Alexander founded 70 cities; Genghis Khan, an empire without bricks

Can an empire be the largest in history and not leave behind a single building? The comparison between Alexander the Great and Genghis Khan is back in the spotlight with a stinging statistic: the Macedonian founded more than 70 cities and settlements in less than two decades, while the Mongol, ruler of the largest territory ever controlled by a single man, founded none. The contrast, repeated ad nauseam in any dinner-table conversation, has more edges than it seems.

What each empire actually built

The starting argument is simple: Alexander did not just conquer, he also urbanized. Libraries, temples, art and civilization marked his advance. Genghis Khan, by contrast, is remembered for destruction and plunder. The criticism is not new, but the figure of 70 foundations has become the mantra of those who see the West as the sole source of civilization.

However, history is more nuanced. The Khan's descendants did found cities, starting with Beijing. Genghis himself created meritocratic structures that allowed a multinational empire to function on an unprecedented scale. And his policy of religious and commercial tolerance, with networks that united Asia for the first time, does not fit the portrait of a pure predator.

The demographic legacy: zero versus millions

There is one figure that tips the scales: Alexander's direct descendants number zero. His son, Alexander IV, was murdered and the dynasty died out. The Khan's, by contrast, number in the millions. According to widely circulated estimates, 0.5% of the world's population would be descended from him. The comparison, brutal, leaves the Macedonian without a biological successor.

The contrast is not only numerical. Alexander inherited a political and military machine; Genghis was an orphan fallen on hard times who gnawed on yak carcasses before becoming the most powerful man of his age. Denying merit to that trajectory is denying the evidence.

The Black Death and trade: two faces of the same empire

Among the Mongol contributions, the opening of trade routes between Asia and Europe appears on both sides of the ledger. The security provided by Mongol armies made it possible to consolidate networks that linked the continent. But that same connectivity exported the Black Death to Europe. What a mess they made.

The discussion often drifts into murkier territory. Some argue that the Mongols destroyed the caliphate and with it the Sarracinic golden age. Others point out that Alexander also razed Persepolis and its library. Destruction was not the exclusive preserve of the steppes.

The problem with comparing civilizations by their bricks

The comparison reveals more about the person making it than about the empires. The West creates, the East destroys, the story goes. But the Mongols knew how to rely on local structures, accept foreign customs and allow kingdoms to survive after the Khan's death. They were not that clueless.

In the end, the question is not who built more, but why we keep measuring civilization in stones rather than systems. Alexander left cities. Genghis left a method. Neither asked historians which they preferred.
