Anneliese Michel
Between 1975 and 1976, she underwent 67 exorcism sessions performed by two priests, conducted over the course of roughly ten months in her family home in Klingenberg, Germany.
Background
Anneliese Michel began experiencing symptoms in her early twenties that doctors were unable to fully diagnose or treat through conventional medical means. As her condition worsened, her family sought the involvement of the Church.
The Sessions
The sessions were conducted under official Church sanction, following a formal request for exorcism. They continued at a regular pace over the following months, documented on audio tape by those present.
Aftermath
The case remains one of the most documented and debated exorcism accounts on record, and continues to be studied by both religious and medical historians today.
