I just reviewed a fascinating analysis about the largest empires in history, and there are details that really put into perspective how territorial power has been redistributed over the centuries.

The first thing that catches the eye is that the British Empire dominated with 35.5 million km², which is absolutely colossal considering it was mainly built through trade and naval power. But if we talk about pure territorial conquest, the Mongol Empire with 24 million km² achieved something that many underestimate: it was the fastest to expand.

Then we see how Asian powers like the Qing Dynasty reached 14.7 million km² and the Yuan Dynasty reached 11 million. Even the Abbasid and Umayyad Caliphates hovered around 11 million each. The interesting part is that these largest empires in history often overlapped in time, but never in territory.

In the West, the Spanish Empire with 13.7 million km² and the French Colonial Empire with 11.5 million were serious players, although their expansion was later. The Portuguese Empire, often forgotten, reached 10.4 million km².

What surprises me is how after World War II, the United States accumulated 9.8 million km² in territories, showing a shift in expansion strategy: it’s no longer about direct conquest but about geopolitical influence.

If you look at the full ranking, from the Roman Empire with 5 million to Ancient Egypt with only 1 million at its peak, you can clearly see that the concept of empire has evolved. The ancient ones were more concentrated, the modern ones more dispersed. Definitely, understanding these data helps us comprehend why the current world is divided the way it is.
