An analogical story or how do mega-events make it possible to rethink tourism as an instrument for the globalization of societies? From Barcelona to Paris via Milan[¿Una historia analógica o cómo los megaeventos permiten repensar el turismo como instrumento de globalización de las sociedades? De Barcelona a París vía Milán]

Subject: This is a proposal that is both theoretical but taking as a stand to propose an alliance between a synchronic and diachronic history through an exceptional research object, theworld expo / world's fairs. We offer an analysis grid of the global history of our world through the universal exhibitions, but within a renewed framework of our iterative analyzes. Terrain: We take the regional capital of Catalonia, Barcelona and its tourism as our main terrain, through world fairs such as those of 1888, 1929, 1936 (popular Olympics), 1954 Mediterranean Games and the modern Olympic Games of 1992 as mega-events. But beyond this to present our analog methodology, we will focus on European exhibitions in Seville, Milan and Paris as an example, but also American and Asian exhibitions with Osaka and New York. Methodology: An analogical history is proposed and allows us without going into anachronisms to offer a long historical and geographical chain of world expo / world's fair as an element or vector of a global history of tourism. During the conference, we will present the frameworks of this methodology, which is appropriate both for an activity such as tourism but also within the framework of the rewriting of the world history of tourism and the knowledge economy through pre-established grid items. analysis of the event in a time ring. Between a geohistory and a geoeconomy of tourism, we arrive at three main results: a - the universal exhibitions respond to each other over time, long, medium and short; the dynamics of the movement of man-tourists and imaginaries open up to a global history of tourism of which Spain is the champion at the end of the 20th century. b - the means of mass communications offer alternative realities very often on behalf of political and economic actors it is a nebenwelt or side world, another world or a parallel world which is staged and told by building at the both the history of a country, of the host city and the global history of tourism.
