What is the Origin of napoleon cake?

I'm going to have to say France, because of Napoleon Bonaparte. He was also the king of France Emperor of France during the French and Indian War. I'm pretty sure he also sold the USA, the Louisiana Purchase.

True, the cake did originate in France. But not because of Napoleon Bonaparte. The French call the cake Mille-Fueille, which means "thousand leaf." It is also called the vanilla-slice, cream-slice, and custard-slice in the UK.

The cake originated from France in 1651, which was nearly 100 years before Bonaparte was even born. This clearly proves Napoleon had nothing to do with the naming of the cake, or even its origination (which is still unknown, save for where and when. As for who made it originally, no one knows).
