Archaeological ethics refers to the moral issues raised through the study of the material past. It is a branch of the Philosophy of archaeology.
In common with other academic disciplines, archaeologists are bound to conduct their investigations to a high standard and observe intellectual property laws, Health and Safety regulations and other legal obligations. Professional bodies in the field require that their members work towards the preservation and management of archaeological resources, treat human remains with dignity and also usually encourage outreach activities. Where these bodies exist, sanctions are in place for those professionals who do not observe these ethical codes. By no means all jurisdictions have such professional bodies however and even where they do exist, membership may not be necessary in order to carry out archaeological investigations. While such considerations are fundamental to a pursuit, they are unfortunately coming rather late to the field. Questions regarding ethics have only arisen since the UNESCO accords in the 1970s began to protect world culture.
A common ethical issue in modern archaeology has been the treatment of human remains found during excavations, especially those that represent the ancestors of aboriginal groups in the New World or the remains of other minority races elsewhere. Where previously sites of great significance to native peoples could be excavated and any burials and artefacts taken to be stored in museums or sold, there is increasing awareness in the West of taking a more respectful approach. The NAGPRA legislation in the United States of America is an example of this. The issue is not limited to ancient remains; nineteenth- and twentieth-century burial sites investigated by archaeologists such as First World War graves and cemeteries disturbed by developments have seen the remains of people with closely connected living relatives being exhumed and taken away.
The international trade in antiquities, although not formally connected with the modern discipline of archaeology has also raised ethical questions regarding the ownership of archaeological artefacts. The market for imported antiquities has encouraged damage to archaeological sites and often led to appeals for the recall.
