Who was the Greek goddess of strife and discord?

Eris is the Greek goddess of strife and discord. Her name is the equivalent of Latin Discordia, which means "discord". Eris's Greek opposite is Harmonia, whose Latin counterpart is Concordia. Homer equated her with the war-goddess Enyo, whose Roman counterpart is Bellona. The dwarf planet Eris is named after the goddess.

The classic fairy tale Sleeping Beauty is partly inspired by Eris's role in the wedding of Peleus and Thetis. Like Eris, a malevolent fairy curses a princess after not being invited to the princess's christening.
