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.
Netherlands in the Roman era
During the Gallic Wars, the Belgic area south of the Oude Rijn and west of the Rhine was conquered by Roman forces under Julius Caesar in a series of campaigns from 57 BC to 53 BC. He established the principle that this river, which runs through the Netherlands, defined a natural boundary between Gaul and Germania magna. But the Rhine was not a strong border, and he made it clear that there was a part of Belgic Gaul where many of the local tribes were "Germani cisrhenani", or in other cases, of mixed origin. The approximately 450 years of Roman rule that followed would profoundly change the area that would become the Netherlands. Very often this involved large-scale conflict with the "free Germans" over the Rhine.
