after the Landtag passed a law allowing him to do so, Ludwig ended the regency, deposed Otto and declared himself King of Bavaria as Ludwig III. The Prinzregentenzeit ("prince's regent's time"), as the regency of Luitpold is often called, was due to the political passiveness of Luitpold an era of the gradual transfer of Bavarian interests behind those of the German empire. In connection with the unhappy end of the preceding rule of King Ludwig II this break in the Bavarian monarchy looked even stronger. Finally, the constitutional amendment of 1913 brought the determining break in the continuity of the king's rule in the opinion of historians, particularly as this change had been granted by the Landtag as a House of Representatives and meant therefore indirectly the first step from constitutional to the parliamentary monarchy. Today the connection of these two developments is regarded as a main cause for the unspectacular end of the Bavarian kingdom without opposition in the course of the November revolution of 1918. However the course of his 26-year regency Luitpold knew to overcome, by modesty, ability and popularity, the initial uneasiness of his subjects. These prince regent's years were transfigured, finally—above all in the retrospect – to a golden age of Bavaria, even if one mourned the "fairy tale king" Ludwig II furthermore what happens in a folkloric-nostalgic manner till this day. Military autonomy With the establishment of the German Empire, a series of conventions brought the bulk of the various state military forces directly under the administration of the Prussian War Ministry. Bavaria however maintained a degree of autonomy in peacetime, with its own two (later three) army corps remaining outside the Prussian order of battle. The Bavarian infantry and cavalry regiments retained their historic light blue and green uniforms, distinctive from the Prussian model adopted throughout most of the army. The individual Bavarian soldier swore an oath of loyalty to King Ludwig, though in wartime this pledge of obedience was extended to Kaiser Wilhelm as supreme commander. In July 1914, the Bavarian Army numbered 92,400 or 11 percent of the total Imperial Army. World War I and the end of the kingdom In 1914, a clash of alliances occurred over Austria-Hungary's invasion of Serbia following the assassination of Austrian Archduke Franz Ferdinand by a Bosnian Serb militant. Germany went to the side of its former rival-turned-ally, Austria-Hungary, and declared war on France and
