The Protestant Union (German : Protestantische Union), also known as the Evangelical Union, Union of Auhausen, German Union or the Protestant Action Party, was a coalition of Protestant German states. It was formed on 14 May 1608 by Frederick IV, Elector Palatine in order to defend the rights, land and safety of each member. It included both Calvinist and Lutheran states, and dissolved in 1621.
The union was formed following two events. Firstly, the Holy Roman Emperor Rudolf II and Bavarian Duke Maximilian I reestablished Catholicism in Donauwörth in 1607. Secondly, by 1608, a majority of the Imperial Diet had decided that the renewal of the 1555 Peace of Augsburg should be conditional upon the restoration of all church land appropriated since 1552. The Protestant princes met in Auhausen, and formed a coalition of Protestant states under the leadership of Frederick IV on 14 May 1608. In response, the Catholic League organized the following year, headed by Duke Maximilian. [1]
Members of the Protestant Union included the Palatinate, Neuburg, Württemberg, Baden-Durlach, Ansbach, Bayreuth, Anhalt, Zweibrücken, Oettingen, Hesse-Kassel, Brandenburg, and the free cities of Ulm, Strasbourg, Nuremberg, Rothenburg, Windsheim, Schweinfurt, Weissenburg, Nördlingen, Schwäbisch Hall, Heilbronn, Memmingen, Kempten, Landau, Worms, Speyer, Aalen and Giengen. [2]
However, the Protestant Union was weakened from the start by the non-participation of several powerful German Protestant rulers, notably the Elector of Saxony. The Union was also beset by internal strife between its Lutheran and Calvinist members. [3]
In 1619, Frederick V of the Palatinate accepted the crown of Bohemia in opposition to Holy Roman Emperor Ferdinand II. On 3 July 1620 the Protestant Union signed the Treaty of Ulm (German : Ulmer Vertrag), declaring neutrality and declining to support Frederick V. [4] In January 1621, Ferdinand II imposed an imperial ban upon Frederick V and moved his right to elect an emperor to Maximilian. Electoral Palatinate also lost the Upper Palatinate to Bavaria. The Protestant Union met in Heilbronn in February and formally protested Ferdinand's actions. He ignored this complaint and ordered the Protestant Union to disband its army. The members of the union complied with Ferdinand's demand under the Mainz accord in May, and on 14 May 1621 it was formally dissolved. [5]
A new separate union without connection to this one emerged twelve years later, the Heilbronn League. It allied some Protestant states in western, central and southern Germany, and fought against the Holy Roman Emperor under the guidance of Sweden and France, which were at the same time parties to that league.
Intending to strengthen the security provided by the Peace of Augsburg, Protestants formed the union in 1608. Its leaders created guidelines and agreements to live by as follows:
In 1555, the Peace of Augsburg was signed by Charles V and Lutheran princes. This treaty gave Roman Catholic and Lutheran princes the freedom to decide the religion which their respective state would be under, but gave no such protection to Calvinist princes. In 1608, Protestant princes formed the alliance known as Protestant Union. The next year, the Catholic League was created. In 1610, the Union intervened in the War of the Jülich Succession. [7] In 1618, the Thirty Years' War began with the outbreak of the Bohemian Revolt. Frederick V, Elector Palatine, accepted the crown of Bohemia the following year. The Union declared its neutrality in the conflict between Frederick and the Catholic League in the 1620 Treaty of Ulm. The Union dissolved the next year.
George William, of the Hohenzollern dynasty, was Margrave and Elector of Brandenburg and Duke of Prussia from 1619 until his death. His reign was marked by ineffective governance during the Thirty Years' War. He was the father of Frederick William, the "Great Elector".
The Peace of Westphalia 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. Holy Roman Emperor Ferdinand III, the kingdoms of France and Sweden, and their respective allies among the princes of the Holy Roman Empire, participated in the treaties.
The Thirty Years' War was one of the longest and most destructive conflicts in European history, lasting from 1618 to 1648. Fought primarily in Central Europe, an estimated 4.5 to 8 million soldiers and civilians died as a result of battle, famine, or disease, while parts of present-day Germany reported 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.
