"En la cima más alta de Manhattan". Borders, the Market, and Onís's Hispanism In one of the several articles he devoted to discuss his concept of Hispanism, Federico de Onís represented Columbia as strategic location from which to rebuilt what he called "a Spain without Spain". Located between Riverside Drive and Broadway, the university would be the place to push forward the liberal political and cultural agenda brought to an end by the outbreak of the Civil War; furthermore, it would allow to develop new transnational economic alliances between Spain, Latin America and the United States. In this article, I will focus on this and other locations that Onís conceptualized as "border" sites, paying particular attention to the consequences that such a concept had for the constitution of Hispanism as a discipline. Key concept in Onís, the border is in his work the privileged location where Spain constituted itself as a transhistorical entity, particularly in times of imperial expansionism through warfare and commerce. A kind of parallel version of the Manifest Destiny doctrine, Onís's formulation is inextricably linked to the emergence of Pan Americanism, and like it, unthinkable outside the new place of Latin America in the post-1898 global networks.
