this is the part you keep deleting  Mehmed II used the conquering army to restore the physical structure of the city Old buildings were repaired streets aqueducts and bridges were constructed sanitary facilities were modernized and a vast supply system was established to provide for the citys inhabitants   now lets discuss   cant see where Ottoman empire was seen as a federation here  none of the byzantine monuments were destroyed in the siege so its impossible to understand what u r talking about  Yes it had a supply system before but also other infrastructure systems were built  so i cant see a reason to delete that part
