Diffusion of Religion and Language
Religion and language spread in genuinely different patterns — and understanding why reveals something real about the difference between a faith that seeks converts and one that doesn't.
Universalizing religions like Christianity and Islam spread across the globe through active proselytism, trade, migration, and historical conquest — all channels this unit has already covered. Ethnic religions like Judaism and Hinduism stay geographically concentrated precisely because they remain tied to a specific people or place and generally don’t seek converts the way universalizing religions do.
Language diffuses through the same historical mechanisms. English became an official language in India and Nigeria because British colonizers relocated there and imposed it — relocation and hierarchical diffusion working through colonial institutions. Long after independence, many former colonies keep the colonizer’s language official, even when most residents speak something else at home — a lasting imprint of that historical diffusion.
Sometimes contact between languages creates something genuinely new. When traders, colonizers, and local populations without a shared language need to communicate, a pidgin can form — simplified, with no native speakers. If that pidgin becomes a community’s actual native language over time, it becomes a creole — a blended, entirely new language distinct from either of its sources. English’s current status as a global lingua franca reflects this same layering: colonial-era diffusion planted it, and contemporary globalization keeps reinforcing its spread today.
