Long ago, there was a land. 
Long ago, a land was made. 
This land was a big piece of an empire. Later, the land was split in two. One part was the north. The other part was the south.
The land changed its name over time. People called it Lorraine. It was a very important place for many kings.
Long ago, a land called Lotharingia was made. It began in the year 855. A king named Lothair II ruled this land. His name gave the land its name. 
Lotharingia was a special place. It included parts of France and Germany. It also had parts of Belgium and the Netherlands.
Lotharingia was a special land that existed a long time ago. It was a kingdom in Europe during the middle ages. This region lived between other strong lands. Because of its location, many kings wanted to rule it. The name Lotharingia means "the land of Lothair." It came from the name of its first king, Lothair II. 
This kingdom started because of a large empire called the Carolingian Empire. A leader named Louis the Pious had three sons. After he died, the empire was split into parts. In 855, a treaty at a place called Prüm divided the land again. Lothair II received the middle part of the empire. This land was a long strip of territory. It stretched from the North Sea all the way to Italy.
History shows that Lotharingia changed many times. In 870, the Treaty of Meerssen split the kingdom into two pieces. One piece went to West Francia and the other to East Francia. Later, the land was joined back together by the Treaty of Ribemont in 880. By the year 903, it was no longer a kingdom. Instead, it became a duchy. A duchy is a land ruled by a person called a duke. 
Lotharingia covered many places we know today. It included the region of Lorraine in France. It also included Luxembourg and most of Belgium. Some parts of the Netherlands and Germany were there too. Between 959 and 965, the land was split into two duchies. The northern part was called Lower Lotharingia. The southern part was called Upper Lotharingia.
The story of Lotharingia connects to the world we see now. The name of the land changed as years passed. People began to use the Latin name to create new words. This led to the name "Lorraine" used in France today. Some parts of the land became part of the German Empire in 1871. Later, these areas became part of France again. Even though the kingdom is gone, its name lives on in many places.
Lotharingia was a historical region and a political entity in early medieval Europe. It existed from the middle of the 9th century to the mid-10th century. The territory was located in a central position between other major powers. It included parts of what are now France, Luxembourg, Switzerland, Germany, Belgium, and the Netherlands. The name Lotharingia means "the land of Lothair." This name comes from its first ruler, King Lothair II. 
The origins of Lotharingia lie in the division of the Carolingian Empire. In 817, Emperor Louis the Pious planned to divide his empire among his three sons. However, a fourth son, Charles the Bald, was born later. This led to a decade of civil war between the brothers. In 843, the Treaty of Verdun settled the conflict. The eldest son, Lothair I, received a long strip of land. This territory stretched from the North Sea to southern Italy. Historians sometimes call this the "Lotharingian axis."
In 855, the Treaty of Prüm changed the borders again. As Lothair I was dying, he divided his kingdom among his three sons. The middle son, Lothair II, received the northern territories. This new kingdom was known as Lotharingia. It lacked ethnic or linguistic unity, meaning the people did not share the same language or culture. Lothair II ruled from the city of Aachen. He did not travel far outside his kingdom during his reign.
Lotharingia faced many changes in status after Lothair II died in 869. He left no legitimate children to inherit his throne. His uncles, the kings of East and West Francia, decided to divide the land. The Treaty of Meerssen in 870 split the kingdom between them. The western half went to West Francia, and the eastern half went to East Francia. This meant the united kingdom of Lotharingia ceased to exist for a time. Later, the Treaty of Ribemont in 880 reunited the territory. 
By the year 903, Lotharingia was no longer a kingdom. It was organized as a duchy, which is a territory ruled by a duke. The kings of East Francia appointed dukes to manage the region. This period was marked by shifting loyalties among the nobility. For example, in 911, some nobles voted to attach the duchy to West Francia. However, in 925, others elected Henry the Fowler as their king. This constant struggle showed that Lotharingia was a highly contested prize for neighboring rulers.
Between 959 and 965, the region underwent a major administrative reorganization. Under the direction of Bruno the Great, the duchy was divided into two parts. The southern half became known as Upper Lotharingia. The northern half became known as Lower Lotharingia.
The history of Lotharingia is connected to many modern names and borders. The Latin name Lotharingia gave rise to the French word "Lorraine." In 1871, after the Franco-Prussian War, parts of the region became the province of Alsace-Lorraine in the German Empire. These territories returned to France after World War I. Today, much of this historic land is part of the Grand Est region in France. The story of Lotharingia shows how ancient political borders can shape the identity of modern nations.
