Napoleon Bonaparte

If yes, by who?

I disagree, Britain had no need to poison him. He was their prisoner and totally under their control. And when you have an ace in your hand you don't disgard it.

Modern researchers tend to go to French royalists who were worried Britain may use him as a bargaining chip against them, were worried by discontent in the country in his name and just plain frightened he'd make another comback.

His food was prepared by his own cooks and there's been much speculation one of his servants may have been a royalist spy.

so do I, I tend not to jump for such theories unless I can see some real proof.

If he was poisened though, Paul is right, its more likely a Frenchman than a Briton behind it.

No, I don't think he was murdered. He wrote in his will that he was poisoned but many people say foolish things when they think they are going to die. Also, he was in exile for six years when he died and he was out of shape, so why would the British kill him when he wasn't a threat anymore.

And his father Carlo died of the same thing. The doctor concluded that it was stomach cancer without knowing that.
