The marriage of Prince Harry and Meghan Markle, when the second son of
the Prince of Wales married a divorced American actress of mixed race and
uncertain religion, was seen as a fundamental modernisation of the British
monarchy.

Historian and presenter David Starkey (Radio 4’s Moral Maze, Question Time)
traces the radically shifting marriage customs of the British monarchy, from
the laxity of the Middle Ages, through the stringencies of the Hanoverians,
to the house of Windsor and its sometimes contorted adaptations to the
realities of modern family life.
