|This article is about the unit in Age of Empires II HD: The Forgotten. For the unit in Age of Mythology, see Jarl (Age of Mythology).|
Prior to the Definitive Edition, the Jarl was represented by a Tarkan, but with better stats (he was shown carrying a torch). In the Definitive Edition, he has a unique appearance and chucks axes which deal melee damage at range, similar to the Throwing Axeman. Like other cavalry, the Jarl is affected by all upgrades that affect cavalry as well as any other bonuses that affect them. As a hero, he cannot be converted and can regenerate health.
A notable appearance of a Jarl is in the York scenario, as part of a landing party that must establish a base in the British Isles, before the Great Heathen Army arrives. He should be used to fight Monks, as he cannot be converted and can also quickly kill them with his strong attack.
