The timeline provided shows the major vents in the history of Ancient Egypt. We can see that Upper and Lower Egypt have unified in 3100 B.C. The ruler who unified the lower and upper Egypt was Menes, who also started the First Dynasty of Egypt.
By the timeline, Middle Kingdom started in 2100 B.C<u>.</u> This period is started with the reunification of Egypt after the Old Kingdom and the age during which Egypt wasn’t as powerful. Mentuhotep II is the one who reunited Egypt and the first pharaoh of the Middle Kingdom.
