Alemanni

The Alemanni or Alamanni were a confederation of Germanic tribes on the Upper Rhine River during the 1st millennium. They are first mentioned by Cassius Dio in the context of the campaign of Roman emperor Caracalla of 213 AD, the Alemanni captured the Agri Decumates in 260 AD, and later expanded into present-day Alsace and northern Switzerland, leading to the establishment of the Old High German language in those regions, which by the 8th century were collectively referred to as Alamannia.

In 496 AD, the Alemanni were conquered by the Frankish leader Clovis and incorporated into his dominions. Mentioned as still pagan allies of the Christian Franks, the Alemanni were gradually Christianized during the 7th century. The Lex Alamannorum is a record of their customary law during this period. Until the 8th century, Frankish suzerainty over Alemannia was mostly nominal. However, after an uprising by Theudebald, the Duke of Alamannia, Carloman executed the Alamannic nobility and installed Frankish dukes.

As the Carolingian Empire weakened in later years, the Alemannic counts became almost independent, and a struggle for supremacy took place between them and the Bishopric of Constance. The chief family in Alamannia was that of the counts of Raetia Curiensis, who were sometimes called margraves, and one of whom, Burchard II, established the Duchy of Swabia, which was recognized by Henry the Fowler in 919 AD and became a stem duchy of the Holy Roman Empire.

The area settled by the Alemanni corresponds roughly to the area where Alemannic German dialects remain spoken, including German Swabia and Baden, French Alsace, German-speaking Switzerland, Liechtenstein and Austrian Vorarlberg. The French-language name of Germany, Allemagne, is derived from their name, from Old French aleman(t), and from French was loaned into a number of other languages, including Middle English, which commonly used the term Almains for Germans. Likewise, the Arabic name for Germany is ألمانيا (Almanya), the Turkish is Almanya, the Catalan is Alemanya, the Spanish is Alemania, the Portuguese is Alemanha, the Welsh is Yr Almaen and the Persian is آلمان (Alman).
