Poor Marie Antoinette has really received a bad rap in revolutionary history. In this compelling new revisionist biography, MARIE ANTOINETTE: The Journey (Doubleday, $35, MP $28), Antonia Fraser has written a lively and sympathetic account of a child-princess sent off to a foreign land to wed an ungainly and ugly king she had never met. Surprisingly compassionate, Marie Antoinette was unfairly vilified and beheaded by revolutionaries whose zeal far outstripped their understanding of the true nature of the Queen.

What if, somehow, she and Louis XVII survived; her husband still gets executed, but she and her son escape, and the Bourbons are restored to the throne with her as regent. What would Napoleon do?

What if, in addition to their survival, Napoleon never becomes prominent?

It's easy to guess that the young Louis might be a reformer. How much would women's rights advance because of Marie Antoinette?

The Spanish might hold onto Louisiana, but the US invades it by 1812, or the US buys it from Spain.

The butterfly effect does away with the Burr-Hamilton duel; he could have been elected President.

Any other ideas? Or is this too unlikely?

If she had made it back to Austria-Hungary I think she would have been able to get her brother, Joseph II, to invade France. France would have come back under the perview of the Hapsburgs. Nappy would have been sent to the most remote part of the empire.

How about making them flee to Lousiana and allow the Spanish to let them set up a state corresponding to the borders of the OTL US State of Louisiana? That would be interesting...
