The politics and diplomacy of First World War are a complex topic. Tens of thousands of books, articles, and editions of primary sources were published on many aspects of the question, but very few works try to cover the ground comprehensively. The reason is the sheer complexity. The attempt to cover the topic in its entirety and in depth would fail to amalgamate the enormous amount of information. There is not a simple “line of events” to follow. A thorough analysis of the politics and diplomacy of First World War has to cover the events and the political intentions and actions of key protagonists, and then to link them with internal politics, with military events and strategic expectations—and this for the entire duration of the war. The task is massive; over thirty states fought in this war. Many neutrals as well as non-state-actors, like for example the churches, would have to be included in such a survey. It is evident that it is very difficult to deliver such an analysis for the entire period of the war in reasonable depth; and maybe it would not even be sensible to try. Many studies analyze developments in politics, strategy, and war aims on the level of single states or on the level of wartime alliances, or they examine single political events of international nature. What is missing are not the “unit level” studies, but “system level” analysis of First World War diplomacy and political relations covering the entire war. We have to pay a significant price for the non-existence of thorough international studies of the war. It leads to serious and unavoidable shortfalls in interpretation because the “unit level” view—let’s say, the view of the contemporaries living during the Great War—tends to survive and perpetuate itself and to dominate research up to our present times. This bibliography reflects this state of research, by offering first an introduction to some key works on the start of the war (i.e., the July crisis) and introducing then some useful studies which cover the entire topic of international politics and wartime diplomacy. It will then turn toward the politics and diplomacy of First World War on a “unit level,” state by state. It ends with literature on the armistice in 1918. It abstains from covering the Versailles peace negotiations which are a closely linked but separate topic.
