<span>The current thinking is around 200,000 years ago, but I would argue against this by saying that humans had not yet developed the same mental capacity that we have today, as some cognitive ability would have been needed in making art, which of course seems to have appeared around 70,000 years ago in its geometric form, where as the figurative animal paintings and carvings came to be around 40-35 thousand years ago. So, humans were physically definitely modern around 200ka, but mentally, this is unlikely. It is of course possible to argue that behavioural changes need not to be dictated by physiological or cognitive changes. Art could just be an invention</span>

Ottoman Empire represents on of the largest imperial projects in the history of humans, ruling vast territories in North Africa, the Balkans, and the middle east over a period of some five centuries. It was created by Turkish tribes in Anatolia that became one of the most powerful states in the world during 15th and 16th centuries.  The central fact that allowed Suleiman to peruse urban renewal projects was the fact that his revenues from the state were higher than those of other European monarchs.
