Synchronous historiography focuses on studying a specific period of time, examining events, people, and cultures within that timeframe. It aims to provide a snapshot of a particular moment in history. On the other hand, diachronic historiography looks at the development and changes over time, tracing the evolution of events, ideas, and societies across different periods. It seeks to understand how and why things have changed over time. Both approaches are important in historical research as they offer different perspectives and insights into the past. **

The question of war guilt in the First World War is a highly debated and controversial topic in German historiography. In the immediate aftermath of the war, the Treaty of Versailles placed the sole responsibility for the war on Germany, leading to a sense of injustice and resentment among the German population. This narrative was perpetuated by German historians in the interwar period, who sought to shift the blame away from Germany and onto the other major powers involved in the conflict. However, in more recent years, there has been a shift towards a more critical examination of Germany's role in the outbreak of the war, with many historians acknowledging the shared responsibility of all the major powers involved. Overall, the question of war guilt in the First World War remains a contentious issue in German historiography, reflecting the complex and multifaceted nature of the conflict. **
