Prince Phillip, the Duke of Edinburgh and the husband to Queen Elizabeth for more than 70 years died on Friday at the age of 99. He had dedicated his life to supporting her and the country.

The prince was of royal blood. He was the great-great-grandchild of Queen Victoria. His father, Prince Andrew of Greece, was the younger brother of the King Constantine of Greece. His mother was a descendant of German princes. His father was an Army commander during the Greco-Turkish War and was forced into exile in France after his defeat at the hands of the Turks in 1922.

Prince Phillip was educated in Britain and entered Britannia Royal Naval College Dartmouth as a cadet in 1939. During World War II, he served on the HMS Ramillies and the HMS Valiant shortly afterward. Later, the prince was transferred to HMS Wallace, a WWI destroyer that was converted to an anti-aircraft escort ship.

The prince served with distinction as a searchlight officer in action against the Italian Navy. He was praised in dispatches for his contributions to the Battle of Cape Matapan, during which allied forces sank five enemy vessels and killed over 2,000 enemy sailors. Later taking part in the shelling of Tripoli he was decorated for bravery.

Prince Phillip was promoted after the Battle of Crete. Transferred to the Pacific, he was among the allied officers present for the Japanese surrender in Tokyo Bay

After the war, he met and married then-Princess Elizabeth and continued his naval career. Initially, he met with disapproval from many in the U.K. as he was a Greek by birth. But eventually, this disapproval dissipated. 

When King George died of cancer in 1952 and Elizabeth became queen, Prince Phillip was forced to leave behind his naval career, although he had recently been promoted to the rank of commander. 

As the official consort to the Queen, he had to come up with things to do. There was no official playbook for Prince Phillip to follow. It was a dilemma for both the prince and the staff at the palace.
