Marie Antoinette was only 14 when she was sent to France from Austria. She didn't speak French. Louis XVI was only 16. He was a book nerd who didn't like his new wife. They rarely interacted at first until he became king of France at the age of 20.

She was bored most of the time and not socially aware of what the French were going through when Jews started buying up all of the available grain and storing it in warehouses then watering it so it would go bad. She had friends and for a very short period she and her friends had competitions to see who can do their hair up the highest.

This was not a regular thing she did, just for a few days in her early 20s, but she is almost always depicted with a ridiculous hair style in every image of her after that.

Eventually she and Louis got along and had kids (after many years of celibacy).

After the Jews created an artificial famine and blamed the royal family for it the people of France turned against them.

They were publicly executed as we know. Quite literally they didn't do anything wrong but nobody at the time believed it. Marie accidentally stepped on her executioner's foot and apologized to him before he cut her head off.

After the royal family was snuffed out the Jews ("Jacobin Leftists") convinced the people to allow the beheading of 200,000 innocent blond-haired blue-eyed Christians just because.

King Louis' son King Louie XVII was imprisoned and tortured for two years, beaten, starved, made to sleep on cold ground, sexually assaulted, and eventually beaten to death (the official story is that he died of TB). He died at the age of 10 thus ending the French monarchy so the Jacobins could install "Democracy" in France and then move on to destroy all royalty in Europe.
