Propaganda is a central theme in George Orwell's 1984, where the Party uses it as a tool for psychological manipulation and control. The Party's slogans, constant surveillance, and manipulation of truth serve to maintain its power and suppress dissent. The novel illustrates how propaganda can distort reality and control the populace's thoughts and beliefs.

The Party's slogan, "War is Peace, Freedom is Slavery, Ignorance is Strength," exemplifies the concept of doublethink, where contradictory beliefs coexist. This slogan is a key element of the Party's propaganda, convincing citizens to accept false realities. The Ministry of Truth, Love, and Peace are all misnomers, as they represent the opposite of their names. This manipulation ensures that the populace accepts the Party's version of reality without question.

Orwell draws parallels between the Party's propaganda and the tactics used by totalitarian regimes like Nazi Germany. Both Oceania and Nazi Germany employ propaganda, surveillance, and scapegoating to control their citizens. The Party uses Emmanuel Goldstein as a scapegoat, similar to how the Nazis used Jews and other groups. Youth organizations like the Junior Spies indoctrinate children with Party ideology, akin to the Hitler Youth.

The novel also highlights the arbitrary nature of war as a tool for propaganda. In Part 2, Chapter 9, Oceania suddenly shifts its enemy from Eurasia to Eastasia, demonstrating how war is used to control the populace. The perpetual state of war distracts citizens and reinforces the Party's power. This manipulation of truth keeps the population compliant and unaware of the Party's true motives.

Hate Week is another example of the Party's use of propaganda to control the masses. The event channels citizens' aggression towards political enemies, creating a hysterical atmosphere. The Party orchestrates parades, speeches, and public executions to maintain control and focus the population's energy on supporting Big Brother. This manipulation of public sentiment ensures the Party's dominance and suppresses any potential rebellion.
