On June 16, “Kossovo Day” was celebrated in New York City. According to the Julian calendar the event was close to the date of Serbian Vidovdan. This chapter focuses on how “Kossovo Day” 1918 was shared with the American public by the Serbian immigrant community. It discusses how the individual and situational migrant context was linked to US media discourses and structures of Serbian migrant organizations; how the Kosovo discourse provided orientation for actions by individuals, but also for political decisions; how migrants kept each other informed via public discourse, but also informed other US citizens about their status as exiles as long as Kosovo was not free. The central figure in this chapter is Michailo Pupin, a Serbian immigrant, who led migrant organizations, pulled the strings during the Kosovo Day event in New York, and worked to gain political support from the United States for the Serbian cause in Europe. The Kosovo myth thus received a supplementary narrative that intertwined the history of the United States with that of Serbia. According to the theoretical approach of the histoire croisée, this chapter investigates the cultural interactions that unfold in a process-like manner over time and which can result in the creation of an international, imagined space or public sphere. The intersections in the process, transfers, translations, and reinterpretations of historical narratives represent the units of analysis. These narratives were brought by Serbian immigrants in the first decade of the twentieth century and implemented in American public discourse.
