Ancient Egypt was a civilization in Upper east Africa arranged in the Nile Valley. Ancient Egyptian civilization followed ancient Egypt and blended around 3100BC (as per ordinary Egyptian order) with the political unification of Upper and Lower Egypt under Menes (frequently related to Narmer). The historical backdrop of ancient Egypt happened as a progression of stable kingdoms, isolated by times of relative flimsiness known as Transitional Periods: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age and the New Kingdom of the Late Bronze Age.
