Their principles on this head were too fast rooted to admit of any sudden or violent alteration.
The revolution in England proved likewise the occasion of an insurrection in Wales.

Owen Glendour, or Glendourduy, descended from the ancient princes of that country, had become obnoxious on account of his attachment to Richard: and Reginald, Lord Gray of Ruthyn, who was closely connected with the new king, and who enjoyed a great fortune in the marches of Wales, thought the opportunity favorable for oppressing his neighbor, and taking possession of his estate.

[***] Glendour, provoked at the injustice, and still more at the indignity, recovered possession by the sword; [****] Henry sent assistance to Gray; [*****] the Welsh took part with Glendour: a troublesome and tedious war was kindled, which Glendour long sustained by his valor and activity, aided by the natural strength of the country, and the untamed spirit of its inhabitants.
