The Roman Empire. The Empire of Alexander the Great. The ancient Egyptians. These fallen civilisations are a fundamental part of our history, and they live in on our consciousness. But not all empires have attained such immortality. Some of the greatest of human civilisations are almost forgotten, whether it be our simple localised view of history, or a worldwide amnesia at work. Here I try to uncover the story of a few of them.

1. The Maurya Empire

2. The Akkadian Empire

3. The Assyrian Empire

4. Teotihuacan

5. The Songhai Empire

6. The Srivijaya Empire

7. The Ajuran Empire

8. The Turkic Khaganate
