1984 is a dystopian social science fiction novel and cautionary tale.Thematically, it centres on the consequences of totalitarianism, mass surveillance and repressive regimentation of people and behaviours within society. Orwell, a democratic socialist, modelled the totalitarian government in the novel after Stalinist Russia and Nazi Germany. More broadly, the novel examines the role of truth and facts within politics and the ways in which they are manipulated.

The story takes place in an imagined future, the year 1984, when much of the world has fallen victim to perpetual war, omnipresent government surveillance, historical negationism, and propaganda. Great Britain, known as Airstrip One, has become a province of the totalitarian superstate Oceania, ruled by the Party, who employ the Thought Police to persecute individuality and independent thinking. Big Brother, the dictatorial leader of Oceania, enjoys an intense cult of personality, manufactured by the party`s excessive brainwashing techniques. The protagonist, Winston Smith, is a diligent and skillful rank-and-file worker and Outer Party member who secretly hates the Party and dreams of rebellion. He enters into a forbidden relationship with his colleague Julia and starts to remember what life was like before the Party came to power.
