Eliza Cook's poem "Under the Mistletoe" begins by celebrating the traditional Christmas symbol as a source of warmth, reconciliation, and goodwill, bringing people together. However, the poet quickly expands this idea, questioning why such feelings of peace and love should be confined only to the festive season. She passionately advocates for metaphorically hanging "Love's Mistletoe" everywhere, all year round, urging readers to extend kindness, compassion, and unity to overcome social injustices like oppression, racial prejudice, poverty, and conflict, making love and goodwill universal and perpetual sentiments.
