Long-lasting, bitter quarrels or conflicts between individuals, families, or groups, often marked by acts of revenge.
From Old French faide (feud, vendetta), from Germanic fehde (enmity). The word became associated with Mediterranean and highland cultures' revenge cycles.
The most famous American feud was between the Hatfields and McCoys (1880s-1890s), which killed at least 13 people and became a cultural metaphor for pointless cycles of retaliation that destroy communities.
