Calling the Ottoman empire a relatively quiet backwater is wild. There was a ton of conflict and it was a huge trade and culture hub. It had its highs and lows. Even its the most peaceful times (which followed decades of war) it was a wack a mole of rebellions.
A relatively quiet backwater damn dont let a Turk hear you disrespect the Ottoman empire like that.
Why do you act like it was aliens coming from space? It was just humans doing what they've always done. Do you think they didnt know what war was? They had been warring for millennia with other people from Europe, Asia and Africa.
