CHIOS has been founded on one basic premise: Europe and the strained transatlantic community urgently need a renewal of deep, bold and historically informed strategic thinking about international order if they want to cope with and thrive beyond the current “polycrisis”. They are faced with a fundamental challenge: not only to rebuild the eroding Euro-Atlantic peace order but also to create a more sustainable and inclusive world order for the 21st century.
To foster such a process of renewal is the guiding aim of the Centre for History, Strategy and International Order at Helmut-Schmidt-University. Designed as a new strategic hub, CHIOS encourages substantive transnational research, informed public debate, and dialogue between historical experts, strategists and decision-makers. With a special emphasis on Northern Europe, it pursues this mission in close cooperation with the University of Copenhagen, the University of Florence and a global alliance of strategic partners.
