  1. ^ a b c On 17 July 1918, the 1918 Franco-Monégasque Treaty was signed, caused by the unwillingness of France to accept the potential succession of Wilhelm Karl, Duke of Urach, a German prince, in the context of World War I[1][2]. This limitation originated the Monaco succession crisis of 1918. While the 1918 treaty was in force (from 1918 to 2002), the succession to the throne was limited to the descendants of the current Sovereign Prince[1].
  2. ^ On 16 May 1919, Charlotte Grimaldi de Monaco, Mademoiselle de Valentinois[3], an illegitimate daughter of Hereditary Prince Louis (at the time unmarried and without legitimate issue), was formally adopted by him, with the approval of the Sovereign Prince, Albert I, solving the Monaco succession crisis of 1918[1][4].
  3. ^ a b On 30 May 1944, Hereditary Princess Charlotte renounced his claim to the throne in favor of her son, Prince Rainier, on the eve of his 21st birthday, subject to the stipulation that he not predecease her without issue[1][6].
