What was the name of wife of King Louis XVI?
Louis XVI was a famous French king back in the 1780's. He was the king in the French Revolution. His wife was Marie Antoinette. She was actually Austrian. She married Louis XVI as a young lady, and her country was furious with her. She was more worried about fashion than her dying country. They were both executed by a guillotine.
This is confusing. King Louis XVI was the monarch, since a monarch is a king. If you are asking what influence King Louis XVI had on the monarchy, you may be getting confused with King Louis XIV, his ancestor. Louis XVI's influence on the monarchy was to have it abolished, as he was King during the French Revolution.
