No, it's not a historical map. There shouldn't even be a debate on this.

-Ottoman Empire ala 1800, except with full possesion of Arabia, and no possessions in the Balkans (save Greece)
I would suggest that it's far earlier than that. I'm going with the Umayyad Caliphate with a successful Siege of Constantinople (717). That ugly thing in the West is probably some sort of Battle of Tours (732) Arab success wankfest. I would suggest that Poland is not Polish, or Slavic in origin at all. I would point to it being an Avar Empire. I'm confidentially dating this because of the presence of ah-historical Srivijaya that a certain Wikipedia mapmaker of dubious skill likes to depict in that
exact shape. Also Southeast Asia is a dead give-away. Champa are still going, so are the Khmers, Pegu, Ayuttuya and I presume that grey thing are the Burmese?

There's no Byzantine empire at all so it's post 1543.
With no Russia, Sweden, Norway, England and freaking Lotharingia, Srivijaya, Goguryeo and Silla still tooling around.
Please. If it was an OTL map I would date it to before 936 when Goguryeo united Korea. That would go some way to explaining the omissions and the strange residuals. I can't be a 100% sure, but it can't be that much later, otherwise we would expect to see some sort of Wessex imposed unity in England. Again, not fixed in stone but it can't be that much before or that much after.
