What did Marie Antoinette and King Louis do in 1773?

Answer 1

I believe...1 sec...let me look at my notes here...Well, what got them killed was that were on the brink of sending the country into bankruptsy (pardon my spelling!), and couldn't save the country from inflation, unemployment, poor harvests, food shortages, or the rising prices that were tormenting the entire country. But after Louis summoned the National Assembly, word leaked out that he had planned to bring in troops to arrest the assembly.

Answer 2

They were imprisoned because the Legislative Assembly declared war on Austria/Prussia.

They where beheaded because they tried to escape France.
