Wilhelm, German Crown Prince, Crown Prince of Prussia (Friedrich Wilhelm Victor August Ernst; 6 May 1882 – 20 July 1951) was the eldest child of the last Kaiser, Wilhelm II, German Emperor, and his consort Augusta Victoria of Schleswig-Holstein, and thus a great-grandson of Queen Victoria, and distant cousin to many British Royals, such as Queen Elizabeth II. As Emperor Wilhelm's heir, he was the last Crown Prince of the German Empire and the Kingdom of Prussia, until the abolition of the monarchy.
Wilhelm became crown prince at the age of six in 1888, when his grandfather Frederick III died and his father became emperor. He was crown prince for 30 years until the fall of the empire on 9 November 1918. During World War I, he commanded the 5th Army from 1914 to 1916 and was commander of the Army Group German Crown Prince for the remainder of the war. After his return to Germany in 1923, he fought the Weimar Republic and campaigned for the reintroduction of the monarchy in Germany. After his plans to become president had been blocked by his father, Wilhelm supported Adolf Hitler's rise to power, but when Wilhelm realised that Hitler had no intention of restoring the monarchy, their relationship cooled. Wilhelm became head of the House of Hohenzollern on 4 June 1941 following the death of his father and held the position until his own death on 20 July 1951.

Charles I or Karl I (German: Karl Franz Josef Ludwig Hubert Georg Otto Maria, Hungarian: Károly Ferenc József Lajos Hubert György Ottó Mária; 17 August 1887 – 1 April 1922) was Emperor of Austria, King of Hungary (as Charles IV, Hungarian: IV. Károly), King of Croatia, King of Bohemia (as Charles III, Czech: Karel III.), and the last of the monarchs belonging to the House of Habsburg-Lorraine to rule over Austria-Hungary. The son of Archduke Otto of Austria and Princess Maria Josepha of Saxony, Charles became heir presumptive of Emperor Franz Joseph when his uncle Archduke Franz Ferdinand of Austria was assassinated in 1914. In 1911, he married Princess Zita of Bourbon-Parma. He is venerated in the Catholic Church, was beatified by Pope John Paul II on 3 October 2004, and is known to the Catholic Church as Blessed Karl of Austria.Charles succeeded to the thrones in November 1916 following the death of his grand-uncle, Franz Joseph. He began secret negotiations with the Allies, hoping to peacefully end the First World War, but was unsuccessful. Despite Charles's efforts to preserve the empire by returning it to federalism and by championing Austro-Slavism, Austria-Hungary hurtled into disintegration: Czechoslovakia and the State of Slovenes, Croats and Serbs were proclaimed, and Hungary broke monarchic ties to Austria by the end of October 1918. Following the Armistice of 11 November 1918, Charles "renounced any participation" in government affairs, but did not abdicate. However, the Republic of German-Austria was proclaimed the following day, and in April 1919 the National Assembly formally dethroned the Habsburgs and banished Charles from German-Austria for life.
Charles spent the early part of his exile in Switzerland. He spent the remaining years of his life attempting to restore the monarchy. He made two attempts to reclaim the Hungarian throne in 1921; but failed due to the opposition of Hungary's Calvinist regent Admiral Miklós Horthy. Charles was exiled for a second time to the Portuguese island of Madeira, where he soon fell ill and died of respiratory failure in 1922.
