King Coal

**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*.
