James could succeed in these measures, but his plan for uniting the two kingdoms into one, Great Britain, though supported by the wisdom and eloquence of Bacon, was frustrated by the jealousies of both peoples. Persons born after James's accession (the _post nati_) were, however, admitted to equal privileges in either kingdom (1608). In 1610 James had two of his bishops, and Spottiswoode, consecrated by three English bishops, but he did not yet venture to interfere with the forms of Presbyterian public worship. In 1610 James established two Courts of High Commission (in 1615 united in one Court) to try offences in morals and religion. The Archbishops presided, laity and clergy formed the body of the Court, and it was regarded as vexatious and tyrannical. The same terms, to be sure, would now be applied to the interference of preachers and presbyteries with private life and opinion. By 1612 the king had established Episcopacy, which, for one reason or another, became equally hateful to the nobles, the gentry, and the populace. James's motives were motives of police. Long experience had taught him the inconveniences of presbyterial government as it then existed in Scotland. To a Church organised in the presbyterian manner, as it has been practised since 1689, James had, originally at least, no objection. But the combination of "presbyterian Hildebrandism" with factions of the turbulent _noblesse_; the alliance of the Power of the Keys with the sword and lance, was inconsistent with the freedom of the State and of the individual. "The absolutism of James," says Professor Hume Brown, "was forced upon him in large degree by the excessive claims of the Presbyterian clergy." Meanwhile the thievish Border clans, especially the Armstrongs, were assailed by hangings and banishments, and Ulster was planted by Scottish settlers, willing or reluctant, attracted by promise of lands, or planted out, that they might not give trouble on the Border.
