Thirty Years' War
The Thirty Years' War, fought primarily in Central Europe between 1618 and 1648, was one of the most destructive conflicts in human history. An estimated 4.5 to 8 million soldiers and civilians died from the effects of battle, famine, or disease, with parts of Germany reporting population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War, the Torstenson War, the Dutch–Portuguese War, and the Portuguese Restoration War.
Its causes derived from religious conflict within the Holy Roman Empire, sparked by the 16th-century Reformation. The 1555 Peace of Augsburg attempted to resolve this by dividing the Empire into Catholic and Lutheran states, but was later destabilised by the expansion of Protestantism beyond these boundaries. Combined with disagreements over the limits of imperial authority, religion was thus an important factor in starting the war. However, its scope and extent was largely the consequence of external drivers such as the French–Habsburg rivalry and the Dutch Revolt.
The war began in 1618, when the Catholic Emperor Ferdinand II was replaced as king of Bohemia by the Protestant Frederick V of the Palatinate. Although Ferdinand quickly regained control of Bohemia, Frederick's participation expanded fighting into the Palatinate, whose strategic importance drew in the Dutch Republic and Spain, then engaged in the Eighty Years' War. In addition, the acquisition of territories within the Empire by rulers like Christian IV of Denmark and Gustavus Adolphus of Sweden gave them and other foreign powers an ongoing motive to intervene. Combined with fears that the Protestant religion in general was threatened, these factors turned an internal dynastic dispute into a European conflict.
The period 1618 to 1635 was primarily a civil war within the Holy Roman Empire, which largely ended with the Peace of Prague. However, France's entry into the war in alliance with Sweden turned the empire into one theatre of a wider struggle with their Habsburg rivals, Emperor Ferdinand III and Spain. Fighting ended with the 1648 Peace of Westphalia, whose terms included greater autonomy for states like Bavaria and Saxony, as well as acceptance of Dutch independence by Spain. The conflict shifted the balance of power in favour of France and its subsequent expansion under Louis XIV.
The 16th century Reformation caused open warfare between Protestants and Catholics within the Holy Roman Empire, which ended with the 1552 Peace of Passau. The Peace of Augsburg in 1555 tried to prevent a recurrence by fixing boundaries between the two faiths, using the principle of cuius regio, eius religio. States were designated as either Lutheran, then the most usual form of Protestantism, or Catholic, based on the religion of their ruler. Other provisions protected substantial religious minorities in cities like Donauwörth, and confirmed Lutheran ownership of property taken from the Catholic Church since 1552.
However, the settlement was undermined by the expansion of Protestantism into Catholic areas post-1555, particularly Calvinism, a Protestant doctrine viewed with hostility by both Lutherans and Catholics. Augsburg also gave individual rulers significantly greater autonomy, allowing larger states to pursue their own objectives, which often clashed with those of central authority or external powers. Conflict sometimes superseded religion, with the Protestant states of Saxony and Brandenburg competing with Denmark–Norway and Sweden over the lucrative Baltic trade.
Reconciling these differences was hampered by fragmented political institutions, which included 300 imperial estates distributed across Germany, the Low Countries, northern Italy, and present-day France. These ranged in size and importance from the seven Prince-electors who voted for the Holy Roman Emperor, down to Prince-bishoprics and imperial cities like Hamburg. Each also belonged to a separate regional grouping known as an Imperial Circle, which was chiefly concerned with defence, and operated independently. Above all of these was the Imperial Diet, which assembled infrequently, and focused on discussion, rather than legislation.
Since 1440, the position of emperor had been held by the House of Habsburg, the largest single landowner within the Holy Roman Empire. They directly ruled over eight million subjects and territories that included Austria, Bohemia and Hungary. The Habsburgs also controlled the Spanish Empire until 1556, when Charles V divided his possessions between different branches of the family. This bond was reinforced by frequent inter-marriage, while Spain retained territories within the Holy Roman Empire such as the Spanish Netherlands, Milan and Franche-Comté. However, although the two often collaborated, there was no such thing as a joint "Habsburg" policy.
