Julia Ward Howe, "The Battle Hymn of the Republic"
The Grapes of Wrath, novel by John Steinbeck, published in 1939. Set during the Great Depression, it traces the migration of an Oklahoma Dust Bowl family to California and their subsequent hardships as migrant farm workers. It won a Pulitzer Prize in 1940. The work did much to publicize the injustices of migrant labour.
The narrative, interrupted by prose-poem interludes, chronicles the struggles of the Joad family on a failing Oklahoma farm, their difficult journey to California, and their disillusionment once they arrive there and fall prey to a parasitic economic system. The insularity of the Joads—Ma’s obsession with family togetherness, son Tom’s self-centredness, and daughter Rose of Sharon’s materialism—ultimately gives way to a sense of universal community.
