Which of Queen Victoria's sons became Duke of Edinburgh?

Prince Alfred became Duke of Edinburgh, making him the correct answer. He was Queen Victoria and Prince Albert’s second son, born at Windsor Castle in 1844, and pursued a long career in the Royal Navy.

Alfred was created Duke of Edinburgh in 1866, during his mother’s reign. The title reflected his naval importance and distinguished him from his elder brother Albert Edward, who was Prince of Wales and later King Edward VII.

In 1874, Alfred married Grand Duchess Maria Alexandrovna of Russia. He later inherited the ducal throne of Saxe-Coburg and Gotha in 1893, becoming Alfred, Duke of Saxe-Coburg and Gotha, while retaining his British title.

A common mix-up is with Prince Philip, who became Duke of Edinburgh in the twentieth century. Philip was Queen Victoria’s great-great-grandson, not her son. Among Queen Victoria’s own sons, Alfred was the one who held the title Duke of Edinburgh.
