The course examines different diasporas, i.e., the Jewish diaspora, the Armenian diaspora, the African diaspora, the Chinese diaspora, the Indian diaspora, the colonial diasporas, the Greek diaspora, etc. Through a comparative approach, it analyzes in detail the transformations of national identity, the links with the mother country, and the relationship with the hosting country. Despite important differences in the way they have been constructed (violence, forced movement, voluntary exodus, etc.), diasporas share several common characteristics. The course aims to familiarize students with issues of migration and the construction of diasporas and focuses on the cultural aspects of the phenomenon.
