War of the Spanish Succession: Battle of Blenheim: English and Imperial forces are victorious over French and Bavarian troops.

The War of the Spanish Succession was a European great power conflict, fought between 1701 to 1714. The death of Charles II of Spain in November 1700 without children resulted in a struggle for the Spanish Empire between rival claimants. Charles named his heir as Philip of Anjou, who was backed by his grandfather Louis XIV of France. His opponent, Archduke Charles of Austria, was supported by the Grand Alliance. Significant related conflicts include the Great Northern War (1700–1721) and Queen Anne's War (1702–1713).

The Battle of Blenheim fought on 13 August [O.S. 2 August] 1704, was a major battle of the War of the Spanish Succession. The overwhelming Allied victory ensured the safety of Vienna from the Franco-Bavarian army, thus preventing the collapse of the reconstituted Grand Alliance.

The Kingdom of England was a sovereign state on the island of Great Britain from the 10th century, when it was unified from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern periods.

The Holy Roman Empire, also known as the Holy Roman Empire of the German Nation after 1512, was a polity in Central and Western Europe, usually headed by the Holy Roman Emperor. It developed in the Early Middle Ages, and lasted for a millennium until its dissolution in 1806 during the Napoleonic Wars. For most of its history the Empire comprised the entirety of the modern countries of Germany, Czechia, Austria, the Netherlands, Switzerland, Slovenia, and Luxembourg, most of north-central Italy and southern Belgium, and large parts of modern-day east France and west Poland.
