In Greek mythology, Eris (Ancient Greek: Ἔρις, romanized: Eris, lit. 'Strife') is the goddess and personification of strife and discord, particularly in war, and in the Iliad (where she is the "sister" of Ares the god of war). According to Hesiod she was the daughter of primordial Nyx (Night), and the mother of a long list of undesirable personified abstractions, such as Ponos (Toil), Limos (Famine), Algae (Pains) and Ate (Delusion). Eris initiated a quarrel between Hera, Athena and Aphrodite, which led to the Judgement of Paris and ultimately the Trojan War.
