Tourism is not apolitical. The development of this field has diverse, complex, and contradictory economic, political, social, cultural, and environmental impacts. The revenues derived from international tourism continue to break records: 1.035 billion people traveled for leisure in 2012. Thus, tourism has become a mass practice. The history of international tourism in the last 50 years can be divided into three stages: (1) the period of 1950-1980, which were characterized by a gradual democratization of tourism supported by sustained economic growth; (2) the 1990s, which were marked by an euphoric tourist market that pushed for increasing access across the globe for international tourism; and (3) the years following 2001, which are marked by maturity in the field of tourism. The ecstatic vision of a world without borders was met with harsh reality after the tragic events of September 11, 2001, leading to increased awareness of the complexities for tourism in a world fraught with conflict. Selective diffusion of global tourist flows is the current economic and political logic driving the tourism industry and translates into sophisticated business relations. The climates of insecurity that affect some fragile tourist destinations in the periphery are more sensitive to the expansions and contractions of international tourist markets.
