Sehertawy Intef I was the first member of his Dynasty to assume a pharaonic title with the Horus name of Sehertawy variously rendered as "Maker of peace in the two lands", "He who has brought calm to the two Lands" and "Pacifier of the two lands". Intef's parents may possibly have been Mentuhotep I and Neferu I. By taking a Horus name with both crowns, Intef declared himself ruler of all Egypt. However, his authority was contested by the other nomarchs of Egypt, chief among them being the 10th Dynasty rulers at Herakleopolis Magna who also laid claim to the title of pharaoh and their powerful ally Ankhtifi, nomarch of Hierakonpolis, and a faithful follower of the Herakleopolitan Dynasty. On his accession to the Theban throne, Intef probably ruled only the Theban nome, but it is conjectured that after defeating Ankhtifi or one of his successors, Intef acquired the three nomes to the south of Thebes, down to Elephantine, and to the north all territories south of the border with the Coptite nome. Alternatively, this may have been achieved by Intef's predecessor Mentuhotep I. Both hypotheses remain conjectural given the paucity of historical records on this period. Intef I got rapidly embroiled in a war with his northern neighbors. A graffito discovered by the Theban Desert Road Survey in the Gebel Tjauti northwest of Thebes reports the presence there of "the assault troops of the son of Ra, Intef". It has been posited that this inscription refers to Intef I whose soldiers were fighting the Coptite nomarch Tjauti. In support of this hypothesis is a nearby worn out stele erected by Tjauti reporting the construction of a road to allow his people to cross the desert "which the ruler of another nome had sealed off fight with my nome...". Although not named explicitly, Darell Baker and other Egyptologists contend that this ruler must either be Intef I or his successor Intef II. In any case, the subsequent defeat of Tjauti ultimately put Koptos, Dendera and the three nomes of Hierakonpolis under Theban control, expanding the Theban kingdom 250 km northward with a border near Abydos.
Tomb
Intef's funerary complex was dug in a hill side at El-Tarif on the opposite bank of the Nile at Thebes and is known today as Saff el-Dawaba. The site of El-Tarif comprises three monumental royal tombs, known as saff tombs. Inscriptions found in one tomb indicate that it belonged to Wahankh Intef II, Intef I's successor. At the opposite, the Saff el-Dawaba is devoid of inscriptions but yielded the earliest type of pottery found at El-Tarif and, for this reason, is most often assigned to Intef I. The Saff el-Dawaba comprises a large sunken courtyard backed by a colonnade leading to a mortuary chapel carved into the hill and flanked by two chambers. The burial chamber of Intef I was dug beneath the mortuary chapel.
