Answer
Louis, Grand Condé, led the second Fronde against Cardinal Mazarin. The Fronde was a series of uprisings against the French monarchy during the regency of Anne of Austria. The second Fronde, which took place from 1650 to 1653, was led by Condé and other nobles who were dissatisfied with Mazarin's policies. The Frondeurs were eventually defeated by the royal army, and Condé was forced to flee France.
