Differentiated book- It has a historical context with research of the time-The Iron Heel is a Jack London novel published in 1908. It can be considered more or less interchangeably as a dystopia (or negative utopia), a uchronia, science fiction. "The Iron Heel" is the name given by the revolutionary worker Ernest Everhard to the government that the Industrial Oligarchy built in the 20th century. In history at the end of the 19th century, the large industrial corporations have been creating monopolies in strategic industries (the post, the railways, etc.), until they became a kind of superior and impenetrable social class, well protected by their control of the Government, the police, the army and the courts of law. In this context, the workers try to organize themselves to take political action against the Senate. In response, the Iron Heel prepares a fraudulent attack in the United States Congress.Through which they can initiate vigorous repression, and practically abolish democracy. The workers organize for a vigorous resistance, in the form of a systematic worldwide strike, which paralyzes all services, including communications, and thus leaves the oligarchs defenseless. These, in response, create squads of Mercenaries that work as paramilitary forces, and that are dedicated to subduing the peasant and rebel workers.
