The Tibetan Empire
The Tibetan Empire ruled over an average of 3% of the Earth’s surface and existed back in 800 AD. This empire lasted more than 200 years through its successive rulers’ vast knowledge and critical thinking skills. Not many empires last that long.
Checking the map, you can see the numerous landscapes the empire covered. It somehow took control of a lot of the inhabited spaces across the globe.
