The JARL held not only the largest Odal lands in his Jarldom, but the sovereign power in a secondary and delegated degree. None of these rights, however, descended to him by the Odal-ræd, which constituted the immemorial title of his subjects. The Odal of his fathers lay in the Norwegian Jarldom of Mære. Rognvald became Jarl of Orkney (895), only by the gift of King Harald Harfagr; and his successors owed their lands and dignities to similar royal grants, and their powers to the sanction of the Althing. But though only the Lydskylldr or Liegeman of the King, the Orkneyar Jarl was not only exempted from the customary Lydskylld of Norwegian Lendermen; but in consideration of exposure to piracy, was permitted to retain the royal Skatt paid by the Odallers for the exigencies of the Jarldom, and there was little to remind him of his own subjection, unless when face to face with the King, nor of the Odallers’ independence, except their rare refusal to join him in a Viking-för. When at home he passed, like the kings of Norway, from one Bordland, Böl or _Guestquarter_ to another, receiving most of his revenues in kind for the ordinary necessities of his household, and defraying his wasteful hospitalities at the cost of his Saxon or Celtic neighbours impartially. With the Skatt of the Odallers, and the Landskylld of his tenants, he kept up a fleet of restless rovers, ever ready for a provident Haust-Viking on the coasts of England, Scotland, or Ireland, for their Jol-feasts and winter cheer, or a thrifty Vörviking, when their exuberant carouses threatened a short supply of beeves and ale. At his death, his Jarldom and its rights were divided, compromised or contested by his heirs, till but one or two remained to enjoy the impoverished inheritance. Nine generations of this Northman race of Rognvald had ruled the Jarldom by a sort of prescriptive Odal-ræd, sometimes extending their authority over half of Scotland and Ireland—sometimes struggling for their insular domains—but in the twelfth century, the growing power of the Scoto-Celtic Crown had shorn them of their southern conquests of Moray, Ross, Inverness, Man, and the Hebrides. Erlend IV., the last heir male of his line, shared the Jarldom with St. Rognvald (the first instance of succession through a female—the founder of Kirkwall and its stately kirk, in honour of his maternal uncle Magnus Jarl, the Saint and Martyr), and on their closely consecutive deaths (1154–8), the sole succession devolved upon HARALD II., son of the Countess Margaret of Orkney and the Scottish Earl Madad of Athol. Harald Madadson was the founder of the shortest but most disastrous of Orkneyan dynasties. By his opposition to the Birkbeinar revolution, which made Sverrer Sovereign of Norway, Harald Jarl forfeited Zetland (1196), never to be again formally or permanently united to Orkney; and after two wars of mutual barbarity and reprisals, he was compelled to do homage to William the Lion for all Cathnes to the Oikel (1198).
