The emergence of the Hyksos poses one of the greatest dilemmas of Egyptian history. Its origin, meaning and permanence are still the object of study and research. If it began as a gradual migration, it was transformed over time into military conquest of Egyptian territory. This was achieved by the technological advances that gave the foreign invaders tactical advantages that were decisive; namely: the introduction of the compound bow, the bronze scale armor, the daggers and curved bronze swords, the use of the horse and chariots (at the end of his reign), unknown by the Egyptians, and the intensive use of the bronze that gave the Hyksos a decisive military advantage.
