Proselytism

Proselytism (/ˈprɒsəlɪtɪzəm/) is the policy of attempting to convert people's religious or political beliefs. Carrying out attempts to instill beliefs can be called proselytization.

Sally Sledge discusses religious proselytization as the marketing of religious messages. Proselytism is illegal in some countries. Some draw distinctions between evangelism (or da'wah in Islamic terminology) and proselytism, regarding proselytism as involuntary or coerced; the two terms can also be understood to merely be synonyms.
