The two kingdoms were the Upper Egypt and the Lower Egypt.
The Egypt is divided into three periods. They are the old kingdom, the middle kingdom and the kingdom.
Upper Egypt and Lower Egypt
Before Menes married the princess of Lower Egypt, the capital of upper Egypt was Heirrakonpolh, and for lower Egypt was Heliopolis. After he unified the two kingdoms, the capital of Egypt became Memphis.
King Narmer
Khufu's kingdom was in the upper Egypt at that time the Egypt was divided into two parts upper Egypt and lower Egypt so Khufu ruled the upper Egypt
The first pharaoh to have united the "two lands" of Upper and Lower Egypt was said to have been King Narmer in 3000 b.c. Thereafter the pharaoh of Egypt was represented wearing a double crown (cat. no. 50a) that combined the white crown of Upper Egypt (cat. no. 26) and the red crown of Lower Egypt (cat. no. 51). Other symbols of the unification of the two lands are combined on the royal regalia: from Lower Egypt, the cobra or uraeus and from Upper Egypt, the vulture.I hope that answered your question!the pharaoh that united Egypt is not called narmer in fact there was no such person that ruled us and they united in 1554 bc and the crown was red and white and i think the phaoroah that united Egypt was called Atem (توم .i hope this gves a btter understanding of the question you asked
Farming communities were formed along the River Nile ca.4000BC. Later two kingdoms were established: Upper Egypt and Lower Egypt. In about 3000BC the two kingdoms were united and Egypt became a kingdom under one pharaoh (king).
Modern Egypt did not become a country through war, but more through a series of revolutions and coups. Ancient Egypt had a long period of dynastic stability followed by a long series of occupations (Persian, Greek, Roman, Arab, and Ottoman).
The Pre-dynastic
The two kingdoms were unified and a new crown was made, the fusion of upper Egypt's crown and lower Egypt's crown.
The two Egyptian kingdoms, Upper and Lower Egypt, arose because the land near the First Cataract and the Nile Delta, respectively, was suitable for agriculture. They united around 3000 B.C.
