Why did christianity take hold in some places more than in others?

- Christianity integrated most fully into regions where European colonial powers ruled, where there was an overwhelming European presence, where the established society had been defeated and disrupted, and where no literate world religion was already established.
- It had the least impact when it had to operate with the permission of non-Christian rulers, when it sought to convert in a society that was stable and well established, and when it sought to convert in a region where a literate world religion already existed.
