Military campaigns of Julius Caesar
The military campaigns of Julius Caesar constituted both the Gallic War (58 BC-51 BC) and Caesar's civil war (50 BC-45BC) in 59 BC, which had been highly controversial. The Gallic War mainly took place in what is now France. In 55 and 54 BC, he invaded Britain, although he made little headway. The Gallic War ended with complete Roman victory at the Battle of Alesia. This was followed by the civil war, during which time Caesar chased his rivals to Greece, decisively defeating them there. He then went to Egypt, where he defeated the Egyptian pharaoh and put Cleopatra on the throne. He then finished off his Roman opponents in Africa and Hispania. Once his campaigns were over, he served as Roman dictator until his assassination root on March 15, 44 BC. These wars were critically important in the transition of the Roman Republic into the Roman Empire.
Segni (tribe)
The Segni (sometimes Segui) were a tribe living in Belgic Gaul when Julius Caesar's Roman forces entered the area in 57 BCE. They are known from his account of the "Gallic War". They were one of a group of tribes listed by his local informants as the "Germani" of Belgian Gaul, along with the Eburones, Condrusi, Paemani (or Caemani), and Caeroesi (or Caeraesi). The Segni do not appear in the first listing of the Germani, which was a listing of Germani sending men to fight Caesar. But they appear in a later mention, after the defeat of the Eburones: The Segui and Condrusi, of the nation and number of the Germans ["Germani"], and who are between the Eburones and the Treviri, sent ambassadors to Caesar to entreat that he would not regard them in the number of his enemies, nor consider that the cause of all the Germans on this side the Rhine was one and the same; that they had formed no plans of war, and had sent no auxiliaries to Ambiorix. Caesar, having ascertained this fact by an examination of his prisoners, commanded that if any of the Eburones in their flight had repaired to them, they should be sent back to him; he assures them that if they did that, he will not injure their territories.
