captor

This term carries a heavy connotation of coercion and loss of autonomy, typically appearing in contexts of warfare, kidnapping, or historical accounts of slavery. It emphasizes the power imbalance between the individual in control and the person being held, often implying a state of confinement or forced submission.

While it describes a person, it can also refer to an organization or state entity acting as the jailer. The word is distinct from "kidnapper" in that it focuses on the ongoing state of captivity rather than the initial act of abduction.
