Thutmose I (sometimes read as Thutmosis or Tuthmosis I, Thothmes in older history works in Latinized Greek; meaning "Thoth is born") was the third pharaoh of the 18th Dynasty of Egypt.

Thutmose never called himself "Son of the King", hence is believed to be born in non-royal family, to woman named Senseneb and an unknown father.

[11] A heliacal rising of Sothis was recorded in the reign of Thutmose's predecessor, Amenhotep I, which has been dated to 1517 BC, assuming the observation was made at Thebes.

[14] This data is supported by two dated inscriptions from Years 8 and 9 of his reign bearing his cartouche found inscribed on a stone block in Karnak.

According to the tomb autobiography of Ahmose, son of Ebana, Thutmose traveled up the Nile and fought in the battle, personally killing the Nubian king.

His Majesty commanded to dig this canal after he found it stopped up with stones [so that] no [ship sailed upon it]; Year 3, first month of the third season, day 22.

[22] Many Levantine sites were destroyed in the middle of the 16th century B.C., and these destructions have often been attributed to the military campaigns of Thutmose I, or of his predecessor Amenhotep I.

[21] He inscribed a large tableau on the Hagar el-Merwa, a quartz outcrop c. 40m long and 50m wide 1200 meters from the Nile, on top of several local inscriptions.

"[31] The location of KV20, if not its original owner, had been known since the Napoleonic expedition of 1799 and, in 1844, the Prussian scholar Karl Richard Lepsius had partially explored its upper passage,[32] but all its passageways "had become blocked by a solidified mass of rubble, small stones and rubbish which had been carried into the tomb by floodwaters" and only during the 1903–04 excavation season did Howard Carter, after two previous seasons of strenuous work, clear its corridors and enter its double burial chamber.

[32] Here, among the debris of broken pottery and shattered stone vessels from the burial chamber and lower passages, were the remnants of two vases made for Queen Ahmose Nefertari, which formed part of Thutmose I's original funerary equipment; one of the vases contained a secondary inscription that says that Thutmose II made it "as his monument to his father.

Hatshepsut's beautifully carved sarcophagus "was discovered open with no sign of a body, and with the lid lying discarded on the floor"; it is now housed in the Cairo Museum along with a matching yellow quartzite canopic chest.

[34] A second sarcophagus was found lying on its side with its almost undamaged lid propped against the wall nearby; it was eventually presented to Theodore M. Davis, the excavation's financial sponsor, as a gesture of appreciation for his support.

She made it as her monument to her father whom she loved, the Good God, Lord of the Two Lands, Aakheperkare, the son of Re, Thutmosis the justified.

[36] Unfortunately, Thutmose I's remains were disturbed late during the 20th dynasty when KV38 was plundered; the sarcophagus's lid was broken and all this king's valuable precious jewelry and grave goods were stolen.

[38] This identification has been supported by subsequent examinations, revealing that the embalming techniques used came from the appropriate period of time, almost certainly after that of Ahmose I and made during the 18th dynasty.

[39] Gaston Maspero described the mummy as follows: The king was already advanced in age at the time of his death, being over fifty years old, to judge by the incisor teeth, which are worn and corroded by the impurities of which the Egyptian bread was full.

The body, though small and emaciated, shows evidence of unusual muscular strength; the head is bald, the features are refined, and the mouth still bears an expression characteristic of shrewdness and cunning.

[38]James Harris and Fawzia Hussien (1991) conducted an X-ray survey on New Kingdom royal mummies and examined Thutmose I's mummified remains.

The study indicated that the mummy belonged to haplogroup L, which is mainly observed in southern, western and central Asia (highest in the Indian subcontinent).

But in 2007, Hawass announced that the mummy previously thought to be Thutmose I is that of a 30-year-old man who died as a result of an arrow wound to the chest.

[43] In April 2021 the mummy was moved to the National Museum of Egyptian Civilization along with those of 17 kings and four queens in an event termed the Pharaohs' Golden Parade.
