Analyze why upper Egypt can defeat lower Egypt.

In ancient Egypt, many villages and communities united to form a "country". The original reason may be to facilitate the construction of water conservancy irrigation system. Each state has its own totem and state god, and the army appears, and the state becomes an independent small country. Due to the long-term war and merger among the states, two independent kingdoms-Upper Egypt (Nile Valley) and Lower Egypt (Nile Delta) were formed in 4000 BC. Due to different natural environments, upper Egypt and lower Egypt formed different cultures and beliefs. Since ancient times, Egyptians and neighboring nationalities have called Egypt "two places".

In the Upper Egypt-Nile Valley, cliffs are visible, and the desert is further away. Advocate white, the king wears a white crown, and the treasury calls it the White House. Worship the vulture god Nekhbet nabek, symbolized by the lotus flower.

Lower Egypt-the flat and endless Nile Delta. Lower Egypt advocates red, the king wears a red crown, and the Ministry of Finance calls it the Red Room. Wadjet, the cobra god who worships the symbol of papyrus.

Unification of Upper and Lower Egypt:

The culture of Lower Egypt developed rapidly, and papyrus first appeared. However, due to the impassable swamps in the delta region, the States have great independence and the king is not easy to control, so they are not as powerful as upper Egypt politically and militarily.

There are frequent wars in upper and lower Egypt. Around 3 100 BC, King menes of Upper Egypt launched a large-scale war to conquer Lower Egypt. The tragic scene of the war and the epic heroic deeds during the war were lost in the long history of 5,000 years, but the result was recorded in history forever. Menes conquered the kingdom of Lower Egypt and became the first monarch to win the title of "King of Upper and Lower Egypt".

In order to consolidate the rule of Lower Egypt, menes established a fortress city-Baicheng at the junction of the valley and the delta, that is, the junction of Upper Egypt and Lower Egypt, which was later called Memphis by the Greeks. The site is now near Cairo. Menes also built a long dam to prevent the Nile from flooding. The main purpose of building this city is to strengthen the control of Lower Egypt and prevent the counterattack from the Delta.

The reunification of Egypt is of great significance in history, which makes the Egyptian people less devastated by war, strengthens the overall economic and cultural exchanges in Egypt, and at the same time makes Egypt gradually form a relatively perfect and stable national system. At this time, Egypt already had the basic characteristics of civilization, not only full-time administrative officials, soldiers, religious leaders and artists, but also writing.
