The territory between Alamannia and Upper Burgundy was known as Argowe (modern Aargau, named for the Aare). The pertinence of this territory to either Alamannia or Upper Burgundy was disputed. The county of Raetia Curiensis was absorbed into Alamannia in the early 10th century. It comprised the Ringowe (Rheingau, named for the Rhine) and Retia proper. History Tribal kingdoms Originally a loose confederation of unrelated tribes, the Alemanni underwent coalescence or ethnogenesis during the 3rd century, and were ruled by kings throughout the 4th and 5th centuries until 496, when they were defeated by Clovis I of the Franks at the Battle of Tolbiac. The Alemanni during the Roman Empire period were divided into a number of cantons or goviae, each presided by a tribal king. But there appears to have been the custom of the individual kings uniting under the leadership of a single king in military expeditions. Some kings of the Alemanni of the 4th and 5th centuries are known by name, the first being Chrocus (died 306), a military leader who organized raids across the limes during the 3rd century. Chnodomarius (fl. 350) supported Constantius II in the rebellion of Magnentius. Chnodomarius was the leader of the Alemannic army in the battle of Strasbourg in 357. Macrian, Hariobaudes, Urius, Ursicinus, Vadomarius, and Vestralpus were Alemannic kings
