Why does Cihangir hates Selim so much (or me trying to make the writing for Cihangir way deeper than what it actually is part 2)
So Cihangir hates Selim, which can seem very arbitratry because Selim never did anything to him. On top of that since both of them, with Selim to a lesser degree, are considered "inadequate" princes, you'd think they could have bonded.
Building on my last post about Cihangir loving Mustafa as a projection of his idealized self, I'm gonna attempt to give a (pseudo) psychological reason as to why Cihangir hated Selim so much.
Cihangir, unlike his brothers, has essentially never left the palace and has lived a very secluded existence, spent mostly reading books. One can wonder if this hasn't warped his worldview, which is founded on idealism instead of reality. He completely ignores the fact that being a ruler requires ruthlessness, cruelty, pragmatism and the faculty of compromising your morals. He believes rulers should be unwaveringly righteous and just, an ideal he projects on Mustafa.
Selim is the opposite of this ideal, he is a drunk, he's not good at fighting, he lacks discipline, he's cunning and pragmatic, and willing to do anything to survive. He is largely marginalized among his siblings and rather unpopular among the army and subjects. He represents an image of "failure of a prince" to Cihangir, an image he already wrestled with himself and desperately wants to escape.
And yet this "failure of a prince" succeeds where Mustafa fails, first getting Manisa, then being named regent. This creates an unbearable cognitive dissonance for Cihangir : the perfect prince he desperately wants to be is punished, while the "mediocre" prince is rewarded. Selim’s victories aren’t just frustrating—they are an inversion of the natural order in Cihangir’s mind. Selim is proof that the world doesn’t operate on ideals ! power doesn’t go to the most noble, but to the most adaptable. Selim, by thriving despite his flaws, undermines Cihangir’s entire worldview, and Cihangir hates him for it.
That also explains that while Cihangir doesn't worship Bayezid, he still loves him deeply. Bayezid, despite his flaws, still aligns with Cihangir’s moral view of the world. He’s strong, brave, earnest, admires Mustafa. His recklessness is a flaw, but it’s an "honest" flaw.
Cihangir resents Selim because he represents the harsh reality of the Ottoman politics : political success is not about "virtue", it's about cunningness and pragmatism.
