Ahmose I. managed to force the Hyksos out of Egypt definitively, unified the Egypt again and stimulated the economy during his 25 years reign. His reign is a start of period called the New Kingdom, period of expansion, when Egypt became a world power.
Ahmose I. should came to the Egyptian throne in 1,550 BC, when his brother Kamose died on battle field during a river campaign against the Hyksos. But he was only a boy then, so the royal mother Ahhotep I. came to the throne as a regent. The fight with the Hyksos was deadlocked then.
War with the Hyksos
Ahmose I. began to fight against the Hyksos approximately in the 11th year of his reign. At first he gained Memphis (Mennefer) and then he also gained the last enemy bastion - their capital Avaris. Then he forced the Hyksos up to Palestina and he broke their resistance definitively, when he destroyed their rear base Sharuhen, which was situated to the south from Gaza. But the fight wasn't easy at all; the siege lasted whole 3 years. Ahmose was encouraged by this success, so he did another campaign, conquered Phoenicia and southern Syria and got to the bank of the Euphrates river as the first Pharaoh.
There was a need to ensure the control over middle Egypt and conquer Nubia again after forcing the Hyksos out of Egypt. Ahmose succeeded in it after three campaigns. Ahmose I. wanted to highlight his dominance over the Kingdom Kush, so he placed the most significant Egyptian administrative center in Buhen and let build the first temple of the New Kingdom period to the south from the city in Sai.
Thebes (Waset) stayed the capital under Ahmose rule and he supported the Amun-Ra cult and under the standard of it unified the country at the expense of the Middle and Lower Egypt deities.
Ahmose I. reorganized the temples administration, took control over the corn market and Egyptian economy was recovered significantly thanks to him, especially because of the number of buildings he built all over the land - in Karnak, Abydos, Buhen, El-Amra, Memphis (Mennefer) and other places. He reopened mines and quarries, because there was a need to cover increased demand for building materials.
Several significant dignitaries lived under Ahmose I. rule - the most famous was Ahmose, son of Ebana. He was a namesake of the Pharaoh, who was in command of a royal ship at early age. He also was in all great battles with Ahmose I. and always excelled in courage and heroism. Ahmose served to Amenhotep I. and Thutmose I. as well. It was under Thutmose I. rule, when Ahmose - despite his advanced age - led a campaign into Sudan and Anatolia.
Adored women of Ahmose
Ahmose I. was ardently celebrated and by the Egyptians and he was worshipped even long time after his death (he died approximately in 1,518 BC). Ahmose was buried in Dra' Abu el-Naga', but his mortuary cult was kept in Abydos.
Except the ruler also his grandmother Tetisheri and his mother Ahhotep I. (daughter of Tao I.) were worshipped there. Ahhotep took part in the reign of her husband Tao II. Seqenenre and she ruled herself as a regent at the time of Ahmose youth.
Also Ahmose's wife Ahmose-Nefertari took part actively in the reign. When her husband was at war, she was always in the lead of the land. After his death she ruled as a regent instead of son Amenhotep I. Later Ahmose-Nefertari became the first God's wife of Amun.
