Alexander's wealth came from rapid, aggressive territorial conquest—he'd move armies across continents at unprecedented speed, extract tribute from conquered kingdoms, and move on. It was a blitzkrieg wealth model: fast expansion, immediate extraction, minimal consolidation. By 32, he'd hit a ceiling because he literally ran out of map; his empire fractured immediately after his death because it was built on military momentum, not institutional infrastructure. His $750M was real but ephemeral—a personal war chest rather than generational wealth.

Napoleon took a different approach: he conquered slower but built deeper. While Alexander was racing through Persia, Napoleon spent 15+ years systematizing French territory, establishing the Napoleonic Code, and consolidating property holdings. He acquired the Tuileries Palace, vast French estates, and personal landholdings that threw off continuous revenue. His wealth generation was less about one-off plunder and more about owning appreciating assets and controlling tax-generating infrastructure. Even in exile, Napoleon maintained significant property wealth that couldn't be stripped away like tribute could.

The real kicker: Alexander's $750M was mostly illiquid—it was tied up in tribute obligations and territorial control that vanished when he died. Napoleon's $1.2B was more diversified across real estate, title deeds, and established properties that retained value post-empire. In modern terms, Alexander was all stock (volatility spike), while Napoleon had built a balanced portfolio (bonds + property). That's why the Corsican's number is 60% higher—better asset diversification and institutional longevity.
