On 12 November 1918, in the wake of civil unrest in the last days of the war, Rupprecht's father, Ludwig III, promulgated the
Anif declaration releasing his officials, officers and soldiers from their oaths. Although he did not formally abdicate (and some loyalists would continue to refer to Ludwig as king), the declaration was interpreted by the government of Bavaria as an abdication, making Bavaria a republic and ending 738 years of Wittelsbach rule; Rupprecht thus lost his chance to rule Bavaria. Rupprecht escaped to
Tyrol in fear of reprisals from the brief
communist regime in Bavaria under
Kurt Eisner but returned in September 1919. While away from Bavaria, he succeeded his mother,
Maria Theresa of Austria-Este, the last Queen of Bavaria, as the
Jacobite heir. This occurred upon her death on 3 February 1919. As such, under his anglicized name, he would be King Robert I of England and King Robert IV of Scotland, although he never claimed these crowns and "strongly discouraged" anyone from claiming them on his behalf. The changed political situation however allowed him finally to marry
Princess Antonia of Luxembourg on 7 April 1921. The
nuncio to Bavaria, Eugenio Pacelli, later
Pope Pius XII, officiated at the ceremony. Shortly after the 1922
Washington Naval Conference, he made a statement regarding the possible ban of
aerial bombing,
poison gas, sea blockades and long range guns, blaming them for a majority of civilian casualties during the last war. He also advocated Germany's participation in future peace conferences, and he dismissed claims that Kaiser
Wilhelm II was to blame for the First World War. While opposed to the
Weimar Republic and
never having renounced his rights to the throne, Rupprecht envisaged a
constitutional monarchy for Bavaria. Upon his father's death in October 1921, Rupprecht declared his claim to the throne, since his father had never formally renounced his crown in the
Anif declaration. While never crowned king, he did become the head of the
House of Wittelsbach after his father's death. He formed the
Wittelsbacher Ausgleichfond in 1923, which was an agreement with the state of Bavaria, leaving the most important of the Wittelsbach palaces, like
Neuschwanstein and
Linderhof, to the Bavarian people. Afterwards, Rupprecht became critical of wars like
World War I. Rupprecht once said to
The New York Times that the
Washington Naval Conference would be able to make future warfare more humane. Rupprecht added that future conferences would entirely abolish chemical warfare. The anti-Catholic stance of men like
Erich Ludendorff might have been an influence. Hitler confided in private to a personal dislike of the Crown Prince. The Crown Prince in turn confessed to King
George V at a lunch in London in the summer of 1934 that he considered Hitler to be insane. With the worsening of the
Great Depression in 1932, a plan was floated to give Rupprecht dictatorial powers in Bavaria under the title of
Staatskommissar. The plan attracted support from a wide coalition of parties, including the
SPD and the post-war Bavarian
Minister-President (First Minister)
Wilhelm Hoegner but the legal appointment of Hitler as
Reichskanzler in 1933 by
Hindenburg and the hesitant Bavarian government under
Heinrich Held ended all hopes for the idea. Rupprecht continued to believe that restoration of the monarchy was possible, an opinion he voiced to the British ambassador
Eric Phipps in 1935. ==Second World War==
