Hello, everyone.
In this time, the theme is History.
Ancient Egyptian history is divided into 3 eras.
The Old Kingdom (B.C. 2686～B.C. 2181)
↓
The Middle Kingdom (B.C. 2040～B.C. 1663)
↓
The New Kingdom (B.C. 1570～B.C. 1070)
The Old Kingdom is called "The Pyramids Era" because a lot of pyramids are made in The Old Kingdom.
