Английский Этимологический словарь - stockholm syndrome

- 1978, a psychologists' term; the name derives from the Aug. 23, 1973, violent armed robbery of Sveriges Kreditbank in Stockholm, Sweden, after which four bank employees were held hostage in a vault for more than five days. The hostages developed a dramatic attachment to their abuser, and a fear of would-be rescuers, that they could not explain.
