Chian network
The network was comprised by the Greek merchants who were active commercialy in the Black Sea, in the Mediterranean and in Western Europe during the period 1830-1860. The most important merchants originated from the island of Chios and very often were connected with kinship ties. These merchants combined trade with shipping and their companies were characterised by discipline and cohesion. The most important families were those of Rodokanakis, Zizinias, Rallis, Dromokaitis, Petrokokkinos, Agelastos. The network's importance declined with the changes in Black Sea trade after the Crimean War (1853-1856), in connection with the technological changes in sea transport.
