Mass grave

A mass grave is a grave containing multiple human corpses, which may or may not be identified prior to burial. Although mass graves can be used during major conflicts, in modern times they are more usually seen after events such as a major famine, epidemic, or natural disaster.

Mass graves are a variation on common burial, still occasionally practiced today under normal circumstances. Mass or communal burial was a common practice before the development of a dependable crematory chamber by Ludovico Brunetti in 1873.

In Paris, the practice of mass burial, and in particular, the condition of the Cimetière des Innocents, led Louis XVI to eliminate Parisian cemeteries. The remains were removed and placed in the Paris underground forming the early Catacombs. La Cimetière des Innocents alone had 6,000,000 dead to remove. Burial commenced outside the city limits in what is now Père Lachaise Cemetery.

Mass graves are usually created after a large number of people die or are killed, and there is a desire to bury the corpses quickly for sanitation concerns. In disasters, mass graves are used for infection and disease control. In such cases, there is often a breakdown of the social infrastructure that would enable proper identification and disposal of individual bodies.

The debate surrounding mass graves amongst epidemiologists includes whether or not, in a natural disaster, to leave corpses for traditional individual burials, or to bury corpses in mass graves. For example, if an epidemic occurs during winter, flies are less likely to infest corpses, reducing the risk of outbreaks of dysentery, diarrhea, diphtheria, or tetanus, so the use of mass graves is less important. Recent research indicates that the health risks from dead bodies after natural disasters are relatively limited.
