In respect to the pinned post, no rush on this question whatsoever! I just, to be honest, wanted to see if I could fact check (or get your opinion) on a "take" that I keep coming across without an associated source? There's a likelihood that you might have seen it too in regards to how, whenever Fatma Sultan, Selim I's daughter is mentioned, there always seems to be someone that brings up a tale that she was at odds with Hürrem in real life and "exiled" from the capital as a result of her "schemes."
Is this just another case of what's in the show bleeding into people's assumptions about the historical reality or is there some basis of truth to it?
Hey! Could I blow your mind with something? After having done archival-level research across primary Ottoman, European, and Safavid sources— it appears that Sultan Selim I only had 3 daughters who survived into adulthood: Şahzâde (Hanım) Sultan and Beyhan Sultan (both born of Ayşe Hafsa in the early 1490s in this order) and Şah Sultan (born before 1505 of an unknown concubine who was alive as of November 1556).
I had made an in-depth thread a couple of months back elaborating about these sources, if you would like to read for yourself, here!
Please take your time with this thread because, I'm afraid it's quite lengthy, haha and I know prima-facie my claim seems bizzare— I had been researching on this topic (Selim I's daughters) intermittently since over a year (especially when I had been sick, it was a welcome distraction in a way, I guess).
So, essentially, how Historian Eda Öner had rather recently illustrated in her article (the extract of which I've appended in the aforementioned link), Kara Ahmed Paşa was in fact, married to a certain “Fatma Sultan, daughter of Mustafa Bey”, so that she must've been a grand-daughter of Sultan Bayezid II via one of his daughters (perhaps, someday when I have more time, I might pin-point which one, but Bayezid's family is very large and then, tracing the sons-in-law with such a common name as Mustafa would be quite something 😭)
Fatma — as a matter of fact— did have a land dispute with her niece, Mihrümah, instead (regarding the location of mosque complex) but Süleyman of course, ruled in favour of his daughter rather than his executed-in-disgrace former Grand Vizier.
That said, given Hürrem's decisive role in the deposition and execution of her husband, Fatma must've hated her guts (it's always a two-pronged vehicle when you contextualise these executions— Hürrem, of course + also, Kara Ahmed had proven himself to have been an incompetent Grand Vizier, even though he was a courageous and militarily-competent man, that's why he was popular with the Janissaries while Rüstem wasn't, interalia; Ahmed'd also conspired in tandem with Cairo Governor Dukakinzade Mehmed Paşa against Semiz Ali Paşa, another one of Hürrem's men— in fact, one whom she'd initially preferred over Rüstem, so yeah...)
(ETA: I do think the execution specifically rather than mere deposition— was kind-of Hürrem avenging the False Mustafa affair that put Bayezid in disfavour with Süleyman— which she had to smooth over, like for instance, Ambassador Ogier de Busbecq had illustrated in his letters + Kara Ahmed's scheming against Semiz Ali...)
I'll also add that due to his mother-in-law's protection, Rüstem had continued to be alternative foci of power even in political exile and Ambassadors continued to treat him as GV (as Rüstem himself claimed that he'd be Grand Vizier again very soon, lol and regardless of his deposition, he commanded the reverence of everyone since he was the Padişah's son-in-law).
We can imagine how all of this must've been such a head-ache for Kara Ahmed and his wife in an already turbulent timeline of ~2 years (October 1553 - September 1555) for which he had been Grand Vizier— sandwiching Rüstem's Grand Vizierates.
Honestly, who says we need to manufacture drama for Ottoman history, there's SO SO much, if we really research scrupulously and thoroughly!
Anyways, I hope that helps! :)
