Louis XIV (5 September 1638 – 1 September 1715), also known as Louis the Great (Louis le Grand) or the Sun King (le Roi Soleil), was King of France from 14 May 1643 until his death in 1715. His reign of 72 years and 110 days is the longest recorded of any monarch of a sovereign country in history. His was succeeded by his great-grandson Louis XV (at age 5). Louis XIV's France was emblematic of the age of absolutism in Europe. The King surrounded himself with a variety of significant political, military, and cultural figures, such as Mazarin, Colbert, Louvois, the Grand Condé, Turenne, Vauban, Boulle, Molière, Racine, Boileau, La Fontaine, Lully, Charpentier, Marais, Le Brun, Rigaud, Bossuet, Le Vau, Mansart, Charles Perrault, Claude Perrault, and Le Nôtre.

Louis began his personal rule of France in 1661, after the death of his chief minister, the Cardinal Mazarin. An adherent of the concept of the divine right of kings, Louis continued his predecessors' work of creating a centralised state governed from the capital. He sought to eliminate the remnants of feudalism persisting in parts of France and, by compelling many members of the nobility to inhabit his lavish Palace of Versailles, succeeded in pacifying the aristocracy, many members of which had participated in the Fronde rebellion during his minority. By these means he became one of the most powerful French monarchs and consolidated a system of absolute monarchy in France that endured until the French Revolution. He also enforced uniformity of religion under the Gallican Catholic Church. His revocation of the Edict of Nantes abolished the rights of the Huguenot Protestant minority and subjected them to a wave of dragonnades, effectively forcing Huguenots to emigrate or convert, and virtually destroying the French Protestant community.

During Louis' long reign, France emerged as the leading European power and regularly asserted its military strength. A conflict with Spain marked his entire childhood, while during his reign, the kingdom took part in three major continental conflicts, each against powerful foreign alliances: the Franco-Dutch War, the War of the League of Augsburg, and the War of the Spanish Succession. In addition, France also contested shorter wars, such as the War of Devolution and the War of the Reunions. Warfare defined Louis's foreign policy and his personality shaped his approach. Impelled by "a mix of commerce, revenge, and pique", he sensed that war was the ideal way to enhance his glory. In peacetime he concentrated on preparing for the next war. He taught his diplomats that their job was to create tactical and strategic advantages for the French military.

Significant achievements during his reign which would go on to have a wide influence on the Early Modern Era well into the Industrial Revolution and up to today, include the construction of the Canal du Midi, the creation of the Palace and Gardens of Versailles, the sponsorship and patronage of such artists and composers as Jean-Baptiste de Lully, Molière, and Hyacinthe Rigaud, as well as the founding of the French Academy of Sciences, among others.
