King Coal

Upton Sinclair is one of the not too many writers who have consecrated their lives to the agitation for social justice, and who have also enrolled their art in the service of a set purpose. A great and non-temporizing enthusiast, he never flinched from making sacrifices. Now and then he attained great material successes as a writer, but invariably he invested and lost his earnings in enterprises by which he had hoped to ward off injustice and to further human happiness. **King Coal** is a 1917 novel by Upton Sinclair that describes the poor working conditions in the coal mining industry in the western United States during the 1910s, from the perspective of a single protagonist, Hal Warner. As in his earlier work, The Jungle, Sinclair uses the novel to express his socialist viewpoint. The book is based on the 1913-1914 Colorado coal strikes and written just after the Ludlow massacre. The sequel to *King Coal* was posthumously published under the title, *The Coal War*. (Source: [Wikipedia](https://en.wikipedia.org/wiki/King_Coal))
