Answer: Europe wanted to put Louis XVI back in power.
Step-by-step explanation:
In 1791 as the French Revolution was in its early days, Louis XVI and his wife Marie Antoinette were captured as they attempted to flee to Austria. They were imprisoned the following year whereupon the National Convention now under the control of Radicals abolished the monarchy.
A year after the imprisonment Louis was executed for treason on the orders of the Radicals who were angry that Austria, Prussia and other European powers wanted to put him back on the throne and so eliminated him to prevent it.
