Louis XVI, king of France and later his family, was executed because he wasn`t good as King.
Louis XVI only provoked misfortune to his people; the economy spiraled downward, crops failed, the price of bread and other food soared.
The last straw, was Marie Antoniette his wife. She was their main problem.
So, in January, 1793 Louis XVI`s head rolled off the guillotine and the Bourbon France finished.
