Commercial peat cutters discovered a preserved bog body, now known as Lindow Man (head pictured), at Lindow Moss in Cheshire, England.

Peat is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols. Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity.

A bog body is a human cadaver that has been naturally mummified in a peat bog. Such bodies, sometimes known as bog people, are both geographically and chronologically widespread, having been dated between 8000 BC and the Second World War. The common factors of bog bodies are that they have been found in peat and are at least partially preserved. However, the actual levels of preservation vary widely, from immaculately preserved to mere skeletons.

Lindow Man, also known as Lindow II and as Pete Marsh, is the preserved bog body of a man discovered in a peat bog at Lindow Moss near Wilmslow in Cheshire, North West England. The remains were found on 1 August 1984 by commercial peat cutters. Lindow Man is not the only bog body to have been found in the moss; Lindow Woman was discovered the year before, and other body parts have also been recovered. The find was described as "one of the most significant archaeological discoveries of the 1980s" and caused a media sensation. It helped invigorate the study of British bog bodies, which had previously been neglected.

Lindow Moss, also known as Saltersley Common, is a raised mire peat bog on the edge of Wilmslow in Cheshire, England. It has been used as common land since the medieval period and is best known for the discovery of the preserved bog body of Lindow Man in 1984 as well as Lindow Woman the year before.
