Jack London 
The Iron Heel 

The Iron Heel is a dystopian novel by American writer Jack London, first published in 1908. Generally considered to be "the earliest of the modern Dystopian, " it chronicles the rise of an oligarchic tyranny in the United States. It is arguably the novel in which Jack London's socialist views are most explicitly on display. A forerunner of soft science fiction novels and stories of the 1960s and 1970s, the book stresses future changes in society and politics while paying much less attention to technological changes.
