In A Midsummer Night’s Dream, Oberon is the fairy king. Shakespeare presents him as a powerful supernatural ruler who is married to Titania, the fairy queen. Their quarrel over a young changeling boy drives much of the play’s magical disorder.
Oberon’s conflict with Titania affects the natural world: the weather becomes unusually disturbed, and the seasons seem out of balance. To force her to surrender the child, Oberon uses a magical flower whose juice makes a sleeping person fall in love with the first living creature seen after waking. The enchantment causes Titania to adore Bottom, a weaver whose head Puck has transformed into that of an ass.
Several answer choices are easy to mix up. Titania is the queen, not the king; Puck is Oberon’s mischievous servant and agent; and Theseus is the Duke of Athens, a human ruler whose wedding frames the play. Oberon’s name also predates Shakespeare: he appears as a fairy king in earlier medieval and Renaissance literature, though Shakespeare made the character especially famous.
