The six-part series concludes with a look at the lives of Prince William, Prince Harry, and the future of the crown. With the history-making marriages of Prince William to Kate Middleton and Prince Harry to Meghan Markle, a new generation reenergizes the royal brand, modernizing the Royal Family with more down-to-earth, accessible styles. They extend the Windsor dynasty with families of their own. But, in the modern media age, the pressures of being a royal are more intense than ever. 

Prince Charles and Princess Diana become superstars on the world's stage as their family grows. But, the marriage between the Prince and Princess of Wales starts to fall apart, leading to divorce, and the queen begins to face the greatest challenges of her long reign. In 1997, the world mourns alongside the royal family after Diana is tragically killed in a car crash. 

Prince Charles, next in line to succeed his mother, Queen Elizabeth, is under great pressure to find a wife and produce an heir for the Windsor dynasty. He meets and marries Lady Diana in a grand public wedding, but privately the couple faces serious issues.

Queen Elizabeth II inherits the throne and faces scandals and rumors involving her sister, her marriage, and even her way of leading. The Queen must forge her own path, walking a tightrope between old tradition and those, like her husband, who want to modernize the monarchy.

The shy, stuttering King George VI faces numerous challenges once he takes the throne in 1937: an unstable monarchy, war against Germany, and even his own brother Edward after his shocking abdication. When George VI unexpectedly passes, Princess Elizabeth is thrust into her new role as Queen at the young age of 25.

King George V dies in 1936, and in an unprecedented event, his successor King Edward abdicates the throne—throwing the monarchy into chaos. Edward shocks the people of England by choosing to marry the American divorcee/socialite Wallis Simpson and turning his back on the British empire.
