French–Habsburg rivalry in the context of "Thirty Years War"

The Ottoman–Habsburg wars were fought from the 16th to the 18th centuries between the Ottoman Empire and the Habsburg monarchy, which was at times supported by the Kingdom of Hungary, Polish–Lithuanian Commonwealth, The Holy Roman Empire, and Habsburg Spain. The wars were dominated by land campaigns in Hungary, including Transylvania (today in Romania) and Vojvodina (today in Serbia), Croatia, and central Serbia.

By the 16th century, the Ottomans had become a serious threat to European powers, with Ottoman ships sweeping away Venetian possessions in the Aegean and Ionian seas and Ottoman-supported Barbary pirates seizing Spanish possessions in the Maghreb. The Protestant Reformation, French–Habsburg rivalry and the numerous civil conflicts of the Holy Roman Empire distracted Christians from their conflict with the Ottomans. Meanwhile, the Ottomans had to contend with Safavid Empire and also to a lesser extent the Mamluk Sultanate, which was defeated by the Ottomans under Selim I rule and later fully incorporated into the empire.

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 Seven Years' War, 1756 to 1763, was a global war fought by numerous great powers, primarily in Europe, with significant subsidiary campaigns in North America and South Asia. The warring states were Great Britain and Prussia fighting against France and Austria, with other countries joining these coalitions: Portugal, Spain, Saxony, Sweden, and Russia. Related conflicts include the Third Silesian War, French and Indian War, Third Carnatic War, Anglo-Spanish War (1762–1763), and Spanish–Portuguese War.

Although the War of the Austrian Succession ended with the Treaty of Aix-la-Chapelle (1748), none of the signatories were happy with the terms, and it was generally viewed as a temporary armistice. It led to a strategic realignment known as the Diplomatic Revolution that ended the long-running rivalry between Austria and France. The two declared war on Britain after signing the Treaty of Versailles (1756), with a second agreement in 1757 bringing Prussia into the war.

The Dutch States Navy (Dutch: Staatse vloot, lit. 'States fleet') was the navy of the Dutch Republic from 1588 to 1795. Coming into existence during the Eighty Years' War, the States Navy played a major role in expanding and protecting the Dutch colonial empire, in addition to participating in numerous conflicts with rival European powers. The States Navy consisted of five admiralties, which were respectively based in Amsterdam, Friesland, the Noorderkwartier, Rotterdam and Zeeland. This organisational structure contributed to the decentralised nature of the States Navy, which heavily relied upon privateers and armed merchantmen in times of war.

In addition to the Eighty Years' War, the States Navy also participated in the Anglo-Dutch Wars, the Dutch–Portuguese War, the Northern Wars, the Franco-Dutch War and various conflicts of the French–Habsburg rivalry. It also played a major role in protecting Dutch overseas trade, including Dutch involvement in the triangular trade and the Atlantic slave trade. As a result of the War of the First Coalition, the Dutch Republic ceased to exist in 1795, being succeeded by the Batavian Republic; the States Navy was correspondingly transformed into the Batavian Navy. The current navy of the Netherlands, the Royal Netherlands Navy, is the modern successor of the States Navy and inherited many of its traditions.

The Italian Wars were a series of conflicts fought between 1494 and 1559 in the Italian Peninsula, with subsidiary theatres in Flanders, the Rhineland and Mediterranean Sea. A product of the long-running French–Habsburg rivalry, its primary belligerents were France versus the Holy Roman Empire and Spain, supported by numerous Italian states at different stages, along with England, and the Ottoman Empire.

The collapse of the Italic League in 1492 allowed Charles VIII of France to invade Naples in 1494, which drew in Spain and the Holy Roman Empire. Although he was forced to withdraw in 1495, ongoing political divisions among the Italian states made them a battleground in the struggle for European domination between France and the Habsburgs.
