The debate surrounding German Social Democracy during the era of the Second International represents an important chapter in the historiography of post-Second World War Italy. At the same time, it also marks some crucial moments in the political and intellectual life of Republican Italy. This article aims to show the close relationship between the investigation of the past and the ongoing political struggle that has characterised research on this issue. Study of the topic was practically monopolised by left-wing historians, who, in dealing with the history of German Social Democracy, aimed also to direct the political strategy of workers’ parties. Considering the studies appearing after the 1956 crisis and in the mid-1970s, such a goal seems evident. It was only during the 1980s that the research opened itself to different perspectives – no longer influenced by ideological controversies.

The Italian political crisis of 1993–1994 and the new political dynamics to which it gave rise, and which persist today, have strongly shaped both public debate and historiographical reflection on the Italian Republic. This article assesses the impact of the political changes of the post-1994 period (and notably Berlusconi's entry into politics) on the debate over the so-called First Republic, with regard to: Italian national identity in the post-Fascist period; the functioning of the political system, especially in relation to the role of the political parties; anti-Fascism and its internal divisions; communism and anti-communism.
