#the visceral tragedy of thessalonike's life always gets me

“Alexander the Great had three sisters - Cynnane, Cleopatra, and Thessalonice - and all three were eventually murdered. Since both' of Alexander's sons met similarly violent ends, it may appear at first glance that little distinguishes the pathetic life and death of each of these three royal sisters from the more pathetic and yet shorter lives of their nephews. Indeed, even earlier in the century, before the long and troubled demise of the Argead house had begun, very few male Argeads managed to die at home in bed.

On reflection, however, the very fact that a long dynasty was coming to an end should have meant that the sisters of the last king would have a better chance of survival than the minor male heirs of that king. After all, once the father is dead, the heirs are for practical purposes (assuming they are well below the age of maturity) no man's sons, and can do no would-be dynast any more than short-term good, whereas the king's sisters can be married and thus legitimize the seizure of royal or quasi-royal power. Better yet, a king's sister may produce children of the blood of the old royal house, as well as the new.

But two of Alexander's sisters did not realize the potential advantage seemingly inherent in their situation and ultimately all three died exactly because they were Philip II's daughters and Alexander's sisters. This failure to realize the potential to be the bridge between two dynasties is most surprising in the case of Alexander's full sister, Cleopatra. Analysis of the careers of Alexander's relatively obscure sisters, worthwhile as an end, in itself, should answer the question of why the Successors proved to prefer murder to marriage (in two of the cases) as well as produce important information about the nature of Macedonian monarchy in a period of great and rapid change. The significance of the similarity in ultimate fate of the three sisters and their nephews has been ignored for too long.  

“...   Calling Alexander's sisters his "relicts" is meant to convey two truths about  them: their similarity to the other relics of Alexander (his corpse, his tent, and,  of course, his empire) and their manipulation by various of the Successors  and (by means of allusion to the older meaning of "relict" as a female survivor  of some related and now departed male, with its implication of the lack of a  separate existence for such women) their peculiarly property-like quality in the  period after the death of Alexander. The answer to the question posed initially - why did Alexander's sisters fare so poorly and so similarly to their nephews - should now be clear. Alexander had no successor. Even Antigonus, although interested in the same land area as Alexander, was not a true successor to the curious monarchy Alexander had invented - a traditional national monarchy onto which a curious sort of personal monarchy had been grafted - Antigonus was, like the other generals, on the way to creating a personal monarchy. Thus even he did not really need Cleopatra. Cassander, with his marriage to Thessalonice and at least superficial attempt to imitate the traditions of Macedonian monarchy, could not really be Philip's heir because he could not be an Argead; he had murdered Argeads and would probably have liked to murder more. Until the death of Alexander, Macedonian kingship had been tied to one dynasty. This was so much the case that the kings used no title, but simply signed themselves as so and so, son of an Argead. Trying to decide whether Philip's or Alexander's reputation was greater after 323 is ultimately devoid of any real political meaning; neither had any real successors and thus Alexander's sisters and Philip's daughters, representing as they necessarily did continuity with what had come before, could have no future.  

Cynnane died in an ill-advised attempt to take royal power by military and quasi-military means; the army did not save her. Thessalonice died in the death throes of the pseudo-dynasty Cassander had fabricated, her death demonstrating that even her son did not need to see himself as the heir to the  Argeads. Cleopatra died making one last attempt to function as a symbol of continuity, and for that she was murdered. The sisters were expendable because continuity was neither needed nor genuinely desired.”

Elizabeth Carney, “The Sisters of Alexander the Great: Royal Relicts”

*I disagree that Cynnane's attempt to take royal power was ill-advised. As Carney herself points out in another book, "although this daring plan ultimately proved fatal for Cynnane, it succeeded in its object and was brilliantly conceived".
