The Norrmalmstorg robbery -

The phrase "Stockholm syndrome" was coined by criminologist and psychologist Nils Bejerot. It originated with the Norrmalmstorg bank robbery, which took place in Stockholm, Sweden, on August 23, 1973.

Jan-Erik Olsson, a 32-year-old convict, attempted to rob Sveriges Kreditbank in Norrmalmstorg square. He took four hostages (pictured): Birgitta Lundblad, Elisabeth Oldgren, Kristin Ehnmark, and Sven Säfström.

The four hostages were held captive in a bank vault for six days, but it quickly became evident that they were bonding with Olsson (pictured) and Olofsson. During a phone call with Prime Minister Olof Palme, Kristin Ehnmark, who reportedly developed the closest bond with Olsson, expressed her disappointment that the robbers' demands weren't being met. She even said that she fully trusted them.

After the crime, both Olsson and Olofsson (pictured standing) were charged and convicted, but Olofsson’s charges were ultimately dropped due to claims that he was only there to save the hostages. The victims raised money for their court fees, and even refused to testify against them.

The case of 19-year-old Patty Hearst, the granddaughter of publisher William Randolph Hearst, is one of the most famous examples of Stockholm syndrome.

Mackenzie Phillips -

One of the most shocking cases of Stockholm syndrome is that of actress Mackenzie Phillips, daughter of John Phillips from The Mamas and The Papas. In her 2009 memoir 'High on Arrival,' she revealed that she passed out after a drug binge at the age of 19, and woke up to find her father sexually assaulting her. She proceeded to have a consensual, drug-fueled relationship with him for the next decade.

Her acceptance of the relationship ended when John Phillips began talking about moving to Fiji with his other children and living with her as his wife.

However, the relationship continued until she became pregnant, and her father arranged to have the pregnancy terminated. After that, she finally found the strength to stop the abuse.
