Fronde, a civil uprising in France in the mid-17th century. There were two phases—the Fronde of the Parliament (1648–49), in which the judicial body called the Parliament of Paris, supported by some of the nobles, opposed the monarchy on taxation; and the Fronde of the Princes (1649–53), in which the nobles opposed the court party in an attempt to overthrow the prime minister, Cardinal Mazarin.

The uprising sprang from the heavy expense of the Thirty Years' War (1618–48), and resentment of Mazarin, actual ruler of France during the boyhood of Louis XIV. Mazarin was the victor. Public disgust with the nobles helped make possible the later absolutism of Louis XIV.

From 1653 to 1659, Spain, which had been in intermittent conflict with France since 1648, supported those nobles still in rebellion. This period of fighting is sometimes referred to as the Spanish Fronde.
