France's Ascendancy: A Result of the Thirty Years' War
The Thirty Years' War began as a religious conflict between Catholics and Protestants within the Holy Roman Empire. Notably, the Holy Roman Empire was comprised of modern-day Germany, Austria, Belgium, Luxembourg, the Netherlands, Czech Republic, Switzerland, Liechtenstein, substantial parts of Italy, and sections of France, Denmark, and Poland.
The Catholic Habsburgs, who ruled the empire, were opposed by Protestant princes and the kingdoms of Denmark, Sweden, and Catholic France, which started as a religious war soon turned into a broader political struggle over the power and structure of the Holy Roman Empire. The Catholic Habsburgs and their allies fought against the Protestant princes and the foreign powers that supported them. It was, one of the most destructive conflicts in European history, spanned from 1618 to 1648. This brutal war not only reshaped the political landscape of Europe but also left a legacy that resonates with geopolitical implications even today.

While the war had no definitive victor, France emerged as the most significant beneficiary. The Peace of Westphalia (24 October 1648) allowed France to gain territory and political influence, setting the stage for its dominance in European affairs in the resulting centuries. The Holy Roman Empire and the Habsburgs, despite retaining their positions, saw their influence considerably weakened. This article will explore how the Peace of Westphalia reshaped the political landscape of Europe, with France emerging as a leading force on the continent.

Martin Luther's Reformation: A Challenge to Catholicism
The Protestant Reformation began on October 31, 1517 when Martin Luther (often called the father of Protestantism), a German theologian and religious reformer, published his "95 Theses" criticizing the Catholic Church. It led to the creation of new Christian groups like Lutheranism and Calvinism. The movement's influence persisted through the 16th and 17th centuries, with the Thirty Years' War (1618-1648) marking a significant turning point that paved the fragmentation of Western Christianity. The Peace of Westphalia, signed on 24 October 1648, is the most commonly mentioned terminuses of the Protestant Reformation era in Europe.
Luther's intention was not to create a completely new branch of Christianity, but rather to fix the problems he saw in the Catholic Church. However, his actions had much larger consequences than he anticipated. By translating the Bible into the German language, Luther made the scriptures accessible to the general population, sparking widespread debate and questioning of Catholic theology and authority.
Suddenly, ordinary people could read and interpret the Bible for themselves, without having to rely on the Catholic clergy. This challenged the moral and spiritual leadership of the Pope, as more and more Christians began to doubt the Church's teachings and practices. What started as one man's effort to reform the Church ultimately led to a full-blown religious revolution - the Protestant Reformation - that would transform the religious and political landscape of Europe for centuries to come.
Prelude of the War: Rise of Protest States & Politics of the House of Bourbon
The Thirty Years' War was primarily ignited by religious tensions between Catholics and Protestants within the Holy Roman Empire. The immediate cause was the Defenestration of Prague in 1618, where a group of angry Bohemian Protestant activists threw three Catholic officials out of a window at Prague Castle. Surprisingly, the officials were not hurt. But this event became the starting point for the Thirty Years' War, the bloodiest conflict Europe had ever seen.
However, the war was fought over a complex mix of religious, political, and territorial ambitions among Europe's leading powers. As the war progressed, it turned into a broader struggle involving major European powers vying for dominance and control over territories.
While the Thirty Years' War had religious origins, with the conflict between Catholics and Protestants, Richelieu's decision to involve France was not motivated solely by religious considerations. As a Catholic cardinal, Richelieu recognized the political importance of supporting Protestant states to achieve his broader geopolitical goals of weakening the Habsburgs and maintaining the balance of power in Europe.
The Four Phases of the Thirty Years' War:
To better understand the dynamics and flow of this monumental conflict, it is helpful to analyze the war through the lens of its four distinct phases. Each phase was characterized by unique challenges, key players, and significant events that ultimately shaped the events and outcome of the Thirty Years' War as a whole.
By exploring these four phases in detail, we can gain a deeper appreciation for the underlying causes, strategic maneuvers, and far-reaching consequences that made the Thirty Years' War such a pivotal moment in European history.
The Bohemian Phase (1618-1620) and European Involvement:
This initial phase began with the Defenestration of Prague and saw the Protestant Bohemian Estates (modern-day Czech Republic) rebel against the Catholic Habsburg emperor. The Bohemian Revolt was sparked by the Habsburgs' attempts to impose religious uniformity within the Holy Roman Empire, leading to the expulsion of three Catholic officials from a Prague castle window. This symbolic act of defiance marked the start of a broader conflict between the Protestant Bohemian Estates and the Catholic Imperial forces.
