===Alemannic and Frankish Alsace===
{{Main|Duchy of Alsace}}
In 357 CE, Germanic tribes attempted to conquer Alsace but they were rebuffed by the Romans.<ref name=":0" /> With the [[decline of the Roman Empire]], Alsace became the territory of the Germanic [[Alemanni]]. The Alemanni were agricultural people, and their Germanic language formed the basis of modern-day dialects spoken along the Upper Rhine ([[Alsatian dialect|Alsatian]], Alemannian, Swabian, Swiss). [[Clovis I|Clovis]] and the [[Franks]] defeated the Alemanni during the 5th century AD, culminating with the [[Battle of Tolbiac]], and Alsace became part of the [[Austrasia|Kingdom of Austrasia]]. Under Clovis' [[Merovingian]] successors the inhabitants were Christianized. Alsace remained under Frankish control until the [[Frankish realm]], following the [[Oaths of Strasbourg]] of 842, was formally dissolved in 843 at the [[Treaty of Verdun]]; the grandsons of [[Charlemagne]] divided the realm into three parts. Alsace formed part of the [[Middle Francia]], which was ruled by the eldest grandson [[Lothar I]].

Lothar died early in 855 and his realm was divided into three parts. The part known as [[Lotharingia]], or Lorraine, was given to Lothar's son. The rest was shared between Lothar's brothers [[Charles the Bald]] (ruler of the [[Western Francia|West Frankish]] realm) and [[Louis the German]] (ruler of the [[Eastern Francia|East Frankish]] realm). The Kingdom of Lotharingia was short-lived, however, becoming the [[stem duchy]] of [[Duchy of Lorraine|Lorraine]] in Eastern Francia after the [[Treaty of Ribemont]] in 880. Alsace was united with the other Alemanni east of the Rhine into the stem [[duchy of Swabia]].
