Vlad was fighting the nascent islam death cult. Since they only understood terror, he responded in a very distinct fashion. They cut off heads, He took them alive and then had them bound and impaled through the ass up through their thorax and let them hang until their corpse rotted and slid off.
A feast of crows indeed.
Romania was the boundary that Islam did not conquer. The modern Romanians have not strayed far from these roots.
