The Devils of Martin (Ylöjärvi)

The “Devils of Martin” (Martin Pirut) at Ylöjärvi in southwestern Finland is the earliest poltergeist case in the Finnish historical record for which formal court documentation survives. The case is named after the Martin family farm where the disturbances were principally located, in the rural parish of Ylöjärvi north of Tampere. Activity is documented across the late 1880s with the most intense phase clustered around 1888.

The disturbances followed the standard poltergeist pattern: object movements, percussive sounds inside walls and floors, and disruption of normal farm activity in ways the family could not account for through any mundane source. What distinguishes the Martin case from contemporary Finnish reports is the family’s decision to pursue legal documentation. Affidavits were obtained from family members, farmhands, and neighbouring witnesses, sworn before the local court and entered into the parish register. The decision to seek legal documentation appears to have been driven both by the family’s own conviction that the phenomena were real and by social pressure — neighbours had begun to question whether the family was deliberately staging the events for some unstated reason.

The sworn affidavits described object movements in front of multiple witnesses simultaneously, sounds for which no source could be identified, and at least one episode of physical interference with farm animals. The court documents do not adjudicate the cause of the phenomena; Finnish parish courts of the period had no jurisdiction over the supernatural and the legal purpose of the affidavits was to establish that the witnesses had observed what they claimed to have observed. The documents establish the testimony but do not resolve its explanation.

The Martin case has been used in subsequent Finnish parapsychological literature as a baseline reference for nineteenth-century Finnish poltergeist activity. The case predates the Mäkkylä Ghost of 1946 by roughly six decades and is part of the Finnish-language poltergeist canon. The court documents are preserved in the Ylöjärvi parish archives and the Tampere regional state archive.

The case is also a useful reminder of the geographic and linguistic limits of the standard English-language paranormal canon. Finland produced sustained poltergeist activity through the eighteenth, nineteenth, and twentieth centuries, much of it preserved in Finnish-language records and parish documents that have not been translated. The Martin case is among the better-known to non-Finnish researchers; many of the smaller documented cases remain accessible only to readers of Finnish.
