This article examines how Syrian immigrants in Argentina responded to the intersection of transnational politics and nascent nationalisms between 1900 and 1922. In particular, it studies the role of Syrian intellectuals in Argentina in advocating a variety of political allegiances that changed over time as their homelands suffered a series of intense political transformations during the first two decades of the twentieth century. The emergence of Syrian and Lebanese ethnic identities as well as an Arab racialised identity was the product of distinct political programmes circulating in the Levant and among the Syrian émigré communities in the Americas, threatening to undermine the immigrant colony's sense of community.
