The term “enmity” has been employed in literature to evoke a broad spectrum of hostilities, from the fierce and public to the quietly personal. In historical and political contexts—such as in Strabo’s account of Athenian hostilities [1] and Thucydides’ description of ancient quarrels [2]—it denotes deep-seated, often institutional conflict, emphasizing its role in shaping cultural and geopolitical destinies. Equally, in more intimate narratives, authors like Shakespeare [3] and Dumas [4] employ “enmity” to illustrate personal and familial strife, where bitter feuds and inherited grudges complicate relationships and obstruct happiness. Meanwhile, philosophers and essayists from Cicero [5] to Nietzsche [6] have used the term to reflect on the darker aspects of human nature, suggesting that enmity may arise from or lead to internal discord, moral dilemmas, and even societal imbalance. This diversity of usage, seen also in the works of Emerson [7] and Hardy [8, 9], underscores the adaptability of “enmity” as a literary motif—one that can articulate both the calamities of external conflict and the subtleties of internal, personal opposition.
