From the death of Lord Sinclair at Flodden, his widow, Dame Margaret Hepburn, held the Crown lands in Orkney and Zetland at a rent of £433, 6s. 8d., by successive Tacks for nearly 30 years without interruption, but not without disturbance. The Odallers knew too well the evils of alien rule; but a female ruler was a new indignity, and even in the second year of her widowhood (1515) they had elected as their leader and virtual Governor, James Sinclair the possessor (though illegitimate) of most of the wealth of his family, and the inheritor (as a born and bred Orkneyan) of all its popularity. On the plea of a general devastation by the English fleet in Orkney and Zetland, they withheld Lady Margaret’s Rents for three years (1523–5), forced her son Lord William to surrender her castle of Kirkwall and escape into Caithness (1528), and on his return next year with an army of Scots, defeated and took him prisoner at Summerdale (7th June 1529), slew his ally, John Earl of Caithness, with every man of his followers, beheaded Nicol Hall the Lawman, and took forcible possession of the Islands. The Scottish invasion, sanctioned as it was by the King’s Letters of Four Forms, cannot fairly be attributed to the private ambition of Earl John or his allies. On the other hand, it is equally improbable that Sinclair, the brother-in-law of the Queen Dowager of Scotland, would have risked his Court interest by heading an open rebellion against the King, or that the spirited and sagacious James V. would have pardoned wilful and violent rebels, or rewarded their leader with legitimation, lands and knighthood. The subject is beset with difficulties, but the most probable conclusion is, that the Orkneyans were deemed excusable in resisting to death a combination of circumstances so formidable to their independence, as the King’s reported purpose of giving a Feudal Lord to Odal Orkney, followed by the alliance of the Donatrix with Earl John, the zealous feudalizer of his own Earldom. James having asserted his dignity by renewing Lady Sinclair’s rights and by signing the dreaded but ineffective Feu Charter to his illegitimate brother, James Earl of Moray (1530–1), gave but one more feudal Grant, and that was to Sir James Sinclair (1535). This Grant containing every feudal right, and the first infraction of Odal succession by a clause of single primogeniture, was perhaps the purchase of the independence of the Odal leader—begged and accepted with a selfish inconsistency, mournfully explained by his madness and suicide within a year. But the King’s sagacity had found the pear not ripe—Odalism was sick, but not dead—the project was deferred, and no open attempt was renewed to feudalize the Islands for another generation.
