World War I 1914–1918
The German Army that fought in World War I was not in fact a single, unitary army. All the monarchies (Great Dukedom of Hesse, Great Dukedom of Baden - as example) as a part of the German Empire had its own armies.

Since the unification of Germany in January 1871 most of them were under Prussian command, though each continued to wear its own style of uniforms and insignias. The four German kingdoms that existed since the Napoleonic era - Bavaria, Prussia, Saxony and Württemberg - of course had its own armies until the end of WWI. The commander in chief in peacetime of each of these armies was the King. Prussia had the largest army of the four.

After the unification and the formation of the German Empire, the Prussian army became the nucleus of the Armies of the German Empire. After the declaration of war, the emperor became the commander-in-chief of all the armed forces. By 1914 the German army fielded 50 active divisions and 48 Reserve-Divisions - by 1918 251 divisions had been create.
