Caesar is one of the most, if not the most well known and famous Roman Emperors. He started off as a military general, and he showed great potential as such. The biggest military success of Caesar was the conquering of most of the territory where the Celtic tribes were living in continental Europe. Big portion of that territory was known by the Romans as Gaul, thus they used that term to identify numerous different Celtic tribes. Caesar played very well tactically when attacking the Celtic people, as he did not went into a full scale war with them, but was instead using surprise attacks on one tribe at a time, thus gradually conquering their territory. The word spread about this around Gaul, and the Gauls gathered a larger military in the short period of time they had, but it was too late. Caesar had already managed to defeat some of them, and had tactically superior military units, leading to eventual defeat of the Gauls and a great success for Caesar and Rome.
