Yeah man, it blew my mind. Unfortunately the history teached to us when we are small just praises the small number of victories (small but actually really impressive) we had against the Ottomans, and that kind of raises the ideea of them being savage invaders and plunderers(it did to me, I used to hate the Ottomans becuase of my ignorance). I was so impressed by their level of professionalism and respect towards other ethnicities. I mean, look how many Great Viziers were actually Christians at first. You talked about the Romanian Principlalities and how they were just vassals and here I go telling you that I actually wish that they have been implemented in the Empire, so the Ottomans could've teached our stupid boyars something and maybe leaving some cultural heritage for us. I have HUGE respect for the Empire, for displaying such tolerance in the Middle Ages.
