In studying the Ottoman Empire i've noticed that a number of Sultans have been assassinated from within their court. I haven't tried to count it or anything, but it at least seems like a fairly common occurrence, especially in the Empire's long decline.
Compare this to royalty in Europe where, where plenty of Kings have died from illness, war and even jousting accidents, the incidence of assassination (On the surface) seems low, especially from within their own house court.
I am wondering firstly if this is true, and if so why assassination was more frequently seen among the Ottomans. Did they simply have a more practical view of their leaders than the 'Divine Right' espoused by Christian monarchy, or was it something else?
I can't really say anything about the comparison between Europe and the Ottomans. However, the reason you are seeing A LOT of dead princes is probably due to Mehmed II allowing the murder of brothers to secure the throne. That system also resulted in fathers charging their sons with treason and killing them, and vice versa.
The benefit of this however, is that we see far less civil wars in Ottoman Empire than in major European powers. That, I am fairly sure of.
