As it is described in the sources the Hazarian khanate had lived in prosperity. Ibn Fadlan (922) tells that the Hazar's traded with honey, candles, flour, velvet and fur.Gerdizi (1048) tells that they traded with agiculture and beeswax. Isthari (930-933) mentions that the sources of the Hazar state treasury consisted of tolls that had been taken from entering points to the country and certain land, sea and river points and the 1/10 taxes from the merchants. El-Mes'udi (944) reports that the Hazar's ran vessels on the sea and the rivers. According to the same sources, there had been very fertile land and a lot of fruit gardens in the Hazar country and these "brought comfort to life".
Within the available possibilities the Hazar's also had build cities. The most important city had be the capital Itil. The other big cities, Semender (near the seaside of Dagistan region) with its 4 thousand gardens around Belencer, Tamtarkan at the point where river Kuban falls into the Black Sea and Sarıgsın (in Arabic sources, Al-beyza) at the sides of river Volga. Sarıgsın, which we can call today "Ak-şehir" in Turkish, had be the east part of capital Itil, which sometimes was called "Hazaran". The west region of the capital, where the khane was resident, was called "Han-balig" (khan city).
The Hazar State, which continued the former Gok-Turk organisation with having the kagan (khan) or Yillig (elig) and ruler (beh, peh) on top, being under the domination of the şad's, tarhan's and tudun's, provided the public order and travel security with his powerful army over the wide range of his domination and realized a real "Hazar Peace" ("Pax Khazarica") in East Europe that lasted during the 7th-9th century. With this purpose they even built the famous Sharkel castle in 835, with the help of foremen they brought from Byzantium, in order to prevent any outer attack on time. As this castle, which is named as Bela Vedza (White Castle) in Russian chronicals was made of white stones and bricks it was named in western Turkish as Sharkel (ak-ev = ak-kale / white-house = white-castle).
