Explanation:
There have been many reasons that led to the fall of the Ancient World of Egypt, but perhaps the most significant issue was the weakening of the Prophet's legitimacy and the aristocracy and priesthood's resulting increasing strength. This resulted to Egypt's decentralization of authority and endless wars for authority and civil conflict.
The reasons that contributed to imperial Egypt's collapse were highly unpredictable. The Egyptian army was defeated by a civil war combined with incursions by the Armenians, enabling the Persian empire to conquer Egypt effectively and take control.
Around 2200 BC and 2150 BC, an extreme drought came which disrupted the regular irrigation of the Nile and culminated in the Old Country's decline and collapse, accompanied by generations of famine and warfare.
