This chapter on the German Confederation examines the largest cornerstone of the new European security system, designed to stabilise the European centre and provide an institutional structure for the cooperation of the thirty-eight remaining German states in relation to the other powers. After addressing and commenting upon the (lack of) historiography on the Bund, the chapter squarely puts this analysis of the Confederation in the context of European collective security operations, with the Bund as one of the pillars of this new post-Napoleonic security edifice, especially tasked with securing a ‘double balance of power’. The chapter ultimately fleshes out the role of the Confederation as laid down in the Bundeskriegsverfassung: to provide security for the states of the German Confederation and at the same time be the ‘pacific state of Europe’ (Heeren).
