King Charles and Princess Diana had only met each other 13 times before they got married. They met for the first time when Diana was just 16 years old, and Charles was 29, while they were attending a country weekend at a friend’s house in July 1979. They reportedly saw each other only occasionally over the next few years, but in 1981, they began to date seriously and announced their engagement later that same year. Despite their limited time together before their marriage, the royal wedding was watched by millions of people around the world and remains one of the most iconic moments in modern British history.