The Battle of White Mountain was an important battle in the early stages of the Thirty Years' War. It led to the defeat of the Bohemian Revolt and ensured Habsburg control for the next three hundred years.
Frederick V was the Elector Palatine of the Rhine in the Holy Roman Empire from 1610 to 1623, and reigned as King of Bohemia from 1619 to 1620. He was forced to abdicate both roles, and the brevity of his reign in Bohemia earned him the derisive sobriquet "the Winter King".
The Schmalkaldic League was a military alliance of Lutheran princes within the Holy Roman Empire during the mid-16th century. It received its name from the town of Schmalkalden, which is located in modern Thuringia.
The Battle of Wimpfen took place during the Palatinate campaign period of the Thirty Years' War on 6 May 1622 near Wimpfen.
The Catholic League was a coalition of Catholic states of the Holy Roman Empire formed 10 July 1609. While initially formed as a confederation to act politically to negotiate issues vis-à-vis the Protestant Union, modelled on the more intransigent ultra-Catholic French Catholic League (1576), it was subsequently concluded as a military alliance "for the defence of the Catholic religion and peace within the Empire".
Cuius regio, eius religio is a Latin phrase which literally means "whose realm, their religion" – meaning that the religion of the ruler was to dictate the religion of those ruled. This legal principle marked a major development in the collective freedom of religion within Western civilization. Before tolerance of individual religious divergences became accepted, most statesmen and political theorists took it for granted that religious diversity weakened a state – and particularly weakened ecclesiastically-transmitted control and monitoring in a state. The principle of "cuius regio" was a compromise in the conflict between this paradigm of statecraft and the emerging trend toward religious pluralism developing throughout the German-speaking lands of the Holy Roman Empire. It permitted assortative migration of adherents to two religious groups, Roman Catholic and Lutheran, eliding other confessions.
Philip I, Landgrave of Hesse, nicknamed der Großmütige, was a German nobleman and champion of the Protestant Reformation, notable for being one of the most important of the early Protestant rulers in Germany. He was one of the main belligerents in the War of the Katzenelnbogen Succession.
The Peace of Prague, dated 30 May 1635 Old Style, was a significant turning point in the Thirty Years' War. Signed by John George I, Elector of Saxony, and Ferdinand II, Holy Roman Emperor, the terms ended Saxony's support for the anti-Imperial coalition led by Sweden.
The Heilbronn League was formed in the Free Imperial City of Heilbronn, on 23 April 1633, during the Thirty Years' War. Led by Sweden, it brought together various Protestant states in western and northern Germany. It was supported by Saxony and Brandenburg-Prussia, although they were not members.
Christian I, Prince of Anhalt-Bernburg, also known as Christian of Anhalt, was a German prince of the House of Ascania. He was ruling prince of Anhalt and, from 1603, ruling prince of the revived principality of Anhalt-Bernburg. From 1595 he was governor of Upper Palatinate, and soon became the advisor-in-chief of Frederick IV, Elector Palatine.
The Treaty of Fontainebleau was signed on 30 May 1631 during the Thirty Years' War, at the Palace of Fontainebleau. It was a pact of mutual assistance between Maximilian I, Elector of Bavaria, and France, for a period of eight years.
The Bohemian Revolt was an uprising of the Bohemian estates against the rule of the Habsburg dynasty that began the Thirty Years' War. It was caused by both religious and power disputes. The estates were almost entirely Protestant, mostly Utraquist Hussite but there was also a substantial German population that endorsed Lutheranism. The dispute culminated after several battles in the final Battle of White Mountain, where the estates suffered a decisive defeat. This started re-Catholisation of the Czech lands, but also expanded the scope of the Thirty Years' War by drawing Denmark and Sweden into it. The conflict spread to the rest of Europe and devastated vast areas of Central Europe, including the Czech lands, which were particularly stricken by its violent atrocities.
The Palatinate campaign, also known as the Spanish conquest of the Palatinate or the Palatinate phase of the Thirty Years' War was a campaign conducted by the Imperial army of the Holy Roman Empire against the Protestant Union in the Lower Palatinate, during the Thirty Years' War.
