The title "Prince of Greece and Denmark" refers to a royal title historically held by members of the Greek and Danish royal families. This title was notably held by Prince Philip, Duke of Edinburgh, who was born into the Greek and Danish royal families. The title reflects the historical connections between the two nations and their royal lineages. The title is not currently in active use, as it is tied to specific individuals and their lineage. The Greek monarchy was abolished in 1974, and the Danish monarchy continues to exist, with its own titles and roles within the royal family.
