Islam's Influence on Southeast Asia: Trade, Culture, and Law

Islam arrived in Southeast Asia peacefully via maritime trade networks from the 7th century onward, accelerating after the 13th century with the rise of Muslim sultanates. Today, Indonesia (world's largest Muslim population), Malaysia, and Brunei are majority-Muslim; significant minorities exist in Southern Philippines, Southern Thailand, Singapore, Cambodia, Vietnam.

• Arabic loanwords permeate Malay/Indonesian (kitab, masjid, zakat, halal, maaf, selamat).

3. Architecture

• Mosques: tiered roofs (Meru) in Java/Sumatra; domes/minarets in Malay Peninsula (Ottoman/Mughal influence).
• Palaces (kraton), tombs (makam) blend Islamic geometry with local motifs.

4. Arts & Crafts
