This book is an excellent read! It provides a well-organized and concise summary of Ethiopia’s entire history, which is no small task given the country’s rich and complex past. The writing is consistent, informative, and historically accurate, making it easy to follow and deeply engaging. I especially appreciate how it also includes insights into Eritrea’s history, offering a broader understanding of the region. I highly recommend this book to anyone seeking a solid, accessible introduction to Ethiopian and Eritrean history. Captivating History did a fantastic job!

A compact history
Format: Paperback
Sometimes we want to take a historical subject that we know little about and get a brief gloss to learn enough to discover which parts of the subject we want to delve into at greater length. "History of Ethiopia" is exactly what we need to satisfy that desire.
We get the entire history of the African nation, from the very ancient days up to this very year, 2022. naturally, we do not get many nuances. What we do get is the big picture. We know how the various periods in history fit together. From the Queen of Sheba to the nasty era of the Communist Derg, we get a little bit of everything.
One irritation that I had was the coverage of the Ethiopian-Somalia war in the 1970s. The crucial role played by the Cuban army is committed entirely. On the other hand, the 1540 Portuguese expedition headed by Christopher da Gama is briefly but adequately covered. Save for the intervention of da Gama the kingdom might well have been lost.
If you need a fast introduction to Ethiopia, this is a good place to begin. Captivating History, the maker, has dozens of similar books, often on specific, narrowly focuses topics.

Ethiopia from the time when the Queen of Sheba ruled
Format: Kindle
Ethiopia has a long rich history that Captivating History managed to cover in 100 pages. This book starts out by letting us know that Ethiopia is one of the first places humans settled in. One of the first kingdoms in Ethiopia was the Kingdom of Aksum. Like most African countries, Aksum established trade routes and had the silk road running through their kingdom.
The Queen of Sheba is a controversial historical leader. Many scholars believe she was queen in Ethiopia. The bible states that a queen of the south came to Israel to meet King Solomon. Historians believe that the queen of the south was in fact the Queen of Sheba. While the queen was there her and King Solomon became very close and when the Queen of Sheba returned to Ethiopia she had King Solomon's baby. Menelik I may have been King Solomon's son. Some believe that when Menelik I when to visit his father, King Solomon, Menelik returned to Ethiopia with the Ark of the Covenant. Some believe that the ark is hidden away in some Ethiopian monastery, still today.
There is still a lot of Ethiopia's history left for you to learn about by reading this book.
