Final answer:
Émigrés were the nobles that left France before the Reign of Terror. They sought refuge in other countries and hoped to restore the old monarchy.
Step-by-step explanation:
The nobles that left France before the Reign of Terror were called Émigrés. During the French Revolution, many nobles who opposed the revolution or feared for their safety chose to leave France and seek refuge in other countries. These Émigrés hoped to restore the old monarchy and regain their privileges and power that they held under the old French order. However, their return and attempt to reclaim their lands and privileges created distrust and unrest among the middle and lower classes.
