Passage: During and after the Greek War of Independence, Greeks of the diaspora were important in establishing the fledgling state, raising funds and awareness abroad. Greek merchant families already had contacts in other countries and during the disturbances many set up home around the Mediterranean (notably Marseilles in France, Livorno in Italy, Alexandria in Egypt), Russia (Odessa and Saint Petersburg), and Britain (London and Liverpool) from where they traded, typically in textiles and grain. Businesses frequently comprised the extended family, and with them they brought schools teaching Greek and the Greek Orthodox Church.
