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 city's inhabitants. 

now lets discuss

1., cant see where Ottoman empire was seen as a federation here.
2. none of the byzantine monuments were destroyed in the siege so its impossible to understand what u r talking about.
3. Yes it had a supply system before but also other infrastructure systems were built

so i cant see a reason to delete that part. ( )
