in 1753. This etymology has remained the standard derivation of the name. An alternative suggestion proposes derivation from *alah "sanctuary". Walafrid Strabo in the ninth century remarked, in discussing the people of Switzerland and the surrounding regions, that only foreigners called them the Alemanni, but that they gave themselves the name of Suebi. The Suebi are given the alternative name of Ziuwari (as Cyuuari) in an Old High German gloss, interpreted by Jacob Grimm as Martem colentes ("worshippers of Mars"). Annio da Viterbo a scholar and historian of the 15th century claimed the Alemanni had their name from the hebrew language, as in hebrew the river Rhine was translated into Mannum and the people who live at its shores were called Alemannus. This was refuted by Beatus Rhenanus, a humanist of the 16th century.

In retribution, Caracalla then led the Legio II Traiana Fortis against the Alemanni, who lost and were pacified for a time. The legion was as a result honored with the name Germanica. The fourth-century fictional Historia Augusta, Life of Antoninus Caracalla, relates (10.5) that Caracalla then assumed the name Alemannicus, at which Helvius Pertinax jested that he should really be called Geticus Maximus, because in the year before he had murdered his brother, Geta. Through much of his short reign, Caracalla was known for unpredictable and arbitrary operations launched by surprise after a pretext of peace negotiations. If he had any reasons of state for such actions, they remained unknown to his contemporaries. Whether or not the Alemanni had been previously neutral, they were
