Unit 1.3 — South and Southeast Asia, c. 1200–1450
Topic 1.3: the Delhi Sultanate and Vijayanagara in South Asia, the Khmer Empire and Majapahit in Southeast Asia, and how trade — not conquest — spread Islam through the maritime world.
Topic 1.3 covers South and Southeast Asia, c. 1200–1450 — a region defined by the collision of Hindu, Buddhist, and Islamic political and religious traditions, all tied together by some of the busiest maritime trade routes in the world.
The Delhi Sultanate — Islam rules a Hindu-majority region (again from Topic 1.2)
You met the Delhi Sultanate (1206–1526) already in Topic 1.2 as an example of Islam spreading by conquest. Here's what to add for South Asia specifically:
- It imposed the jizya, a tax on non-Muslim subjects — the same practical, tolerate-and-tax approach seen elsewhere in Dar al-Islam, rather than forced conversion.
- Unlike China, it never built an efficient centralized bureaucracy — a useful contrast point with Topic 1.1's Song/Yuan/Ming administrative systems.
- It successfully blocked Mongol invasions of South Asia — one of the few regional powers that did.
Vijayanagara Empire — the Hindu counterweight
In southern India, the Hindu Vijayanagara Empire rose partly as a political and cultural response to Muslim expansion from the north. Rulers like Krishna Deva Raya sponsored massive temple-building projects and Sanskrit scholarship, reviving Hindu devotional (bhakti) culture. But — and this is the exam-testable nuance — Vijayanagara was pragmatic, not purely oppositional: it employed Muslim soldiers and traded freely with Muslim merchants. Religious rivalry and practical cooperation coexisted.
Southeast Asia: maritime states built on trade, not just land
Southeast Asia in this period looked different from South Asia — power here came from controlling straits and ports, not just farmland:
- The Khmer Empire, centered on the massive temple complex at Angkor Wat, was a land-based Hindu-then-Buddhist kingdom in present-day Cambodia — its scale (Angkor was possibly the largest pre-industrial urban settlement in the world) shows how much wealth Southeast Asian rice agriculture could generate.
- Majapahit, based in Java, and the fading remnants of the earlier trading state Srivijaya were maritime powers — their wealth and influence came from taxing and controlling the shipping lanes through the Strait of Malacca, the single most important chokepoint connecting the Indian Ocean to the South China Sea.
How Islam reached Southeast Asia
This connects directly to Topic 1.2's three-mechanism framework: in Southeast Asia specifically, Islam spread almost entirely through trade and Sufi missionaries, not conquest. Muslim merchants who controlled valuable trade goods had real influence over local rulers and port populations who wanted access to those trade networks — a soft-power spread very different from the Delhi Sultanate's military conquest of North India.
Why this matters for the exam
Topic 1.3 is built for comparison questions. Expect to be asked to compare: (1) how Islam spread in South Asia (conquest, Delhi Sultanate) versus Southeast Asia (trade/Sufism, no conquest) — direct application of Topic 1.2's framework to two different sub-regions; and (2) land-based agricultural states (Khmer) versus maritime trade states (Majapahit, Srivijaya) as two different paths to regional power. Both comparisons show up constantly across the whole AP World History exam, not just this unit.
