Germany's Aims in the First World War (German title: Griff nach der Weltmacht: Die Kriegzielpolitik des kaiserlichen Deutschland 1914–1918) was a book by German Historian Fritz Fischer. It is one of the leading contributions to historical analysis of the Causes of World War I, and along with this work War of Illusions (Krieg der Illusionen) gave rise to the "Fischer Thesis" on the causes of the war. The title translates as "Grab for World Power". or "Bid for World Power". Essentially Fischer attempts to link together a continuum of German belligerence in their "grab for power" weaving it all together into a cohesive theme of German Weltpolitik.
