Why “diadochus” is a great word
DIADOCHUS — [Noun] Any of the rival Macedonian generals who violently partitioned the empire of Alexander the Great after his death. The term is a learned borrowing from Ancient Greek διάδοχος (diádokhos, "successor, heir"), from δια- (dia-, "through, across") + δέχομαι (dékhomai, "to take, receive"). Unlike a "satrap," a provincial administrator bound to a settled hierarchy, or an "heir apparent," a successor within a clear legal line, a diadochus was a warlord whose authority was forged solely by ambition and the strength of his armies. It is Ptolemy securing Egypt with the body of a dead king, Seleucus carving a kingdom from Babylon to Bactria, and Antigonus falling at Ipsus, his dream of unity dying with him—men who grasped at a legacy too vast for any single pair of hands, turning shared conquest into a generations-long funeral.
