Gazaria (Genoese colonies)

Gazaria (also Cassaria, Cacsarea, Gasaria) was a colonial possession of the Republic of Genoa - a series of semi-exclaves in Crimea and around the Black Sea coasts - from the mid-13th century to the late 15th century.
The name "Gazaria" derives from Khazaria, though the Khazars had ceased to rule over the area well before the Genoese arrived.
Castles.
The colony was officially established with transfer of Caffa by Möngke Khan to the Republic of Genoa, becoming the regional center of the Black Sea colonies. In 1357, Genoeses acquired the colony of Cembalo (today – Balaklava), in 1365 Genoese completely overtook the city of Soldaia (Sudak) from Venetian control.
West Black Sea.
Aside of Crimea, Genoa possessed several castles on the western coast of Black Sea such as the castle of Maurocastro (Bilhorod-Dnistrovsky) in the estuary of Dniester, the castle of Ginestra near Odessa, the castle of Licostomo (Kiliya), the colony of Costanza (Constanța) and the colony of Caladda (Galați).
