It was not until George Reisner excavated the royal cemeteries at El Kurru and Nuri that archaeological material became available to study the Kushite queenship. Additionally, a few royal tombs of Kushite women have been found at Meroe's cemetery and in Egypt at Abydos (Leahy 1994). At El Kurru, six pyramids belong to royal women of the XXV Dynasty and an pyramid for queen Qalhata of the Napatan period. At Nuri, the tombs of royal women are located on the west plateau with more inscriptional information available at the site, linking the roles that the kings' mothers played in succession and their importance during the Kushite dynasty.
