They are usually personal possessions, supplies to smooth the deceased's journey into the afterlife or offerings to the gods. Grave goods are a type of votive deposit. Most grave goods recovered by archaeologists consist of inorganic objects such as pottery and stone and metal tools but there is evidence that organic objects that have since decayed were also placed in ancient tombs.
Where grave goods appear, grave robbery is a potential problem. Etruscans would scratch the word śuθina, Etruscan for "from a tomb", on grave goods buried with the dead to discourage their reuse by the living. The tomb of pharaoh Tutankhamun is famous because it was one of the few Egyptian tombs that was not thoroughly looted in ancient times.
Grave goods are in origin a sacrifice intended for the benefit of the deceased in the afterlife. Closely related are customs of ancestor worship and offerings to the dead, in modern western culture related to All Souls' Day (Day of the Dead), in East Asia the "hell bank note" and related customs. Also closely related is the custom of retainer sacrifice, where servants or wives of a deceased chieftain are interred with the body. As the inclusion of expensive grave goods and of slaves or retainers became a sign of high status in the Bronze Age, the prohibitive cost led to the development of "fake" grave goods or funerary art, where artwork meant to depict grave goods or retainers is produced for the burial and deposited in the grave in place of the actual sacrifice.
Evidence for intentional burial is found in Neanderthal sites from 130,000 years ago or earlier. In Homo sapiens burials beginning about 100,000 years ago, the body of the deceased was sprinkled with red ochre, and offerings of food, tools, and fresh flowers may have been deposited in the grave.
The distribution of grave goods are a good indicator of the social stratification of a society. Thus, early Neolithic graves tend to show equal distribution of goods, suggesting a more or less classless society, while in Chalcolithic and Bronze Age burials, rich grave goods are concentrated in "chieftain" graves (barrows), indicating social stratification.
The expression of social status in rich graves is taken to extremes in the royal graves of the Bronze Age, notably in Ancient Egypt. The pyramids and the royal graves in the Valley of the Kings are among the most elaborate burials in human history. This trend is continued into the Iron Age. An example of an extremely rich royal grave of the Iron Age is the Terracotta Army of Qin Shi Huang.
In the sphere of the Roman Empire, early Christian graves lack grave goods, and grave goods tend to disappear with the decline of Greco-Roman polytheism in the 5th and 6th centuries. Similarly, the presence of grave goods in the Early Middle Ages in Europe has often been taken as evidence of paganism, although during the period of conversion in Anglo-Saxon England and the Frankish Empire (7th century), the situation may be more complicated. In the Christian Middle Ages, high-status graves are marked on the exterior, with tomb effigies or expensive tomb stones rather than by the presence of grave goods.
The practice of placing grave goods with the dead body has thus an uninterrupted history beginning in the Upper Paleolithic, if not the Middle Paleolithic, upheld until comparatively recent times, in many regions of the world ceasing only with Christianization.
Role in archaeology 
The importance of grave goods in archaeology cannot be overestimated. Because of their almost ubiquitous presence throughout the world and throughout prehistory, in many cases the excavation of every-day items placed in burials is the main source of such artifacts in a given prehistoric culture. However, care must be taken to avoid naive interpretation of grave goods as an objective sample of artefacts in use in a culture. Because of their ritual context, grave goods may represent a special class of artifacts, in some instances produced especially for burial. Artwork produced for the burial itself is known as funerary art, while grave goods in the narrow sense are items produced for actual use that are placed in the grave, but in practice the two categories overlap.
Grave goods in Bronze Age and Iron Age cemeteries are a good indicator of relative social status; in a 2001 study on an Iron Age cemetery in Pontecagnano Faiano, Italy, a correlation was found between the quality of grave goods and Forensic indicators on the skeletons, showing that skeletons in wealthy tombs tended to show substantially less evidence of biological stress during adulthood, with fewer broken bones or signs of hard labor.
