The House of Leiningen is the name of an old German noble family whose lands lay principally in Alsace, Lorraine, Saarland, Rhineland, and the Palatinate. Various branches of this family developed over the centuries and ruled counties with Imperial immediacy. Origins The first count of Leiningen about whom anything definite is known was a certain Emich II (d. before 1138). He (and perhaps his father Emich I) built Leiningen Castle, which is now known as "Old Leiningen Castle" (German: Burg Altleiningen), around 1100 to 1110. Nearby Höningen Abbey was built around 1120 as the family's burial place. This family became extinct in the male line when Count Frederick I died about 1220. Frederick I's sister, Liutgarde, married Simon II, Count of Saarbrücken. One of Liutgarde's sons, also named Frederick, inherited the lands of the counts of Leiningen, and he took their arms and their name as Frederick II (d. 1237). He became known as a Minnesinger, and one of his songs was included in the Codex Manesse. Before 1212, he built himself a new castle called Hardenburg, about 10 kilometers south of Altleiningen. This was outside the county of Leiningen on the territory of Limburg Abbey, of which his uncle was the overlord (Vogt), which caused some trouble. His eldest son, Simon (c. 1204–1234), married Gertrude, heiress of the County of Dagsburg, bringing that property into the family. They had no children and Simon's two brothers inherited the county of Leiningen together: Frederick III (d. 1287) also inherited Dagsburg and Emich IV (d. c. 1276) Landeck Castle; he founded the town of Landau, but the Landeck branch extinguished with his grandson in 1290. Frederick III, who disliked sharing Leiningen castle with his brother, had a new castle built in 1238–41 about 5 kilometres northeast of Leiningen, called Neuleiningen Castle ("New Leiningen"). Frederick III's son, Frederick IV (d. 1316), had two sons, who divided the county into Leiningen-Dagsburg and Leiningen-Hardenburg. Line of Descent Note that different sources use different sequence numbers for some of the Counts. For consistency across sources, dates of birth and death are useful. Earliest Counts Emicho of Leiningen helped lead the German Crusade, 1096. His relationship to the others is unclear. Emich I was Count of Leiningen in 1127, but it is unclear when he died, or his relation to the other counts. Emich II is attested as Count of Leiningen in documents from 1143 to 1179
