The Oceanian province of Airstrip One (formerly known as Great Britain) is a world of perpetual war, omnipresent government surveillance, and public mind control, dictated by a political system euphemistically named English Socialism under the control of a privileged Inner Party elite that persecutes all individualism and independent thinking as thoughtcrimes. Their tyranny is headed by Big Brother, the quasi-divine Party leader who enjoys an intense cult of personality, but who may not even exist. Big Brother and the Party justify their rule in the name of a supposed greater good. The protagonist of the novel, Winston Smith, is a member of the Outer Party who works for the Ministry of Truth (Minitrue), which is responsible for propaganda and historical revisionism. His job is to re-write past newspaper articles so that the historical record always supports the current party line. Smith is a diligent and skillful worker, but he secretly hates the Party and dreams of rebellion against Big Brother.
