I found it interesting that despite having so many women in his life (in wife/lover figures), Hasan has yet to have a son. In the culture back then, it was very important to have a son to carry on the family name and be the heir to the family fortune. I wonder if this small detail will unfold into something bigger later in the book, or if it just an insignificant detail. I also found the fate of Hasan in regards to Bayazid to be very ironic. However, how Hasan responds to the situation shows great character, morals, and courage. Hasan seems to be a very honest, smart and compassionate man.
This is more of a history question - but diplomatically, what exactly was happening between the Ottomans and the Mamelukes? It seems as though in the Muslim world, the Ottomans were the "big boys on the block." That probably meant that after their fall after WWI there were a lot of problems in the Muslim world - as they were.
