Animal Farm entertains and enriches readers of all ages exposing the risks that lie at the heart of every revolution. A powerful tool to understand the psychological mechanisms leading to the rise of a dictatorship, from propaganda to the cult of the leader and the exploitation of real or supposed enemies to create unity and consent. Better than any political analysis, it helps us understand what happened in Europe not too many decades ago while entertaining us with irony. This edition is specially tailored to the needs of English learners and contains the original text with numerous explanatory notes, an introduction, the keywords to understand the main ideas, several activities, a list of the most important historical references and an essay on totalitarianism by Orwell.
