Led by King Louis XIV, the French army invaded the Spanish Netherlands, beginning the War of Devolution.

Louis XIV, also known as Louis the Great or the Sun King, was King of France from 1643 until his death in 1715. His verified reign of 72 years and 110 days is the longest of any monarch in history. An emblem of the age of absolutism in Europe, Louis XIV's legacy includes French colonial expansion, the conclusion of the Thirty Years' War involving the Habsburgs, and a controlling influence on the style of fine arts and architecture in France, including the transformation of the Palace of Versailles into a center of royal power and politics. Louis XIV's pageantry and opulence helped define the French Baroque style of art and architecture and promoted his image as supreme leader of France in the early modern period.

The Spanish Netherlands were a collection of States of the Holy Roman Empire in the Low Countries, held in personal union by the Spanish Habsburgs, but not annexed to the Spanish Crown, thus encompassing the second period in history of the Habsburg Netherlands, that lasted from 1556 to 1714. This region comprised most of the modern states of Belgium and Luxembourg, as well as parts of northern France, the southern Netherlands, and western Germany, with the capital being Brussels. The Army of Flanders was given the task of defending the territory.

The War of Devolution took place from May 1667 to May 1668. In the course of the war, France occupied large parts of the Spanish Netherlands and Franche-Comté, both then provinces of the Holy Roman Empire ruled by Spain. Its name derives from an obscure law known as the Jus Devolutionis, used by Louis XIV to claim that these territories had "devolved" to him by right of marriage to Maria Theresa of Spain.
