Title: Louis XIV
Content:  Louis was a pious and devout king who saw himself as the head and protector of the Catholic Church in France. He made his devotions daily regardless of where he was, following the liturgical calendar regularly. Under the influence of his very religious second wife, he became much stronger in the practice of his Catholic faith. This included banning opera and comedy performances during Lent. Towards the middle and the end of his reign, the centre for the King's religious observances was usually the Chapelle Royale at Versailles. Ostentation was a distinguishing feature of daily Mass, annual celebrations, such as those of Holy Week, and special ceremonies. Louis established the Paris Foreign Missions Society, but his informal alliance with the Ottoman Empire was criticised for undermining Christendom.
Title: Louis IV, Holy Roman Emperor
Content:   Louis IV (Ludwig; 1 April 1282 – 11 October 1347), called the Bavarian, of the house of Wittelsbach, was King of the Romans from 1314, King of Italy from 1327, and Holy Roman Emperor from 1328. Louis' election as king of Germany in 1314 was controversial, as his Habsburg cousin Frederick the Fair was simultaneously elected king by a separate set of electors. Louis defeated Frederick in the Battle of Mühldorf in 1322, and the two eventually reconciled. Louis was opposed and excommunicated by the French Pope John XXII; Louis in turn attempted to depose the pope and install an anti-pope. Louis IV was Duke of Upper Bavaria from 1294 to 1301 together with his elder brother Rudolf I, was Margrave of Brandenburg until 1323, and Count Palatine of the Rhine until 1329, and became Duke of Lower Bavaria in 1340. He became Count of Hainaut, Holland, Zeeland, and Friesland in 1345 when his wife Margaret inherited those domains.
Title: Louis X of France
Content:  Louis X (4 October 1289 – 5 June 1316), called the Quarrelsome, the Headstrong, or the Stubborn (le Hutin), was King of France from 1314 to 1316 and King of Navarre as Louis I (Luis I a Nafarroakoa), from 1305 until his death in 1316. He abolished slavery, emancipated serfs who could pay their freedom, and readmitted Jews in the kingdom. His short reign in France was marked by tensions with the nobility, due to fiscal and centralization reforms initiated by Enguerrand de Marigny, the Grand Chamberlain of France, under the reign of his father. Louis' uncle—Charles of Valois, leader of the feudalist party—managed to convince the king to execute Enguerrand de Marigny.
Title: Early modern period
Content:  For much of the reign of Louis XIV, who was known as the Sun King (French: le Roi Soleil), France stood as the leading power in Europe, engaging in three major wars—the Franco-Dutch War, the War of the League of Augsburg, and the War of the Spanish Succession—and two minor conflicts—the War of Devolution, and the War of the Reunions. Louis ruled according to the Divine Right of Kings, the theory that the King was crowned by God and accountable to him alone. Consequently, he has long been considered the archetypal absolute monarch. Louis XIV continued the work of his predecessor to create a centralized state, governed from the 
Title: Louis XIV
Content:   Louis decided to persecute Protestants and revoke the 1598 Edict of Nantes, which awarded Huguenots political and religious freedom. He saw the persistence of Protestantism as a disgraceful reminder of royal powerlessness. After all, the Edict was the pragmatic concession of his grandfather Henry IV to end the longstanding French Wars of Religion. An additional factor in Louis' thinking was the prevailing contemporary European principle to assure socio-political stability, cuius regio, eius religio ("whose realm, his religion"), the idea that the religion of the ruler should be the religion of the realm (as originally confirmed in central Europe in the Peace of Augsburg

Content:  end, however, despite renewed tensions with the Camisards of south-central France at the end of his reign, Louis may have helped ensure that his successor would experience fewer instances of the religion-based disturbances that had plagued his forebears. French society would sufficiently change by the time of his descendant, Louis XVI, to welcome tolerance in the form of the 1787 Edict of Versailles, also known as the Edict of Tolerance. This restored to non-Catholics their civil rights and the freedom to worship openly. With the advent of the French Revolution in 1789, Protestants were granted equal rights with their Roman Catholic counterparts.
Title: History of France
Content:  Louis XIV, known as the "Sun King", reigned over France from 1643 until 1715 although his strongest period of personal rule did not begin until 1661 after the death of his Italian chief minister Cardinal Mazarin. Louis believed in the divine right of kings, which asserts that a monarch is above everyone except God, and is therefore not answerable to the will of his people, the aristocracy, or the Church. Louis continued his predecessors' work of creating a centralized state governed from Paris, sought to eliminate remnants of feudalism in France, and subjugated and weakened the aristocracy. By these means he consolidated a system of absolute

An adherent of the concept of the divine right of kings, Louis continued his predecessors' work of creating a centralised state governed from the capital. He sought to eliminate the remnants of feudalism persisting in parts of France and, by compelling many members of the nobility to inhabit his lavish Palace of Versailles, succeeded in pacifying the aristocracy, many members of which had participated in the Fronde rebellion during his minority. By these means he became one of the most powerful French monarchs and consolidated a system of absolute monarchy in France that endured until the French Revolution. He also enforced uniformity of religion under the Gallican Catholic Church. His
