his mother was the eldest daughter of King Christian IX and Queen Louise of Denmark. He was baptised at Windsor Castle on 7 July 1865 by the Archbishop of Canterbury, Charles Longley.
As a younger son of the Prince of Wales, there was little expectation that George would become king. He was third in line to the throne, after his father and elder brother, Prince Albert Victor.
George was only 17 months younger than Albert Victor, and the two princes were educated together. John Neale Dalton was appointed as their tutor in 1871. Neither Albert Victor nor George excelled intellectually. As their father thought that the navy was "the very best possible training for any boy", in September 1877, when George was 12 years old, both brothers joined the cadet training ship HMS Britannia at Dartmouth, Devon.
For three years from 1879, the royal brothers served on HMS Bacchante, accompanied by Dalton. They toured the colonies of the British Empire in the Caribbean, South Africa and Australia, and visited Norfolk, Virginia, as well as South America, the Mediterranean, Egypt, and East Asia. In 1881 on a visit to Japan, George had a local artist tattoo a blue and red dragon on his arm, and was received in an audience by the Emperor Meiji; George and his brother presented Empress Haruko with two wallabies from Australia. Dalton wrote an account of their journey entitled The Cruise of HMS Bacchante. Between Melbourne and Sydney, Dalton recorded a sighting of the Flying Dutchman, a mythical ghost ship. When they returned to Britain, the Queen complained that her grandsons could not speak French or German, and so they spent six months in Lausanne in an ultimately unsuccessful attempt to learn another language. After Lausanne, the brothers were separated; Albert Victor attended Trinity College, Cambridge, while George continued in the Royal Navy. He travelled the world, visiting many areas of the British Empire. During his naval career he commanded Torpedo Boat 79 in home waters, then HMS Thrush on the North America and West Indies Station. His last active service was in command of HMS Melampus in 1891–92. From then on, his naval rank was largely honorary.
As a young man destined to serve in the navy, Prince George served for many years under the command of his uncle, Prince Alfred, Duke of Edinburgh, who was stationed in Malta. There, he grew close to and fell in love with his cousin, Princess Marie of Edinburgh. His grandmother, father and uncle all approved the match, but his mother and aunt—the Princess of Wales and Maria Alexandrovna, Duchess of Edinburgh—opposed it. The Princess of Wales thought the family was too pro-German, and the Duchess of Edinburgh disliked England. The Duchess, the only daughter of Alexander II of Russia, resented the fact that, as the wife of a younger son of the British sovereign, she had to yield precedence to George's mother, the Princess of Wales, whose father had been a minor German prince before being called unexpectedly to the throne of Denmark. Guided by her mother, Marie refused George when he proposed to her. She married Ferdinand, the future King of Romania, in 1893.
In November 1891, George's elder brother, Albert Victor, became engaged to his second cousin once removed Princess Victoria Mary of Teck, known as "May" within the family. Her parents were Francis, Duke of Teck (a member of a morganatic, cadet branch of the House of Württemberg), and Princess Mary Adelaide of Cambridge, a male-line granddaughter of King George III and a first cousin of Queen Victoria.
On 14 January 1892, six weeks after the formal engagement, Albert Victor died of pneumonia during an influenza pandemic, leaving George second in line to the throne, and likely to succeed after his father. George had only just recovered from a serious illness himself, after being confined to bed for six weeks with typhoid fever, the disease that was thought to have killed his grandfather Prince Albert. Queen Victoria still regarded Princess May as a suitable match for her grandson, and George and May grew close during their shared period o
