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.
Julius Caesar
Many rulers in history became interested in the historiography of Caesar. Napoleon III wrote the scholarly work "Histoire de Jules César", which was not finished. The second volume listed previous rulers interested in the topic. Charles VIII ordered a monk to prepare a translation of the "Gallic Wars" in 1480. Charles V ordered a topographic study in France, to place The Gallic Wars in context; which created forty high-quality maps of the conflict. The contemporary Ottoman sultan Suleiman the Magnificent catalogued the surviving editions of the "Commentaries", and translated them to Turkish language. Henry IV and Louis XIII of France translated the first two commentaries and the last two respectively; Louis XIV retranslated the first one afterwards.
