I want to know the answer to the following question:
How were these relationships with the other countries most likely established ?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: yes