The Bohemian Revolt was quickly suppressed by the Habsburgs, who regained control of Bohemia. The Battle of White Mountain (1620) marked a turning point in the Thirty Years' War, leading to the defeat of the Bohemian Revolt and significant consequences for Bohemia. The Imperial Army, led by the Count of Tilly, crushed the Bohemian forces near Prague, resulting in the collapse of the revolt and the flight of King Frederick.
Subsequent punishments included fines, property confiscation, and the execution of 27 revolt leaders, commemorated today by crosses in Prague’s Old Town Square. The suppression of Protestantism destabilized Bohemia’s economy and solidified Habsburg control for the next 300 years. However, this early phase of the war laid the foundation for the broader religious and political tensions that would overwhelm Europe over the next three decades. The Catholic Habsburgs' efforts to confirm their authority over Protestant territories set the stage for continual waves of intervention by other major European powers.

The Spanish were the dominant power in the Catholic side of the conflict, which was fighting against the Protestant Bohemians and their supporters. The Dutch, who had recently declared independence (July 26th, 1581) from the Spanish, were Protestant and had their own reasons for opposing the Spanish. So when the Spanish got involved in supporting the Catholic side, it naturally drew the Dutch into the conflict as well, since they saw the Spanish involvement as a threat to their own interests and independence. The Dutch likely wanted to counterbalance the growing power of the Spanish by supporting the Bohemians and other Protestant forces.
While all this was happening, some other countries that weren't directly involved in the main conflict saw it as a chance to get involved themselves. Specifically, the Ottoman Empire and the region of Savoy (now primarily located in modern-day France and Italy) both decided to join in.
During the Thirty Years' War, Sultan Ahmed I of the Ottoman Empire supported Gabriel Bethlen, Calvinist Prince of Transylvania (now Romania), in his conflict with Holy Roman Emperor Ferdinand II to expand Ottoman influence. Bethlen, with Ottoman backing, was able to take control of northern Hungary and even briefly declare himself King of Hungary in 1620. However, after the Bohemians were defeated by Ferdinand at the Battle of White Mountain, Bethlen made peace with the Holy Roman Emperor. The Ottomans then became heavily involved in their own wars against Poland and Persia, reducing their direct involvement in the Thirty Years' War.
During the Thirty Years' War, Savoy initially supported the Protestant forces against the Habsburgs, providing funds and troops. However, after the Imperial army's victory at the Battle of Sablat (10 June 1619) and the discovery of Savoy's involvement through captured documents, Savoy was forced to withdraw from the conflict.

Danish Intervention in the Thirty Years' War (1625–1629):
The second phase of the Thirty Years' War saw the conflict expand from a primarily German affair into an international war. During the Thirty Years' War, Denmark intervened in 1625 to support Protestant interests against the Holy Roman Emperor Ferdinand II. King Christian IV of Denmark, concerned about the spread of Catholic influence and encouraged by promises of support from England and the Dutch, led this intervention.
Denmark, a powerful Protestant nation controlling vital Baltic trade routes, had close ties to Germany. Christian IV, who was also the Duke of Holstein, sought to expand his influence in northern Germany. However, his attempts to lead a coalition of Protestant states against the Emperor faced significant challenges.
Christian's campaign plan fell apart quickly. His allies, including Count Mansfeld and Christian of Brunswick, suffered defeats, and Christian himself was defeated at the Battle of Lutter in August 1626. Despite efforts to recruit more troops, including Scottish mercenaries, Christian's forces could not stop the advance of the Imperial commander Albrecht von Wallenstein.
By the end of 1627, Wallenstein had occupied significant territories including Mecklenburg, Pomerania, and Jutland. He even planned to build a fleet to challenge Danish control of the Baltic. This prompted Sweden to intervene by sending troops to Stralsund, leading to a failed siege by Wallenstein's deputy.
In 1629, with both sides exhausted and facing additional conflicts, they negotiated the Treaty of Lübeck. Christian IV had to agree to abandon his support for the Protestant German states. In exchange, he was allowed to retain control over Denmark, including the duchies of Schleswig and Holstein. This treaty ended Denmark's status as a leading Nordic power.
The Treaty of Lübeck, signed on May 22, 1629, ended Denmark's involvement in the Thirty Years' War. King Christian IV of Denmark and Norway agreed to abandon support for Protestant German states and cease interference in imperial affairs in exchange for retaining his pre-war territories, including Schleswig and Holstein. The treaty resulted in Denmark-Norway's decline from being a major European power to becoming a politically insignificant state and paved the way for Sweden's rise in the region.
