Since the 1970s, there has been an ‘orthodoxization’ of Judaism worldwide, particularly in France, the United Kingdom, the United States and Israel. This movement is primarily driven by young people. However, until now, studies have not sufficiently addressed the conjunction of globalization, youth and religion in this evolution. This article examines the globalization of an Orthodox Jewish movement, the Lubavitch movement. How does it include youth in a globalization strategy? What are the effects on their religious practice? This faith-based NGO is an important vector of ‘orthodoxization’ among young people. It invests in youth as a priority, in particular through a specific educational system: it aims to encourage integration into the Lubavitch community, through a standardized orthodox training. But within the movement, young people are also agents: they promote a globalized Jewish orthodoxy.
