological divide.
- Safavid Empire (Shi’a): Founded in Persia by Shah Ismail I in 1501, the Safavid state declared Twelver Shi’ism the compulsory state religion. Ismail used Shi’ism to forge a distinct Persian identity, unify warring tribes, and legitimate his rule by claiming descent from the Prophet’s family.
- Ottoman Empire (Sunni): Neighboring the Safavids, the Ottoman Empire was a staunchly Sunni state. After conquering Mamluk Egypt and the holy cities of Mecca and Medina in 1517, Ottoman sultans like Selim I and Suleiman the Magnificent claimed the title of Caliph, presenting themselves as the supreme defenders of orthodox Sunni Islam.
- Intensification of the Split: Territorial competition over Mesopotamia and control of Silk Road trade routes merged with sectarian hostility. Both empires persecuted religious minorities representing the rival sect within their borders, issued religious decrees (fatwas) declaring the rival ruler a heretic, and clashed militarily at battles such as Chaldiran (1514).
