There is mounting evidence that Rome was active in Ireland, such as the Roman fort in Drumanagh and burials on Lambay Island.
It is easy to show Ireland’s connection to Roman warfare. However, this theory disregards the large amount of evidence that the Goidels of Ireland were in constant communication with Britain and Continental Europe throughout the earlier periods, and would have evolved the same styles of warfare as those regions to deal with them. Many scholars believe that during the Viking Age the Scandinavian raiders and settlers brought into Ireland a new style of warfare, introducing concepts like total war and formation fighting into Ireland, which previously fought in small raids as its form of waging war.
