Princess Märtha of Sweden
During the 1928 Summer Olympics in Amsterdam, Princess Märtha of Sweden became engaged to her first and second cousin, Prince Olav, only son and heir apparent of her uncle the King of Norway and grandson of her grandfather King Frederick VIII of Denmark's younger sister. News of the engagement was very well received. An excellent match for strengthening royal ties, it was also clearly a match based on love. Initially, her younger sister, Astrid, was expected to marry Olav, being younger than Olav by two years, while Märtha was two years older. Astrid was also considered more beautiful, but she instead married the future King of the Belgians Leopold III.
