As protection against raging nomads from the Eurasian Steppes, Chinese Emperors deployed labour forces to build qualitative fortifications. Alas, it didn't stop some invading hordes conquering the country: Qin, the first dynasty of the united empire, initiated the project, while Qing, the last dynasty in that empire, crossed it to take power overthere. Manchuria is a region in Chinese Tartary, whereof cartographer John Cary drew the borders:
- The border with China follows the path of the Ming Wall
- The border with Russia is according the Treaty of Nerchinsk
Before Pugachev's Rebellion it seemed to belong to Great Tartary, together with Siberia & Turkestan, but Crimea was known as the distinguished Little Tartary: Were they even earlier united as one Tartary? On its borders with Persia, near the Caspian Sea, we also find walls:
Dhu Al-Qarnayn or Alexander the Great might have built them to isolate Gog of Magog: In the Tartarus, where Giants are buried? In England, Gogmagog was killed by a companion of Brutus of Troy, as Goliath fell ...
Throughout Europe, the supposed descendants of Aeneas of Troy constructed the Roman Limes to keep nomadic tribes outside the empire, ranging from the Black Sea to the Atlantic Ocean, with the following extremities:
- Trajan's Wall to keep the Scythians out
- Hadrian's Wall to keep the Scots out
Did all those fortifications act as fences between a Heartland of a world-empire & the first parts of a separating Rimland?
