The work was composed on 19 September 1819 and published in 1820 in a volume of Keats's poetry that included Lamia and The Eve of St. Agnes. "To Autumn" is the final work in a group of poems known as Keats's "1819 odes". Although personal problems left him little time to devote to poetry in 1819, he composed "To Autumn" after a walk near Winchester one autumnal evening.
