( /ˌkʊblə ˈkɑːn/) is a poem written by Samuel Taylor Coleridge, completed in 1797 and published in 1816. According to Coleridge's Preface to Kubla Khan
, the poem was composed one night after he experienced an opium influenced dream after reading a work describing Xanadu, the summer palace of the Mongol ruler and Emperor of China Kublai Khan. Upon waking, he set about writing lines of poetry that came to him from the dream until he was interrupted by a person from Porlock. The poem could not be completed according to its original 200–300 line plan as the interruption caused him to forget the lines. He left it unpublished and kept it for private readings for his friends until 1816 when, on the prompting by George Gordon Byron, it was published.
Some of Coleridge's contemporaries denounced the poem and questioned his story about its origin. It was not until years later that critics began to openly admire the poem. Most modern critics now view Kubla Khan as one of Coleridge's three great poems, with The Rime of the Ancient Mariner and Christabel. The poem is considered one of the most famous examples of Romanticism in English poetry. A copy of the manuscript is a permanent exhibit at the British Museum in London.
