Historical Background
The Man in the Iron Mask remains one of history’s great enigmas. He was imprisoned during the reign of Louis XIV, a time characterized by absolute monarchy and political intrigue. The circumstances surrounding his imprisonment and identity sparked numerous theories and debates among historians and scholars.
In September 1698, he was transferred to the Bastille prison, where he remained until his death on November 19, 1703. The Bastille’s walls, which later became symbolic of tyranny, housed this mysterious figure under the strict guardianship of Bénigne Dauvergne de Saint-Mars. Historical accounts suggest he endured harsh conditions, isolated from the outside world.
The cause of death has led to various theories. Some speculate he succumbed to illness, given the prison’s unsanitary conditions.

Reports indicate that his personal effects were disposed of systematically after his death. His clothes were burned at dawn, and his cell underwent extensive cleaning. Authorities scraped and whitewashed the walls, destroyed all furniture, and eliminated clothing to eradicate any clues about him. This swift action reflects the regime’s desire to maintain secrecy and control the narrative surrounding this figure.
The enduring intrigue surrounding the Man in the Iron Mask invites ongoing research.

The Most Popular Theories
- Eustache Dauger Theory: Many historians consider this one of the most plausible theories. Eustache Dauger, arrested in 1669 on orders from Louis XIV’s minister Louvois, worked as a valet to the treasurer of Cardinal Mazarin. His long imprisonment spanned over 30 years across multiple facilities, including Pignerol and the Bastille. Some experts suggest that he may have faced imprisonment for exposing sensitive details regarding Mazarin’s financial dealings.
- Historical Records: Historical documentation reveals Dauger’s identity linked to various prisons. His lengthy imprisonment aligns with the timeline of the Man in the Iron Mask, leading scholars to advocate for this possibility as credible evidence.
- Contemporaneous Accounts: Accounts from the 17th century mention a mysterious prisoner whose identity was closely guarded. The shared characteristics of this prisoner and existing details about Dauger lend weight to this identity theory.
- Connection to Cardinal Mazarin: The connection between Dauger and Cardinal Mazarin underscores significant implications. If his imprisonment aimed to silence revelations about Mazarin’s dealings, it would explain the severity of his confinement and anonymity.
Multiple theories persist, fostering continuous exploration into the enduring mystery surrounding the Man in the Iron Mask. Historical investigations and archival scrutiny sustain this intrigue, illuminating various facets of his identity.
