In the field of federal legislation, no significant change took place until the passage of the Hepburn Act of 1906, which was an amendment of the act of 1887.
James Hepburn succeeded in 1556 to his father's titles, lands and hereditary offices, including that of lord high admiral of Scotland.
The houses of Hepburn of Hailes, ancestor of Queen Mary's Bothwell; of the Huntly Gordons; and of the Kers of Ferniehirst and Cessford, rose into new importance; while the Huntlys and Argylls were entrusted with the maintenance of order among the fighting clans of the west and north.
Boyd, with some borderers, Hepburn and Ker of Cessford, seized the boy king, and Boyd had himself made governor, his son marrying the princess Mary, sister of James.
James and his leaders, Atholl and Huntly, with their Stewarts and Gordons, and the levies of burgesses, and the mounted gentry of Fife, encountered the wild border spearmen of Hepburn and Home and the Galloway men, the whole being led by Angus and the rebel prince at Sauchie burn, near Bannockburn.
