missionaries

n. person sent on a mission; person sent out from a religious organization to proselytize and/or offer humanitarian aid in a foreign or untouched region; one who has strong opinions or principles and tries to convert others to his position

A missionary is a member of a religion who works to convert those who do not share the missionary's faith; someone who proselytizes. Judaism, Mandaeism, Hinduism, Parsees, Shinto and faiths focused on ancestor cult or local spirits make little or no effort to convert those who do not share their beliefs, but many religious groups engage in missionary activities.
