German Empire
The high command under Paul von Hindenburg and Erich Ludendorff increasingly controlled the country, but in October after the failed offensive in spring 1918, the German armies were in retreat, allies Austria-Hungary and the Ottoman Empire had collapsed, and Bulgaria had surrendered. The Empire collapsed in the November 1918 Revolution with the abdications of its monarchs. This left a postwar federal republic and a devastated and unsatisfied populace, which later led to the rise of Adolf Hitler and Nazism.
Margraviate of Brandenburg
The Margraviate of Brandenburg ended with the dissolution of the Holy Roman Empire in 1806. It was replaced after the Napoleonic Wars with the Prussian Province of Brandenburg in 1815. The Hohenzollern Kingdom of Prussia achieved the unification of Germany and the creation of the German Empire in 1871. As Prussia was the legal predecessor of the united German Reich of 1871–1945, and as such a direct ancestor of the present-day Federal Republic of Germany, Brandenburg is one of the earliest linear ancestors of present-day Germany.
