Paul (Greek: Παῦλος, Βασιλεὺς τῶν Ἑλλήνων, Pávlos, Vasiléfs ton Ellínon) reigned as King of Greece from 1947 until his death.
Paul was born in Athens, the third son of King Constantine I of Greece and his wife, Princess Sophia of Prussia. He trained as an army officer at the Royal Military College, Sandhurst and later at the Hellenic Military Academy in Kypseli, Athens. Paul was an army officer cadet in the Coldstream Guards and Lieutenant with the Evzones.
From 1917 to 1920, Paul lived in exile with his father, Constantine I. From 1923 to 1935, he lived in exile again in England, this time with his brother, George II. Paul returned to Greece in 1946. He succeeded to the throne in 1947, on the death of his childless elder brother, King George II, during the Greek Civil War (between Greek Communists and the non-communist Greek government).
King Paul was styled "Βασιλεύς τῶν Ἑλλήνων" (King of the Hellenes).
