The first thing to untangle is the title. Kim Il Sung remains the “Eternal President.” Kim Jong Il and Kim Jong Un did not inherit that office. The family succession happened through different Party and state posts.

Formally, the DPRK still describes a democratic-centralist system. The Constitution says that the Workers’ Party leads all state activity, that elected assemblies exercise state power, and that the Supreme People’s Assembly elects or recalls the head of the State Affairs Commission. In the official theory, the leader, Party, and masses are not competing centres. They form one political organism, with the leader giving unity to the Party’s line.

That is also where the contradiction sits. A leadership selected repeatedly from one family can pass through formally collective institutions while narrowing their real freedom to choose. A communist critique in this corpus argues that historical gaps between Party congresses and the doctrine of loyalty to the leader weakened the democratic side of democratic centralism. The available documents can map the formal machinery and the competing theories. They cannot show how much internal disagreement or choice existed behind closed doors.
