Afghani'd claim that Alexander the Great did not defeat Afghanistan or the Patans (Pukhtoon) people. Is this true or is it only a myth?
In Alexander the Great's time the region of Afghanistan was known as Bactria. Alexander overran this region but had trouble managing it. Nominal ownership remained that of the successors of Alexander's empire, eventually phasing into the Macedonian-based Seleucid Empire. During my time in Afghanistan, old architecture could still be seen dating back to Alexander's conquest.
There is a claim by Afghans that they were not defeated by Alexander because they maintained an insurgency during the foreign ownership. As with so many other foreign invaders to the region (including Genghis Khan and the USSR), the Afghans claim to have always resisted and outlasted the outsiders. In other words, "We were here before they came and we were still here after they left."
