Between the years 700 AD to 1500 AD, the Greek peoples have fought Occidental invaders with amazing resilience and innovation. In order to stop the giant armies of Turks, built from a coalition of Sudanese, Afghan, Persian, Kurd, Bedou, Syrian, and Turkic tribal forces, the Greeks brought amazing innovations to war such as the flamethrower.
Over and over and over again, they halted armies several times their size.
While, for some reason, I would have my Occidental biases, and I do root for the Eastern powers to always win every time I read a historical story, I do wonder whether the Greeks may have made the world better for all of us. In each of their battles, they had a 50/50 chance of winning, but they used their wits to change the odds.
Had the Greeks lost sooner, Ottoman armies would have marched across Venice, Florence, Bourdeaux, London, and Valencia. And the world…simply would have not been the same.
I don’t know whether it would have been worse, per se.
But with the typical Ottoman lack of respect for stability and foregoing one’s own interests in the name of protecting any higher authority, fratricide and civil wars would likely have been more common. The Emir of Al-Londoni and the Sultan of Roma would have never negotiated and would burn France down trying to get control over it. Five-way battles between Atapakas of Madrid, Bashir of Bern, Shahrukh of Amsterdam, Barkha of Milan, and Malick of Paris would have been the norm.
