The Imperial commanders-in-chief during the reign of Holy Roman Emperor Maximilian I did hold the title "Kriegsherr", of which the direct translation was "warlord", but they were not warlords in the sense of the word today. Other warlords could be found in the British Isles during the Middle Ages and up into the Early Modern period; such examples include Brian Boru of Ireland and Guthrum of the Danelaw, who was the commander of the Great Heathen Army and nearly conquered all of England, Alfred of Anglo-Saxon England, first man to unify the Anglo-Saxon kingdoms of Europe, although it would not be completed until Edward the Elder's reign, in which he conquered the last remnants of the Danelaw.
