"Grapes of Wrath", is a novel written by John Steinbeck and it was published in 1939. This is the best-known and most popular story written by the author and it won a Pulitzer Prize in 1940. "Grapes of Wrath" tells the story of a family from the Dust Bowl in Oklahoma who hit by the Great Depression, are forced to leave their homes to seek a better future in California. Along the way, this family faces many adventures and also many hardships and most importantly, they face the effects of poverty and lack of opportunity that has affected an entire country. One of the main purposes of Steinbeck while writing "Grapes of Wrath", aside from showing the obvious devastation called by the Dust Bowl and the Great Depression, especially in Oklahoma, was to criticize the way that the lands had been used to generate profit, instead of thinking about policies to keep the people fed. In order for him to be able to portray the struggles faced in "Grapes of Wrath", one thing that Steinbeck did was visit migrants camps and share time in the small populations and establishments created by migrants in tents. There, he came face to face with the horrors being lived by these people and that was the fodder he used to write this great novel.
