Diadochi conflicts

The Diadochi conflict, also known as Wars of the Diadochi and Wars of Alexander's Successors were a series of conflicts fought during 41 years between Alexander the Great's generals, family members, and friends, after Alexander's death on 323 BCE over the rule of the Macedonian Empire. The conflict started with the Partition of Babylon on 322 BCE.

When the UNSC found the survivors of the several years after its crash, they decided to name the planet of its crashsite "Partition", as a nod to the Partition of Babylon.
