Patty Hearst (#6) was ransomed for $6 million in 1974.
You hear in movies how authorities "don't negotiate with kidnappers," but the truth is that ransoms often get paid. We've ranked the biggest ransoms of the modern era (adjusted for inflation).
Wealthy heirs, wealthy businessmen, and oil tankers have all been targeted. An incredible number of these cases came during a few years in the early 70s, especially in Argentina.
This list is missing cases where the ransom was not made public. It also leaves off pre-modern ransoms, including literal king's ransoms, due to limits of available records.
