In George Orwell's 1984, there are four different ministries that function as the different branches of government. They are the Ministry of Truth, the Ministry of Love, the Ministry of Peace, and the Ministry of Plenty.
Despite their harmonious names, the names of each ministry are quite ironic, because they actually function in the complete opposite way from what their names imply.
The Ministry of Truth is where Winston Smith works. Supposedly, Winston and his branch of government are in charge of checking the historical accuracy of things; however, that is not what the Ministry of Truth does. The Ministry of Truth is in charge of Big Brother's propaganda machine. Winston is constantly changing the official records of things, so that they can better reflect the Party's current stance. The Ministry of Truth is in charge of spreading lies.
The Ministry of Love is equally ironic. It's supposed to be in charge of law and order. In some ways it is. The Ministry of Love maintains the thought police and makes sure that nobody even considers thinking a bad thing against Big Brother. But the Ministry of Love's actions are anything but loving. In order to have people follow the rules, the Ministry of Love uses fear mongering and torture to keep citizens in line.
