Celtic warfare
The "Gallic Wars" were a series of military campaigns waged by the Roman proconsul Julius Caesar against Gallic tribes, lasting from 58 BC to 51 BC. The Romans would also raid Britannia and Germania, but these expeditions never developed into full-scale invasions. The Gallic Wars culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul. The wars paved the way for Caesar to become the sole ruler of the Roman Republic.
Punic Wars
The Punic Wars were a series of three wars fought between Rome and Carthage from 264 BC to 146 BC. At the time, they were some of the largest wars that had ever taken place. The term "Punic" comes from the Latin word "Punicus" (or "Poenicus"), meaning "Carthaginian", with reference to the Carthaginians' Phoenician ancestry.
