Orgetorix

Orgetorix was the leader of the Helvetii people who in 61 BC devised the plan to migrate from Helvetian territory (modern-day Switzerland) to south-western Gaul (modern-day France). He also formed a conspiracy with Dumnorix of the Aedui, to whom he gave his daughter in marriage, and Casticus of the Sequani, to seize control of their respective tribes and between them rule Omnia Gallia. The Helvetii discovered this plot and tried to put him on trial, with the penalty of death by burning if found guilty. In an effort to avoid this fate, Orgetorix gathered an army of more than 10,000 of his followers and dependents, but while the Helvetii were raising their army against him he died, apparently by his own hand. The Helvetii adopted his migration plan, setting off in 58 BC, but were defeated and sent back to their homeland by Julius Caesar.
