That said, Alexander wasn't very good at what we might now call empire building. Alexander's empire is definitely visually impressive, but it wasn't actually much of an empire. Like, Alexander specialized in the tearing down of things, but he wasn't so great at the building up of institutions to replace the things he'd torn down. And that's why pretty soon after his death, his empire broke into three empires, called the Hellenistic Kingdoms. Each was ruled by one of Alexander's generals, and they became important dynasties – the Antigonids in Greece and Macedonia, the Ptolemies in Egypt, the Seleucids in Persia – all of which lasted longer than Alexander's empire itself. A second kind of greatness – maybe Alexander was great because he had an enormous impact on the world after his death. Like King Tut, Alexander the Great was amazingly good at being a dead person.
