Lermontov began work on the poem when he was just 14 or 15, but completed it only during his Caucasus exile. Lermontov wrote six major variations of the poem, and the final version was not published until 1842, after his death.
The poem is set in Lermontov's beloved Caucasus Mountains. It opens with the eponymous protagonist wandering the earth, hopeless and troubled. He dwells in infinite isolation, his immortality and unlimited power a worthless burden. Then he espies the beautiful Georgian Princess Tamara, dancing for her wedding, and in the desert of his soul wells an indescribable emotion.
The Demon, acting as a brutal and powerful tyrant, destroys his rival: at his instigation, robbers come to despoil the wedding and kill Tamara's betrothed. The Demon courts Tamara, and Tamara knows fear, yet in him she sees not a demon nor an angel but a tortured soul. Eventually she yields to his embrace, but his kiss is fatal. And though she is taken to Heaven, the Demon is left again "Alone in all the universe, Abandoned, without love or hope!...".
