Episode 5

A look at how George V's ascension to the throne in 1910 led to the birth of the House of Windsor. JJ Chalmers discovers how the highly traditional king and Queen Mary were sticklers for stuffy royal etiquette - enforcing a strict dress code and dining with bizarrely outdated formality. Alexander reveals how the First World War made the bombing of Buckingham Palace a very real possibility, so the lake in the garden was drained in an extraordinary effort to make it more difficult for enemy planes to spot.
