Dynasties: The Windsors

After King George's death, Prince Edward must choose between the throne and marrying American divorcee, Wallis Simpson.

When the shy, stuttering George VI is crowned King in 1937, he must rebuild the prestige of the monarchy after the shocking abdication of his brother Edward and in the shadow of WWII.

Young Elizabeth II takes her first steps as Queen and is torn between old tradition and those, like her husband, who want to modernise the monarchy.

Prince Charles is next in line to succeed his mother, Queen Elizabeth, and is under great pressure to marry and produce an heir for the Windsor dynasty.

The marriage between the Prince and Princess of Wales starts to fall apart, and the Queen begins to face the greatest challenges of her long reign.

With the marriages of Prince William to Kate Middleton and Prince Harry to Meghan Markle, a new generation re-energises the royal brand, but in the modern media age the pressures of being a royal are more intense than ever.
