When Harold Harfagr (895) gave the conquered Jarldom of Orkney to Rognvald of Mære, the father of Rollo of Normandy, waiving his royal rights of Skatt and Lydskyld, he ostensibly reserved to his successors, the KINGS OF NORWAY, little more than a nominal sovereignty. But the royal rights and prerogatives, though dormant, were not the less real. The same King Harold exacted from the Islands a heavy Mulct for the death of his wayward son. King Erik Bloody-axe, and his wicked wife and sons, seized both lands and Skatts as their own (939). One King Olaf forced Christian Baptism on Sigurd Jarl and his men (995), and another compelled Thorfinn, the most powerful of the Orkney Jarls, to acknowledge himself as his Liegeman (1025). King Olaf Kyrre granted to his new city of Bergen the Monopoly of the trade with Zetland (1072). King Magnus Barefoot imprisoned the Jarls, and at his will resumed and restored the Jarldom (1098). King Sverrer punished Harald Jarl for rebellion by the Forfeiture of Zetland, and the Islanders by conditional Confiscation of the Odal of all rebels (1196). King Hacon IV. asked no leave of Magnus Jarl or his Odallers when he Valued and Taxed their Urislands (1263). Hacon V. appropriated the Revenue during the Jarl’s minority (1309), and Hacon VI. during disputed succession (1370); and every royal Sea-king, who ravaged the coasts of Britain or Ireland, mustered his fleet in the Orkneys, and received or enforced the Military Service of the Jarls. Thus from time to time had the Kings exacted in Orkney every royalty exigible in Norway, but at such long intervals, that we are apt to regard each rare assertion as a usurpation or new conquest, and to forget that Harald’s heirs were the Odal-born lords of Orkney, entitled to all royal rights whensoever they had will or strength to enforce them.
