The Kingdom of Lotharingia (Lotharingian: Koningryk Lotharingen), also known simply as Lotharingia, is a sovereign state and constitutional monarchy located in Western Europe, predominated centered in the northwestern Lowlands region. The Lotharingian identity was only recently established following the Succession War of Limbourg, where Duke John I of Brabant together with Loon and Berg, and several other regional allies, were able to defeat the Electorate of Cologne and her allies.

Following the extensive political efforts of the Brabantine dukes, John II and John III, the ruling family of the state were able to enforce their title as Duke of Lotharingia over a time of several years. Eventually, they would successfully push for and acquire the promotion of their title to that of an Archduchy by Papal decree in 1318.


In 959, the East Frankish king Otto I of Germany elevated Count Godfrey of Jülich to the rank of duke of Lower Lorraine. In 962, the duchy became an integral part of the Holy Roman Empire, where Godfrey's successors of the ducal Ardennes-Verdun dynasty also ruled over the Gau of Brabant. Here, the counts of Leuven rose to power, when about the year 1000 Count Lambert I the Bearded married Gerberga, the daughter of Duke Charles of Lower Lorraine, and acquired the County of Brussels. About 1024 southernmost Brabant fell to Count Reginar V of Mons (Bergen, later Hainaut), and Imperial lands up to the Schelde river in the west came under the rule of the French Counts Baldwin V of Flanders by 1059. Upon the death of Count Palatine Herman II of Lotharingia in 1085, Emperor Henry IV assigned his fief between the Dender and Zenne rivers as the Landgraviate of Brabant to Count Henry III of Leuven and Brussels.

About one hundred years later, in 1183/1184, Emperor Frederick I Barbarossa formally established the Duchy of Brabant and created the hereditary title of Duke of Brabant in favour of Henry I of Brabant, son of Count Godfrey III of Leuven. Although the original county was still quite small - and limited to the territory between the Dender and Zenne rivers, situated to the west of Brussels - from the 13th century onwards its name came to apply to the entire territory under control of the dukes.

In 1190, after the death of Godfrey III, Henry I also became Duke of Lower Lotharingia. By that time the title had lost most of its territorial authority. According to protocol, all his successors were thereafter called Dukes of Brabant and Lower Lotharingia (often called Duke of Lothier).

After the Battle of Worringen in 1288, the dukes of Brabant also acquired the Duchy of Limburg and the lands of Overmaas (trans-Meuse).

Lotharingian Unification

After the death of John I of Brabant, son John II of Brabant decided that he would again pursue the policy of Lotharingification. This was the policy of reunifying all the lands that once used to belong to the Duchy of Lotharingia. This process was started in 1295 when John II bought the rights for the small lordship of Myerebeke and then in 1299 continued with Duke John II claiming the vacant throne of Zeeland and Holland.

Council of Heyst

On the 21st of March 1312 the Duke of Brabant and Limburg, Count of Holland, Zeeland, Dalhem and Aalst signed the Charter of Heyst. This Charter with its rights and local representation is often referred to as a Constitution, Some calling it the "Heyst Constitution". This is even the first charter to give estates the right to participate and make democratic decisions. and two new states joining this Union shortly after in 1314 but with more autonomy these states being the County of Loon and Hainaut. These two states still having their own Monarchy and city rights, and even over their local disputes even if anyone can request higher trial without delay. Although for these two states the trial follows local law and not Council adopted law.
