Treaty of Münster (October 1648) in the context of "Ferdinand III, Holy Roman Emperor"

The Peace of Westphalia (German: Westfälischer Friede, pronounced [vɛstˈfɛːlɪʃɐ ˈfʁiːdə] ) is the collective name for two peace treaties signed in October 1648 in the Westphalian cities of Osnabrück and Münster. They ended the Thirty Years' War (1618–1648) and brought peace to the Holy Roman Empire, closing a calamitous period of European history that killed approximately eight million people. Ferdinand III, Holy Roman Emperor, the kingdoms of France and Sweden, and their respective allies among the princes of the Holy Roman Empire, participated in the treaties.

The negotiation process was lengthy and complex. Talks took place in two cities, because each side wanted to meet on territory under its own control. A total of 109 delegations arrived to represent the belligerent states, but not all delegations were present at the same time. Two treaties were signed to end the war in the Empire: the Treaty of Münster and the Treaty of Osnabrück. These treaties ended the Thirty Years' War in the Holy Roman Empire, with the Habsburgs (rulers of Austria and Spain) and their Catholic allies on one side, battling the Protestant powers (Sweden and certain Holy Roman principalities) allied with France (though Catholic, strongly anti-Habsburg under King Louis XIV).

The Austrian Netherlands was the territory of the Burgundian Circle of the Holy Roman Empire between 1714 and 1797. The period began with the acquisition by the Austrian Habsburg monarchy of the former Spanish Netherlands under the Treaty of Rastatt in 1714. It lasted until Revolutionary France annexed the territory after the Battle of Sprimont in 1794 and the Peace of Basel in 1795. Austria relinquished its claim on the province in 1797 through the Treaty of Campo Formio.

The Netherlands, previously the Burgundian Netherlands, inherited by the Spanish branch of the Habsburgs, having revolted against the absolutism and centralism of Philip II of Spain, their common sovereign, launched a war which led in fact, in 1568, to the formation in the north of the Republic of the United Provinces, a new state whose independence would finally be recognized by the King of Spain in 1648 during the Treaty of Münster, and in the south of a group of around ten provinces which Philip II and then his successors managed to preserve under the name of Spanish Netherlands.
