"Heathen" derives from Old English "hǣðen" (dwelling on heaths, uncivilized), referring to those outside Christianity, particularly pagans. Medieval crusade literature extensively employed it for Muslims, while missionaries used it for indigenous peoples. The term carries judgmental weight, positioning Christianity as normative and others as benighted. Poets used "heathen" when depicting religious conflict, missionary activity, or cultural encounter where religious difference mattered. Its appearance often revealed speaker's prejudices and cultural assumptions. The word functioned both descriptively (non-Christian) and pejoratively (savage, uncivilized), this slippage reflecting historical attitudes conflating religious and cultural difference. Later poets aware of this history could exploit "heathen" ironically or critically, exposing religious prejudice. The term's charged nature made it valuable for exploring themes of faith, otherness, tolerance, and the violence done through religious categorization and judgment.

Heathen appears throughout literature as religious and cultural other, carrying implications of paganism, irreligion, and cultural difference. Medieval and Renaissance texts use it for non-Christians, especially Muslims and classical pagans. The term combines religious and cultural othering, often with implied inferiority. Related to "pagan" but more specifically northern European term. Essential for analyzing religious identity construction, orientalism, and how literature creates Christian versus non-Christian boundaries. The term's negative connotations reflect Christian-centered worldview. Useful for discussing religious intolerance in literature, how texts construct legitimate versus illegitimate belief systems, and the relationship between religion and civilization in literary imagination. Modern usage attempts neutrality but term carries historical baggage of Christian supremacy.
