Leibniz Institute of European History Mainz, Alte Universitaetsstraße 19, 55116 Mainz, Germany Writing European history calls for the crossing of boundaries and borders. As a dynamic space of communication and transfer, »Europe« transcends states, empires and nations both within the continent itself and in a global world. In recent years historical research has taken up this challenge and has increasingly paid more attention to such transcultural and transnational dynamics bringing forward a reflexive understanding of historical processes. However, this research has also demonstrated the significance of constructing and imagining boundaries in European history.
