context_page_description: Protestantism is the second-largest form of Christianity with a total of 800 million to 1 billion adherents worldwide or about 37% of all Christians. It originated with the 16th century Reformation, a movement against what its followers perceived to be errors in the Catholic Church. Protestants reject the Roman Catholic doctrine of papal supremacy and sacraments, but disagree among themselves regarding the real presence of Christ in the Eucharist and matters of church polity and apostolic succession. They emphasize the priesthood of all believers, justification by faith alone rather than also by good works, and the highest authority of the Bible alone in faith and morals. The "five solae" summarise basic theological differences in opposition to the Catholic Church.
  Protestantism began in Germany in 1517, when Martin Luther published his Ninety-five Theses as a reaction against abuses in the sale of indulgences by the Catholic Church, which purported to offer the remission of the temporal punishment of sins to their purchasers.
context_section_description: The Protestant Reformation began as an attempt to reform the Catholic Church.
  On 31 October 1517 (All Hallows' Eve) Martin Luther allegedly nailed his Ninety-five Theses (Disputation on the Power of Indulgences) on the door of the All Saints' Church in Wittenberg, Germany, detailing doctrinal and practical abuses of the Catholic Church, especially the selling of indulgences. The theses debated and criticized many aspects of the Church and the papacy, including the practice of purgatory, particular judgment, and the authority of the pope. Luther would later write works against the Catholic devotion to Virgin Mary, the intercession of and devotion to the saints, mandatory clerical celibacy, monasticism, the authority of the pope, the ecclesiastical law, censure and excommunication, the role of secular rulers in religious matters, the relationship between Christianity and the law, good works, and the sacraments.
  The Reformation was a triumph of literacy and the new printing press invented by Johannes Gutenberg.  Luther's translation of the Bible into German was a decisive moment in the spread of literacy, and stimulated as well the printing and distribution of religious books and pamphlets. From 1517 onward, religious pamphlets flooded much of Europe.
  Following the excommunication of Luther and condemnation of the Reformation by the Pope, the work and writings of John Calvin were influential in establishing a loose consensus among various groups in Switzerland, Scotland, Hungary, Germany and elsewhere. After the expulsion of its Bishop in 1526, and the unsuccessful attempts of the Bern reformer William Farel, Calvin was asked to use the organisational skill he had gathered as a student of law to discipline the city of Geneva. His Ordinances of 1541 involved a collaboration of Church affairs with the City council and consistory to bring morality to all areas of life. After the establishment of the Geneva academy in 1559, Geneva became the unofficial capital of the Protestant movement, providing refuge for Protestant exiles from all over Europe and educating them as Calvinist missionaries. The faith continued to spread after Calvin's death in 1563.
  Protestantism also spread from the German lands into France, where the Protestants were nicknamed Huguenots. Calvin continued to take an interest in the French religious affairs from his base in Geneva. He regularly trained pastors to lead congregations there. Despite heavy persecution, the Reformed tradition made steady progress across large sections of the nation, appealing to people alienated by the obduracy and the complacency of the Catholic establishment. French Protestantism came to acquire a distinctly political character, made all the more obvious by the conversions of nobles during the 1550s. This established the preconditions for a series of conflicts, known as the French Wars of Religion. The civil wars gained impetus with the sudden death of Henry II of France in 1559. Atrocity and outrage became the defining characteristics of the time, illustrated at their most intense in the St. Bartholomew's Day massacre of August 1572, when the Catholic party annihilated between 30,000 and 100,000 Huguenots across France. The wars only concluded when Henry IV of France issued the Edict of Nantes, promising official toleration of the Protestant minority, but under highly restricted conditions. Catholicism remained the official state religion, and the fortunes of French Protestants gradually declined over the next century, culminating in Louis XIV's Edict of Fontainebleau which revoked the Edict of Nantes and made Catholicism the sole legal religion once again. In response to the Edict of Fontainebleau, Frederick William I, Elector of Brandenburg declared the Edict of Potsdam, giving free passage to Huguenot refugees. In the late 17th century many Huguenots fled to England, the Netherlands, Prussia, Switzerland, and the English and Dutch overseas colonies. A significant community in France remained in the Cévennes region.
  Parallel to events in Germany, a movement began in Switzerlan
