In Shakespeare’s A Midsummer Night’s Dream, the royal fairy married to Titania is Oberon.
Oberon is the King of the Fairies, while Titania is the Fairy Queen. Their relationship drives one of the play’s central supernatural plots: they quarrel over an Indian changeling boy whom Oberon wants to take into his service. Titania refuses, and their dispute is presented as powerful enough to disturb the natural world, causing storms, floods, and failed crops.
Oberon retaliates with a magical flower whose juice makes a sleeping person fall in love with the first living thing they see. Titania awakens and falls in love with Bottom, an Athenian craftsman whose head Puck has transformed into a donkey’s. This comic episode is often why Bottom is mistakenly remembered as Titania’s partner, but the enchantment is temporary.
By the end of the play, Oberon reverses the spell and reunites with Titania. Theseus is the Duke of Athens, Puck is Oberon’s mischievous servant, and Bottom is one of the human “mechanicals”—not a member of the fairy royal family.
