Seifert published his first book of poetry, City of Tears, in 1921 and in the next several decades went through several phases of development. He wrote in an unaffected, down-to-earth style about the everyday concerns and emotions of common people. His early works reflected his interest in the Russian Revolution, dadaism, and surrealism. Later, he rejected Soviet communism and wrote poetry that protested the conquest of his homeland. Married in 1928, Seifert had two children. Throughout the latter part of his life, he lived quietly in a Prague suburb until his death from a heart ailment in 1986.
