Thats true, our line of kings come from a mediocre french general. Napoleon gav his go-ahead to Bernadotte becoming the new swedish king on the condition that he would'nt ever start war with france. Bernadotte said a diplomatic version of "up yours" and later did. But he's not our ruler, more like advertisement and a link with history
There are many english myths about france, manly I think because they historically always was there main adversary and england won. But there was
a time when napolenons armies were unstoppable and all of europe had to
confront france to stop him, kinda like hitler a bit - without the sinister stuf.
...and napoleon was not short by comparison to the general public - thats another english propaganda-myth.