The passage highlights how this phase of the conflict transformed it from a primarily German civil war into a broader international struggle, with the entry of Denmark and the increased involvement of other European powers on both sides of the religious and political divide.
The Swedish Intervention in the Thirty Years' War (1630-1635):
Following the defeat of the Danish intervention, the focus of the Thirty Years' War shifted to the Swedish invasion lasting from 1630 to 1635. King Gustav II Adolf of Sweden ordered an invasion of Catholic states in the Holy Roman Empire, a major turning point in the Thirty Years' War. Though Gustav was killed, the Swedish army defeated its enemies, establishing Sweden as a new European great power. Notably, the Swedish Empire lasted for a century before being overwhelmed in the Great Northern War.
Under the leadership of Gustav II Adolf of Sweden, the Swedish military underwent significant reforms, becoming a highly trained and equipped force. Gustav II Adolf was confident in Swedish military superiority and led his army into battle, achieving notable victories against larger enemy forces.
Despite lacking combat experience, the Swedish army under King Gustav II Adolf proved superior to the Holy Roman Empire's forces. Through bold, disciplined offensives, the Swedes defeated the entrenched Imperial troops at battles like Breitenfeld and Lützen.
The intervention led to significant losses for the Holy Roman Empire, including the defeat of over 100,000 Imperial troops. Overall, the Swedish Intervention in the Thirty Years' War demonstrated the effectiveness of offensive military tactics and established Sweden as a major player in European politics.
Even after the death of King Gustav II Adolf at the Battle of Lützen, the Swedish army continued its successful advance into Catholic territories, until the Peace of Westphalia was signed in 1648. Sweden's rise as a European great power was confirmed and gained control of the Baltic, as the Holy Roman Empire's power began declining due to Sweden's pivotal role in the Thirty Years' War.
French intervention (1635 to 1648):
As the Thirty Years' War progressed, France, a rival of the Holy Roman Empire, decided to intervene directly in the conflict. Fearing the growing power of the Habsburgs, France signed a treaty with Sweden in 1631 to provide financial support in exchange for Sweden maintaining an army against the Habsburgs.
After the Swedish defeat at Nördlingen in 1634, France declared war on Spain in May 1635, and on the Holy Roman Empire in August 1636, aligning its strategy with Sweden. Despite early French military setbacks, the tide eventually turned, with victories like the capture of Arras from the Spanish in 1640 and the decisive French win at Rocroi in 1643.
Historians mark the Battle of Rocroi in 1643 as a decisive turning point. The French victory, with 4,000 casualties compared to the Spanish losses of 7,000 dead and wounded, plus 8,000 captured, marked the first defeat of the Spanish Tercios in nearly a century. Supported by the French, revolts by the Catalonians, Neapolitans, and Portuguese further weakened Spanish control. This battle is often considered the end of Spanish dominance in Europe. Notably it was also the beginning of French hegemony in the region.
The French triumph shattered the Tercios' long-standing dominance and bolstered France's prestige. It cemented France's status as the preeminent power in Western Europe during the Thirty Years' War. The Battle of Rocroi allowed France to assert its influence, setting the stage for its continued ascendency in the decades and centuries to come.
In 1646, French and Swedish forces invaded Bavaria, prompting Maximilian (Elector of Bavaria, A Devout Catholic German Price of the Holy Roman Emperor) to seek peace. Despite continued battles and internal strife, such as the Swedish siege of Prague in 1648, the war ended with peace treaties signed in October 1648. These treaties concluded the Thirty Years' War, reshaping European politics and diminishing the power of the Holy Roman Empire.
The Peace of Westphalia and French Triumph:
The Thirty Years' War was driven by differences over religion and Imperial authority, but in a broader context, it was driven by the competition for power and influence in Europe between the Habsburg-ruled Spain and Austria controlled by the Germanic Tribes on one side, and the French House of Bourbon and Swedish Empire on the other. Notably, Russia and England were not major powers in European affairs at the time, as the Tsardom of Russia was still consolidating its power and territorial control, and the unified Kingdom of England did not yet exist, emerging later in 1707 through the Acts of Union.
The Thirty Years' War did not have a clear-cut winner. Instead, the war concluded with the Peace of Westphalia in 1648, which established a new balance of power in Europe. While no single entity emerged as the outright victor, France and Sweden gained significant territorial and political advantages. The Holy Roman Empire and the Habsburgs, despite retaining their positions, saw their influence considerably weakened.
