Reformation_The Reformation The Reformation (alternatively named the Protestant Reformation, and the European Reformation) was a major movement in Western Christianity in 16th-century Europe that posed a religious and political challenge to the Catholic Church and in part, it also posed a challenge to papal authority. The Reformation marked the start of Protestantism and in the Western Church, the Latin Church, remained the Catholic Church. It is considered one of the events that signified the end of the Middle Ages and the beginning of the early modern period in Europe.
Congress of ViennaThe Congress of Vienna of 1814–1815 was a series of international diplomatic meetings to discuss and agree upon a possible new layout of the European political and constitutional order after the downfall of the French Emperor Napoleon Bonaparte. Participants were representatives of all European powers and other stakeholders, chaired by Austrian statesman Klemens von Metternich, and held in Vienna from September 1814 to June 1815.
