Louis XIV of France
Louis XIV (Louis Dieudonné; 5 September 16381 September 1715), known as Louis
the Great  or the Sun King , was King of France from 14 May 1643 until his death in 1715.
His reign of 72 years and 110 days is the longest recorded of any monarch of a sovereign country in European history.
In the age of absolutism in Europe, Louis XIV's France was a leader in the growing centralisation of power.
Louis began his personal rule of France in 1661, after the death of his chief minister, the Italian Cardinal Mazarin.
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 Louis' minority.
By these means he became one of the most powerful French monarchs and consolidated a system of absolute monarchical rule in France that endured until the French Revolution.
Louis also enforced uniformity of religion under the Gallican Catholic Church.
His revocation of the Edict of Nantes abolished the rights of the Huguenot Protestant minority and subjected them to a wave of dragonnades, effectively forcing Huguenots to emigrate or convert, and virtually destroying the French Protestant community.
The Sun King surrounded himself with a dazzling constellation of political, military, and cultural figures such as Mazarin, Colbert, Louvois, the Grand Condé, Turenne, Vauban, Boulle, Molière, Racine, Boileau, La Fontaine, Lully, Charpentier, Marais, Le Brun, Rigaud, Bossuet, Le Vau, Mansart, Charles, Claude Perrault, and Le Nôtre.
During Louis' long reign, France was the leading European power, and it fought three major wars: the Franco-Dutch War, the War of the League of Augsburg, and the War of the Spanish Succession.
There were also two lesser conflicts: the War of Devolution and the War of the Reunions.
Warfare defined the foreign policy of Louis XIV, and his personality shaped his approach.
Impelled "by a mix of commerce, revenge, and pique"
, Louis sensed that warfare was the ideal way to enhance his glory.
In peacetime he concentrated on preparing for the next war.
He taught his diplomats that their job was to create tactical and strategic advantages for the French military.
Henry, Count of Looz
Henry( d. 2 August 1218), Count of Looz and Count of Duras, son of Gérard II, Count of Looz, and Adelaide of Gelderland, daughter of Henry I, Count of Guelders, and Agnes of Arnstein, daughter of Louis III of Arnstein.
Henry was Canon of St. Lambert in Liège, Provost of the Franciscans in Maastricht, and Provost of St. Alexander in Aschaffenburg.
Henry was Count of Looz for a few days in 1218, but died of poisoning.
He married Mechtild, daughter of Frederick III, Count of Vlanden.
Henry and Mechtild had one daughter:
He was succeeded as Count of Looz by his brother Arnold, and was the last recorded Count of Duras.
Otto-William, Count of Burgundy
Otto- William( 955/62 – 21 September 1026 AD), was Count of Mâcon, Count of Nevers, and the Count of Burgundy.
Rudolfe II, Count of Ivois
Rudolfe II( Rudolf, Raoul)( died 963), Count of Ivois and Count of Verdun( as Raoul), was son of Rudolfe I, Count of Ivois, and Eva. Rudolfe succeeded his father as Count of Ivois and was installed as Count of Verdun after the death of Otto, Duke of Lorraine, in 944.
After his death in 963, Godfrey the Prisoner was installed as count.
An estimate that his rule as Count of Verdun ended in 960 is based on a reference to Godfrey as a count in 960.
However, Godfrey was also count of Bidgau and Methingau from 959, so there is no reason to believe that Rudolfe was not count until his death in 963.
Rudolfe was overthrown as Count of Ivois by Étienne, Count of Porcien( year unknown), and replaced as Count of Verdun in 963 by Godfrey.
