King of Greece in the context of "Alexander of Greece"

Otto I (Greek: Όθων, romanized: Óthon; German: Otto Friedrich Ludwig von Wittelsbach; 1 June 1815 – 26 July 1867) was King of Greece from the establishment of the Kingdom of Greece on 7 May 1832, under the Convention of London, until he was deposed in October 1862.

The second son of King Ludwig I of Bavaria, Otto ascended the newly created throne of Greece at age 17. His government was initially run by a three-man regency council made up of Bavarian court officials. Upon reaching his majority, Otto removed the regents when they proved unpopular with the people, and he ruled as an absolute monarch. Eventually, his subjects' demands for a constitution proved overwhelming, and in the face of an armed (but bloodless) insurrection, Otto granted a constitution in 1843.

George I (Greek: Γεώργιος Α΄, romanized: Geórgios I; 24 December 1845 – 18 March 1913) was King of Greece from 30 March 1863 until his assassination on 18 March 1913.

Originally a Danish prince, George was born in Copenhagen, and seemed destined for a career in the Royal Danish Navy. He was only 17 years old when he was elected king by the Greek National Assembly, which had deposed the unpopular King Otto. His nomination was both suggested and supported by the Great Powers: the United Kingdom of Great Britain and Ireland, the Second French Empire and the Russian Empire. He married Grand Duchess Olga Constantinovna of Russia in 1867, and became the first monarch of a new Greek dynasty. Two of his sisters, Alexandra and Dagmar, married into the British and Russian royal families. Edward VII of the United Kingdom and Alexander III of Russia were his brothers-in-law, and George V of the United Kingdom, Christian X of Denmark, Haakon VII of Norway, and Nicholas II of Russia were his nephews.

Constantine II (Greek: Κωνσταντίνος Βʹ, romanized: Konstantínos II, pronounced [ˌkonsta(n)ˈdinos o ˈðefteros]; 2 June 1940 – 10 January 2023) was the last King of Greece, reigning from 6 March 1964 until the abolition of the Greek monarchy on 1 June 1973.

Constantine was born in Athens as the only son of Crown Prince Paul and Crown Princess Frederica of Greece. Being of Danish descent, he was also born as a prince of Denmark. As his family was forced into exile during the Second World War, he spent the first years of his childhood in Egypt and South Africa. He returned to Greece with his family in 1946 during the Greek Civil War. After Constantine's uncle, George II, died in 1947, Paul became the new king and Constantine the crown prince. As a young man, Constantine was a competitive sailor and Olympian, winning a gold medal in the 1960 Rome Olympics in the Dragon class along with Odysseus Eskitzoglou and George Zaimis in the yacht Nireus. From 1964, he served on the International Olympic Committee.

Pavlos, Crown Prince of Greece, Prince of Denmark (Greek: Παύλος Ντε Γκρες, romanized: Pavlos de Grèce; born 20 May 1967), is a Greek financier who is the former heir apparent to the defunct throne of Greece, becoming the Head of the Royal House of Greece upon his father's death on 10 January 2023. Pavlos was Crown Prince of Greece and heir apparent to the Greek throne from birth until the monarchy's abolition.

Pavlos was born in Athens as the second child and eldest son of the last King of Greece, Constantine II, and his wife Queen Anne-Marie. Pavlos was born into an unstable era for Greek politics, just shy of turning eight months old when he and his family were sent into exile, after Constantine II staged a failed counter-coup against the military junta. They first lived in Rome, before eventually settling in Copenhagen, where his family lived with Pavlos's maternal grandparents, King Frederik IX and Queen Ingrid of Denmark. Although they were in exile since December 1967, his parents continued to officially reign as King and Queen of the Hellenes from 1967 until 1973, when the military junta abolished the Greek monarchy and established the Third Hellenic Republic as its successor state. Following the abolition of the monarchy, Pavlos and his siblings grew up in London.

Paul (Greek: Παύλος, romanized: Pavlos; 14 December 1901 – 6 March 1964) was King of Greece from 1 April 1947 until his death on 6 March 1964.

Paul was born in Athens as the third son of Crown Prince Constantine and Crown Princess Sophia of Greece. In 1912, the year before his father ascended the throne, Paul joined the Royal Hellenic Navy at eleven years old, becoming the youngest cadet at the time. After the National Schism during World War I, Constantine's abdication was forced and Paul and his family went into exile in Switzerland. Paul's brother, Alexander, became the Greek sovereign in 1917 when Constantine and Paul were exiled, however, Alexander's death in 1920 led to Constantine's restoration. In 1922, Paul's other brother, George, became the monarch. However, a referendum in 1924 two years later saw the abolition of the Greek monarchy. Paul moved to Italy with his family and then to London.

Alexandra of Denmark (Alexandra Caroline Marie Charlotte Louise Julia; 1 December 1844 – 20 November 1925) was Queen of the United Kingdom and the British Dominions, and Empress of India, from 22 January 1901 to 6 May 1910 as the wife of King Edward VII.

Alexandra's family had been relatively obscure until 1852, when her father, Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, was chosen (with the consent of the major European powers) to succeed his second cousin Frederick VII as King of Denmark. At the age of 16, she was chosen as the future wife of Albert Edward, Prince of Wales, the son and heir apparent of Queen Victoria. The couple married 18 months later in 1863, the year in which her father became king of Denmark as Christian IX and her brother William was appointed king of Greece as George I.

Constantine I (Greek: Κωνσταντίνος Αʹ, romanized: Konstantínos I; 2 August [O.S. 21 July] 1868 – 11 January 1923) was King of Greece from 18 March 1913 to 11 June 1917 and again from 19 December 1920 to 27 September 1922. The eldest son of George I of Greece, he succeeded to the throne following his father's assassination in 1913.

Educated in Greece and later in Germany, Constantine was an admirer of Prussian militarism. As the crown prince, he was commander-in-chief of the Hellenic Army during the unsuccessful Greco-Turkish War of 1897. Later and under the leadership of Prime Minister Eleftherios Venizelos, he led successfully the Greek forces in the Balkan Wars of 1912–1913, in which Greece expanded, doubling in area and population.

George II (Greek: Γεώργιος Β', romanized: Geórgios II; 19 July [O.S. 7 July] 1890 – 1 April 1947) was King of Greece from 27 September 1922 until 25 March 1924, and again from 25 November 1935 until his death on 1 April 1947.

The eldest son of King Constantine I of Greece and Princess Sophia of Prussia, George followed his father into exile in 1917 following the National Schism, while his younger brother Alexander was installed as king. Constantine was restored to the throne in 1920 after Alexander's death, but was forced to abdicate two years later in the aftermath of the Greco-Turkish War. George acceded to the Greek throne, but after a failed royalist coup in October 1923 he was exiled to Romania. Greece was proclaimed a republic in March 1924 and George was formally deposed and stripped of Greek nationality. He remained in exile until the Greek monarchy was restored in 1935, following a rigged referendum, upon which he resumed his royal duties. The king supported Ioannis Metaxas' 1936 self-coup, which established an authoritarian, nationalist and anti-communist dictatorship known as 4th of August Regime.
