Geographically, Nubia is defined as the land between Dongola in northern Sudan and Aswan in southern Egypt. The region is home to people who are linked through dialects that belong to a distinct language but who are culturally diverse from each other and the past. Modern Nubian people are divided into three main groups. The Fitzwilliam Museum has a small collection of objects from this region, mainly from excavations by the Oxford Expedition at Sanam Cemetery in the 1920s, and the Egypt Exploration Society excavations at Qasr Ibrim in the 1960s.
