The best I can come up with is Louis Capet, a Bourbon prince born on VE day. This association with the start of a new era becomes part of his mystique later. He grows up to be an extremely popular, charismatic, and politically clever young man by his early twenties. He may or may not be technically first in the line of succession, but he is the public face of the house of Bourbon when the crisis of 1968 arrives. He is the same generation as the young revolutionaries, and has all the establishment contacts that come with his family background. A new slogan is heard on the streets, "Louis, Roi de France".
Could anyone familiar with the details of 1968 tell me how feasible this is?
