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.
Roman–Gallic wars
223-193BC: After this came a concerted Roman policy aimed at conquering Gallic territories south of the Alps. Rome invaded the territory of the Insubres in 223BC, and took Clastidium, Acerrae and Mediolanum in 222BC. Rome fought Carthage in the Second Punic War (218-201BC), and the Gauls typically sided with Carthage. After the war, Rome took Bononia (196BC), Placentia (194 BC) and Mutina (193 BC). After this, many of the surviving Boii retreated north across the Alps to form a new state, Boihaemum.
