The rise of pan-Arabism, which occurred in the Arab world mainly between 1948 and 1967, was characterized by both the hegemony of a nationalist ideology and the effort to rearticulate and unite those spaces once controlled and divided by European colonialism. The concept of an indissoluble Arab nation and the necessary awakening of unity consciousness and its political and economic concretion, became the fundamental objective of an entire generation. These ideas impacted and were resignified by the Arab communities settled in Chile, since they maintained ties with their societies of origin, manifesting themselves in the discourses, actions, the emergence of institutions of the community and the tendency to unify them over the regionalisms, following the principles and values that Arab nationalism spread. This article addresses the impact and meanings constructed by Arab immigrants and their descendants in Chile around Arab nationalism, first outlining their gradual emergence in the period of colonial consolidation between 1918 and 1948 and then analyzing their hegemonic stage.
