Which factors contributed to Islam's diffusion across the Eastern Hemisphere?

• A. War, trade, missionaries, and migration
• B. Isolation and geographic barriers
• C. Monasticism and silent meditation
• D. Colonial governance and taxation

Answer: (A)

Islam spread across the Eastern Hemisphere through a mix of contact, movement, and persuasion rather than isolation. Trade networks, especially the Indian Ocean routes linking the Arab world with East Africa, South Asia, and Southeast Asia, carried not only goods but ideas. Muslim merchants and traders established communities and networks wherever they traded, introducing Islamic practices and beliefs as part of daily life. Religious outreach by missionaries, including Sufi scholars and preachers, often worked within these trading circles and local traditions, presenting Islam in approachable forms that resonated with diverse populations and facilitated conversions. The migration of Muslim communities—settlors, students, artisans—helped solidify religious presence by building mosques, schools, and social networks that supported ongoing practice and cultural exchange. War and conquest also contributed by expanding political influence and governance under Muslim rule, which could create conditions for diffusion through administration and legitimacy, even as everyday contact and exchange usually played the larger role. Together, these intertwined processes explain how Islam diffused widely across Africa and Asia and into other parts of the Eastern Hemisphere.