The Peace of Westphalia was a series of peace treaties signed in 1648 that brought an end to the Thirty Years' War in Europe. Negotiated in the Westphalian towns of Münster and Osnabrück, the treaties not only concluded the German phase of the Thirty Years' War, but also resolved the Eighty Years' War (1568-1648) between Spain and the Dutch Republic.
The Peace of Westphalia marked a significant turning point in European history, as it established a new political order and balance of power on the continent. Key outcomes included the recognition of the sovereignty and independence of the Dutch Republic, as well as the decentralization of the Holy Roman Empire, which granted greater autonomy to its constituent territories. It made some key territorial adjustments, such as recognizing Switzerland's independence from the Holy Roman Empire. It also abolished barriers to trade and commerce, and established some degree of free navigation on the Rhine River.

While no single entity emerged as the outright victor from the conflict, one nation stood to gain the most - France. The treaties signed at Westphalia paved the way for France to assert itself as a preeminent force on the continent. Several key outcomes of the Peace of Westphalia contributed to France's newfound influence. Firstly, the treaties weakened the power of the Holy Roman Empire and the Catholic Habsburgs, who had been the dominant political and military force in central Europe. This power vacuum allowed France to expand its territorial holdings and political sway.

Additionally, the Peace of Westphalia affirmed the principle of state sovereignty, empowering secular rulers and diminishing the authority of the Holy Roman Emperor and the Catholic Church. This shift aligned with France's own centralized, absolutist model of governance under Louis XIV. With its neighbors effectively neutralized, France was able to capitalize on the new geopolitical order and cement its status as the leading power in Europe.
Furthermore, the treaties granted significant concessions to France, including the annexation of the strategically important Alsace region. This not only enhanced France's territorial control, but also provided a springboard for further expansion and influence throughout the continent. The French also gained a voice in the governance of the Holy Roman Empire, giving them a direct role in shaping the political landscape.
In the decades following the Peace of Westphalia, France's power and prestige continued to grow. Under the long reign of Louis XIV, often referred to as the "Sun King," France became the cultural, economic, and military epicenter of Europe. The Thirty Years' War and its aftermath had firmly established France as the preeminent force to be reckoned with on the European stage.
The Peace of Westphalia redefined the balance of power, establishing state sovereignty principles that influence international relations today. France emerged as the principal beneficiary, gaining territory and influence, which propelled it to preeminence in European affairs. The war's impact on the German lands highlighted the profound human cost of this protracted conflict.
Consequences of the Thirty Years' War:
The Peace of Westphalia redefined European power balance, establishing state sovereignty principles that influence international relations today. France emerged as the main beneficiary, gaining territory and influence, becoming a leading European power. The war caused over 8 million casualties from combat, famine, and disease.
The Thirty Years' War significantly impacted Europe's power structure. The Holy Roman Empire's influence waned, and France's strength grew. The Peace of Westphalia recognized France as a major power and decentralized the Holy Roman Empire, transforming it into a loose confederation, paving the way for its eventual dissolution in the early 19th century.
The war resulted in major political and territorial changes. Sovereignty and independence of various territories weakened the Holy Roman Empire's central authority, allowing powerful nation-states like France to rise. The shift in power dynamics led to the decline of the Habsburgs and the rise of France as the leading European power. The war's human cost was severe, with millions of casualties and widespread devastation across the German lands.
Conclusion:
Ultimately, the Thirty Years' War, which began with an anti-Habsburg revolt in Bohemia in 1618, turned into a complex conflict involving the Holy Roman Empire, religion, and the broader European state system. While originally a "German war," foreign powers such as Sweden and France became heavily involved.
The Peace of Westphalia, concluded in 1648 in the German city of Münster, finally brought an end to the Thirty Years' War. This peace settlement consisted of two treaties signed between the Holy Roman Empire and the new major European powers of Sweden and France.
The Peace of Westphalia effectively settled the internal conflicts within the Holy Roman Empire, with Sweden and France serving as guarantors of the agreement. This landmark treaty reshaped the political landscape of Europe, granting more autonomy to the individual states within the empire and shifting the balance of power on the continent. Eventually, the Thirty Years' War underscored the complex interplay between religion, politics, and power, climaxing in the ascendency of France.
In the end, the Franco-German enmity, which began with the Thirty Years' War, was a significant factor in later conflicts such as the Fall of Berlin in 1806, the Franco-Prussian War of 1870–1871, the unification of Germany (excluding Austria), and World War I. This hostility ended after World War II, when, under the influence of the Cold War, West Germany and France both became part of NATO and the European Coal and Steel Community.
