Bog bodies have fascinated scientists and the public alike for decades.
The preserved corpses – naturally mummified in a peat bog – offer a snapshot of life as far back as thousands of years ago.
Now, new analysis reveals the majority of these individuals met a ‘gruesome’ end before being intentionally discarded into the wet, spongy bogland.
An international team of archaeologists examined over 1,000 individuals from 266 sites across Europe.

While some bog bodies are famous for being extremely well-preserved – such as Lindow Man, who was found in a peat bog in Cheshire – these are only a fraction of what has been found.
The researchers also analysed bog skeleton and the partial remains of bones, skin, soft tissue and hair.
Dr Roy van Beek, from Wageningen University in the Netherlands, said: ‘Literally thousands of people have met their end in bogs, only to be found again ages later during peat cutting.
‘The well-preserved examples only tell a small part of this far larger story.’
Examining all types of bog body reveals that they are part of a millennia-long, deep-rooted tradition, the researchers said.
The phenomenon began in southern Scandinavia, around 5000 BC, and gradually spread over Northern Europe.
Where a cause of death could be determined, the majority appear to have met a grisly end – including ritualistic sacrifices, executions and victims of violence.
Causes of death included blows to the head, cutting or stabbing, hanging or strangulation and shooting.
Sources also indicate there were a significant number of accidental deaths in bogs, as well as suicides.
Writing in the journal Antiquity, the team said: ‘Setting aside accidental deaths, the significant evidence for violent deaths and the large number of repeatedly used sites make it safe to assume that most finds of human remains…reflect intentional depositions.’
The researchers also discovered there were bog body ‘hotspots’ – wetlands where the remains of multiple people have been found.
In some cases, these finds reflect a single act such as the mass burial of people who died in battle.
Other bogs were used time and again and the human remains were accompanied by a wide range of other objects, such as animal bones, bronze weapons or ornaments, that are thought to be ritual offerings.
‘All in all, the fascinating new picture that emerges is one of an age-old, diverse and complex phenomenon, that tells multiple stories about major human themes like violence, religion and tragic losses,’ Dr van Beek added.
Lindow Man – the best preserved peat bog body to be found in Britain – still had distinct facial features and even hair and a beard when he was unearthed in 1984.
Examination of the remains revealed he was in his 20s, of average height, was well-built and in good health, and lived around 2,000 years ago.
Closer inspections have shown he suffered from intestinal parasites and his last meal was unleavened bread.
Theories as to how he was killed include blows to the head, garrotting, or a possible stab wound to the neck, before he was placed face-down in the waters of the peat bog.
