Book excerpt: This ancient military history examines how the Macedonian empire descended into a maelstrom of violent rivalry after the death of Alexander. When Alexander the Great died in Babylon in 323 BC, he left behind one of the largest empires the world had seen, stretching from Greece to the Punjab. Surrounding the king’s deathbed were his highest subordinates: some of the greatest military minds of antiquity, each with their own insatiable ambitions for power. Since Alexander died leaving no clear successor, these former brothers-in-arms quickly became fierce foes as they vied for dominance. What followed was an extraordinary time for military campaigns. Powerful warlords and warrior queens attempted to assert their authority throughout the length and breadth of Alexander the Great’s former empire; from Afghanistan to Athens, from Africa to Asia, powerful armies decided matters by the spear. In this volume, historian Tristan Hughes looks at the initial years of the conflict and several major campaigns that immediately seized the kingdom.
