The Party in George Orwell's novel "1984" is different from other oligarchies of the past because it maintains power through a combination of technological surveillance and mind control. The Party uses telescreens and the Thought Police to monitor the thoughts and actions of its citizens, and it manipulates language and history to control people's beliefs and perceptions. Unlike other oligarchies, which might use force or propaganda to maintain control, the Party's power is based on its ability to manipulate people's minds and create a sense of psychological isolation and dependence.
