Religion, Schism and Rivalry

A state religion is a political instrument

Between 1450 and 1750 several rulers made a deliberate choice about religious uniformity, and the exam expects you to treat that choice as policy with costs and benefits, not as inherited belief.

• Safavid Iran imposed Twelver Shi'ism as the state creed from 1501. It gave the dynasty a distinct identity, a loyal clerical class and a clear boundary against its neighbours — at the price of permanent hostility with the Sunni Ottomans, fought out at Chaldiran (1514) and along that frontier for two centuries.
• Mughal India ruled a Muslim dynasty over a Hindu majority and tried both answers. Akbar chose accommodation: he abolished the jizya tax on non-Muslims, promoted Rajputs into the officer corps, and sponsored debate under the principle of sulh-i kul, universal peace. Aurangzeb reversed it, reimposed the jizya and enforced orthodoxy — and faced revolts that drained the treasury.
• Sikhism, founded by Guru Nanak, grew in Punjab out of this meeting of traditions: one formless God, rejection of caste and of ritual specialists.

Europe splits, then invents a workaround

Luther's challenge of 1517 spread at the speed of the printing press and stuck where princes found it useful — a break with Rome meant church lands and independence from a distant authority. The Catholic Reformation answered with the Council of Trent, the Jesuits and new missionary orders that carried Catholicism to Asia and the Americas.

A century of religious warfare ended with the Peace of Westphalia (1648), whose practical result was that each ruler settled religion within his own territory. Religion did not disappear from politics; it was subordinated to the state.

The pattern to carry into an essay

Uniformity buys cohesion and a reliable clergy; toleration buys tax revenue and quiet from the majority. Rulers chose according to whether their main threat was internal or on the border.
