Current scholarship on empire considers those Britons engaged in processes of colonisation as culturally homogeneous, but this view negates their cultural complexity. From the first forays of the Port Phillip Association, Jewish settlers and investors have been attached to Melbourne. Although those settling in Melbourne were themselves predominantly British, they brought with them not only the networks of empire, but also the intersecting diasporas of European Jewry and the new and expanding English-speaking Jewish world. This thesis considers how the cosmopolitan outlook and wide networks of the Jewish community helped shape Melbourne.
