In France when the monarchy was still well established, it was tradition to let many spectators watch the queens give birth to their children.
The idea behind all of this was to prove that the children are legitimate. In the case of the famous (later beheaded) Queen Marie Antoinette (1755–1793), so many people rushed into her chamber that she almost got squeezed to death. Not a nice way to give birth. Not that there IS a nice way, but this is even worse…
