Frederick III, German Emperor
Frederick III (18 October 1831 – 15 June 1888) was German Emperor and King of Prussia for ninety-nine days in 1888, the Year of the Three Emperors.
Known informally as "Fritz", he was the only son of Emperor Wilhelm I and was raised in his family's tradition of military service.
Although celebrated as a young man for his leadership and successes during the Second Schleswig, Austro-Prussian and Franco-Prussian wars, he nevertheless professed a hatred of warfare and was praised by friends and enemies alike for his humane conduct.
Following the unification of Germany in 1871 his father, then King of Prussia, became the German Emperor.
Upon Wilhelm's death at the age of ninety on 9 March 1888, the thrones passed to Frederick, who had by then been German Crown Prince for seventeen years and Crown Prince of Prussia for twenty-seven years.
Frederick was suffering from cancer of the larynx when he died, aged fifty-six, following unsuccessful medical treatments for his condition.
Frederick married Victoria, Princess Royal, eldest daughter of Queen Victoria of the United Kingdom.
The couple were well-matched; their shared liberal ideology led them to seek greater representation for commoners in the government.
Frederick, in spite of his conservative militaristic family background, had developed liberal tendencies as a result of his ties with Britain and his studies at the University of Bonn.
As the Crown Prince, he often opposed the conservative Chancellor Otto von Bismarck, particularly in speaking out against Bismarck's policy of uniting Germany through force, and in urging that the power of the Chancellorship be curbed.
Liberals in both Germany and Britain hoped that as emperor, Frederick III would move to liberalize the German Empire.
Frederick and Victoria were great admirers of Prince Albert, Queen Victoria's husband.
They planned to rule as consorts, like Albert and Queen Victoria, and to reform what they saw as flaws in the executive branch that Bismarck had created for himself.
The office of Chancellor, responsible to the Emperor, would be replaced with a British-style cabinet, with ministers responsible to the Reichstag.
Government policy would be based on the consensus of the cabinet.
Frederick "described the Imperial Constitution as "ingeniously contrived chaos.
According to Michael Balfour:
However, Frederick's illness prevented him from effectively establishing policies and measures to achieve this, and such moves as he was able to make were later abandoned by his son and successor, Wilhelm II.
The timing of Frederick's death and the length of his reign are important topics among historians.
His premature demise is considered a potential turning point in German history; and whether or not he would have made the Empire more liberal if he had lived longer is still discussed.
Princess Charlotte of Prussia (1831–1855)
Princess Charlotte of Prussia( 21 June 1831 – 30 March 1855), was by birth a Princess of Prussia and member of the House of Hohenzollern and by marriage Hereditary Princess of Saxe- Meiningen.

Sophia of Prussia
Sophia of Prussia ("Sophia Dorothea Ulrike Alice"; 14 June 1870 – 13 January 1932) was Queen consort of Greece during 1913–1917 and 1920–1922.
A member of the House of Hohenzollern and daughter of Frederick III, German Emperor, Sophia received a liberal and anglophile education, under the supervision of her mother, Victoria, Princess Royal.
In 1889, less than a year after the death of her father, she married her third cousin Constantine, heir apparent to the Greek throne.
After a difficult period of adaptation in her new country, Sophia gave birth to six children and became involved in the assistance to the poor, following in the footsteps of her mother-in-law, Queen Olga.
However, it was during the wars which Greece faced during the end of the 19th and the beginning of the 20th century that Sophia showed the most social activity: she founded field hospitals, oversaw the training of Greek nurses, and healed wounded soldiers.
However, Sophia was hardly rewarded for her actions, even after her grandmother Queen Victoria decorated her with the Royal Red Cross after the Thirty Days' War: the Greeks criticized her links with Germany.
Her brother Emperor William II was indeed an ally of the Ottoman Empire and openly opposed the construction of the "Megali Idea", which could establish a Greek state that would encompass all ethnic Greek-inhabited areas.
During World War I, the blood ties between Sophia and the German Emperor also aroused the suspicion of the Triple Entente, which criticized Constantine I for his neutrality in the conflict.
After imposing a blockade of Greece and supporting the rebel government of Eleftherios Venizelos, causing the National Schism, France and its allies deposed Constantine I in June 1917.
Sophia and her family then went into exile in Switzerland, while the second son of the royal couple replaced his father on the throne under the name of Alexander I.
At the same time, Greece entered the war alongside the Triple Entente, which allowed it to grow considerably.
After the outbreak of the Greco-Turkish War in 1919 and the untimely death of Alexander I the following year, the Venizelists abandoned power, allowing the royal family's return to Athens.
The defeat of the Greek army against the Turkish troops of Mustafa Kemal, however, forced Constantine I to abdicate in favor of his eldest son George II in 1922.
Sophia and her family then were forced to a new exile, and settled in Italy, where Constantine died one year later (1923).
With the proclamation of the Republic in Athens (1924)
Sophia spent her last years alongside her family and died of cancer in Germany in 1932.
