Ferdinand II vs George IV

Ferdinand II was elected Holy Roman Emperor in Frankfurt, succeeding his cousin Matthias. His election was contested by the Protestant Union, which supported Frederick V of the Palatinate. Ferdinand's staunch Catholicism and determination to suppress Protestantism set the stage for the Thirty Years' War.

Ferdinand II's Catholic forces, led by General Tilly, decisively defeated the Protestant Bohemian army at the Battle of White Mountain near Prague. This victory crushed the Bohemian Revolt and allowed Ferdinand to reassert Catholic control over Bohemia. The battle was a key early event in the Thirty Years' War.

Ferdinand II issued the Edict of Restitution, which ordered the return of all church lands seized by Protestants since the Peace of Augsburg (1555). This aggressive Catholic policy alienated many Protestant princes and led to the intervention of Sweden in the Thirty Years' War. The edict was a major cause of the war's escalation.

Ferdinand II's imperial forces, under General Tilly, besieged and sacked the Protestant city of Magdeburg. The city was destroyed, and an estimated 20,000 inhabitants were killed in the massacre. The sack of Magdeburg became a symbol of the brutality of the Thirty Years' War and galvanized Protestant resistance.

Ferdinand II signed the Peace of Prague with the Protestant Elector John George I of Saxony, ending the war between the Emperor and many German Protestant states. The treaty modified the Edict of Restitution and granted amnesty to most Protestant princes. However, it did not end the broader Thirty Years' War, as Sweden and France continued fighting.

George IV became Prince Regent after his father George III was declared mentally unfit. He ruled as regent for nine years, overseeing the final years of the Napoleonic Wars and the Congress of Vienna. The Regency era was marked by cultural and architectural developments.

George IV became king upon the death of his father George III. His accession was overshadowed by his attempt to divorce his wife Caroline of Brunswick, leading to a public scandal. He was crowned in a lavish ceremony at Westminster Abbey.

George IV reluctantly gave royal assent to the Catholic Relief Act, which removed most restrictions on Catholics in the United Kingdom. This act allowed Catholics to sit in Parliament and hold public office. It was a major step toward religious equality.

George IV died of gastrointestinal illness at Windsor Castle at age 67. He was buried in St George's Chapel. His death ended the Regency era and passed the throne to his brother William IV. His reign was marked by extravagance and scandal.
