Paul lived in London from 1919 to 1924 and only infrequently visited Belgrade. During his time in London, he was the proverbial "life of the party" who enjoyed socialising with the British elite at parties in London or in various country houses.[ On October 22, 1923, he married Princess Olga of Greece and Denmark, a sister of Princess Marina, Duchess of Kent. The Duke of York (the future King George VI), was the best man at his wedding in Belgrade.
In 1939, Prince Paul, as acting head of state, accepted an official invitation from Adolf Hitler and spent nine days in Berlin. During his visit to Berlin, a massive effort was made to persuade Paul to not join the "peace front" that was meant to "contain" Germany.[ Paul was greeted by Hitler at the train station in Berlin, was made the guest of honor at a reception and dinner at the Reich Chancellery, visited the Potsdam military base, saw a gala performance of Wagner at the Berlin opera, and reviewed two major military parades meant to impress upon him the power of the Reich.

Princess Olga of Greece and Denmark (Greek: Όλγα; 11 June 1903 – 16 October 1997) was a Greek princess who married Prince Paul, Regent of the Kingdom of Yugoslavia. After her marriage, she was known as Princess Paul of Yugoslavia12. Princess Olga's life was imbued with drama from childhood. She was taken 'hostage' by her Romanov grandmother and was further traumatised by the assassination of her grandfather, the King of Greece.
