Thutmose III acceded to the throne, but for much of his early reign political power was exercised in a co-regency arrangement with Hatshepsut—shaping the conditions under which his later military expansion became possible.
Hatshepsut ruled as pharaoh during the earlier decades of Thutmose III’s reign; standard chronologies place her reign within his, helping explain why major Asiatic campaigning is concentrated after she is no longer active.
After Hatshepsut’s death, Thutmose III ruled without a senior co-regent; Egyptian sources connect the ensuing Levantine revolt with this political transition.
The Annals of Thutmose III at Karnak compile campaign records in Syro-Palestine across regnal years 22–42, documenting routes, plunder, and tribute mechanisms central to Egyptian hegemony.
In his first major Levantine campaign, Thutmose III marched from the Egyptian frontier into Canaan and fought the coalition led by the ruler of Kadesh at Megiddo—an early, unusually detailed battle narrative preserved in the Karnak annals.
Following the battlefield victory, Megiddo was besieged for months before surrender; this outcome reasserted Egyptian control over Canaan and provided a base for subsequent northern campaigns.
Subsequent expeditions focused on suppressing renewed resistance and locking in administration through garrisons and the extraction of tribute—shifting from one-off raiding toward sustained imperial management.
In regnal year 29, Thutmose III’s operations moved deeper into Syria; sources describe the taking of towns and the establishment of garrisons in Djahy (often associated with southern Syria), supporting a more permanent Egyptian presence.
In regnal year 30, Egyptian forces advanced again toward the Orontes region; accounts emphasize systematic devastation and pressure on Kadesh, a focal node in anti-Egyptian coalitions.
In regnal year 31, Thutmose III continued campaigning in coastal and inland Syria, part of a sustained effort to neutralize Kadesh’s influence and secure the logistical corridor for future northern offensives.
In regnal year 33, Thutmose III transported boats to the north, crossed the Euphrates, and struck into Mitannian territory—an iconic moment in projecting Egyptian power into northern Syria/Upper Mesopotamia.
The annals’ coverage through regnal year 42 reflects a prolonged cycle of campaigning to deter rebellion, reimpose tribute, and stabilize Egypt’s sphere of influence across the Levant.
Thutmose III died after a long reign; by this point Egypt’s New Kingdom empire had reached a high-water mark in the Levant, with established practices of garrisoning, hostages/education of vassal elites, and tribute extraction continuing under successors.
