Helveti
The Helvetians are one of the Gaulese tribes who lived in present-day Switzerland and southern Germany and broke into the Roman republic of the first century BC. They came down to the south by the Germanic tribes and invaded Gaul. The Hai Dui, a pro-Roman tribe of Gallia, called for aid to Rome, and Julius Caesar intervened there, resulting in the Gallic War. Caesar had only 27,000 troops in the six corpses at the time, and the Helvetians reported that some 370,000 people, including women, had moved a great deal. Caesar succeeded in organizing two new corpses and launching war with the Hai Dui and chasing them back to Switzerland. The Helvetia Republic, founded in Switzerland in 1798, is named after the tribe.
