What is the title of the poem associated with the date "September 1, 1939"?

The poem associated with the date "September 1, 1939," is indeed "The Unknown Citizen." This poem by W.H. Auden was written in response to the changing social and political landscape of the time, particularly reflecting on the ideas of conformity and the individual’s place within society. The title references a nameless individual who is portrayed as a model citizen, praised for his compliance to societal norms.

"September 1, 1939," marks the beginning of World War II, a significant historical event that inspired Auden to reflect on themes of existence, identity, and the nature of modern society in his work.
