The French Renaissance and the beginning of the Ancien Régime, normally marked by the reign of Francis I, saw the nation become far more unified under the monarch. The power of the nobles was diminished as a national army was created. With England expelled from the continent and being consumed by the Wars of the Roses, France’s main rival was the Holy Roman Empire. This threat to France became alarming in 1516 when Charles V became the king of Spain, and grew worse when Charles was also elected Holy Roman Emperor in 1519. France was all but surrounded as Germany, Spain, and the Low Countries were controlled by the Habsburgs. The lengthy Italian Wars that took place during this period eventually resulted in defeat for France and established Catholic Spain, which formed a branch of the Habsburg holdings, as the most powerful nation in Europe, with their dreaded tercios dominating the European battlefield well into the Thirty Years War. Later in the 16th century, France was weakened internally by the Wars of Religion. As nobles managed to raise their private armies, these conflicts between Huguenots and Catholics all but demolished centralization and monarchical authority, precluding France from remaining a powerful force in European affairs. On the battlefield, the religious conflicts highlighted the influence of the gendarmes, heavy cavalry units that comprised the majority of cavalrymen attached to the main field armies. The pride of the royal cavalry, gendarme companies were often attached to the main royal army in hopes of inflicting a decisive defeat on Huguenot forces, although secondary detachments were also used for scouting and intercepting enemy troops.

After the Wars of Religion, France could do little to challenge the dominance of the Holy Roman Empire, although the empire itself faced several problems. From the east, it was facing intense warfare against the Ottoman Empire, with which France allied. The vast Habsburg empire also proved impossible to manage effectively, and the crown was soon divided between the Spanish and Austrian holdings. In 1568, the Dutch declared independence, launching a war that would last for decades and would illustrate the weaknesses of Habsburg power. In the 17th century, the religious violence that had beset France a century earlier began to tear the empire apart. At first France sat on the sidelines, but under Cardinal Richelieu it saw an opportunity to advance its interests at the expense of the Habsburgs. Despite France’s staunch Catholicism, it intervened on the side of the Protestants. The Thirty Years’ War was long and extremely bloody, but France and its allies came out victorious, under the leadership of the legendary commanders Condé and Turenne, beginning a long line of unparalleled French marshals who would help usher in a new era of military strategy. After their victory, France emerged as the sole dominant European power under the reign of Louis XIV. In parallel, French explorers, such as Jacques Cartier or Samuel de Champlain, claimed lands in the Americas for France, paving the way for the expansion of the French colonial empire.

The long reign of Louis XIV saw a series of conflicts: the War of Devolution, the Franco-Dutch War, the War of the Reunions, the Nine Years War, and the War of the Spanish Succession. Few of these wars were either clear victories or definite defeats, but French borders expanded steadily anyway. The west bank of the Rhine, much of the Spanish Netherlands, and a good deal of Luxembourg were annexed while the War of the Spanish Succession saw the grandson of Louis placed on the throne of Spain. The French strategic situation, however, changed decisively with the Glorious Revolution in England, which replaced a pro-French king with an enemy of Louis, the Dutch William of Orange. After two centuries seeing only rare hostilities with France, England now became a consistent enemy again, and remained so until the 19th century. To stop French advances, England formed coalitions with several other European powers, most notably the Habsburgs. While these armies had difficulties against the French on land, the British Royal Navy dominated the seas, and France lost many of its colonial holdings. The British economy also became Europe’s most powerful, and British money funded the campaigns of their continental allies.

Wars in this era consisted mostly of sieges and movements that were rarely decisive, prompting the French military engineer Vauban to design an intricate network of fortifications for the defense of France. The armies of Louis XIV were some of the most impressive in French history, their quality reflecting military and political developments. In the mid-17th century, royal power reasserted itself and the army became a tool through which the King could wield authority, replacing older systems of mercenary units and the private forces of recalcitrant nobles. Military administration also made gigantic progress as food supply, clothing, equipment, and armaments were provided in a regularity never before equaled. The French embedded this standardization by becoming the first army to give their soldiers national uniforms in the 1680s and 1690s.

The 18th century saw France remain the dominant power in Europe, but begin to falter largely because of internal problems. The country engaged in a long series of wars, such as the War of the Quadruple Alliance, the War of the Polish Succession, and the War of the Austrian Succession, but these conflicts gained France little. Meanwhile, Britain’s power steadily increased, and a new force, Prussia, became a major threat. This change in the balance of power led to the Diplomatic Revolution of 1756, when France and the Habsburgs allied after centuries of animosity. This alliance proved less than effective in the Seven Years’ War, but in the American Revolutionary War, the French helped inflict a major defeat on the British.
