Soon after the French had carried on these hostile movements, (p. 187) their King made a solemn league with Owyn Glyndowr, as an independent sovereign, acknowledging him to be Prince of Wales. Owyn dated his princedom from the year 1400, and assumed the full title and authority of a monarch.[186] In this year he commissioned Griffin Young his chancellor, and John Hangmer, both "his beloved relatives," to treat with the King of France, in consideration of the affection and sincere love which that illustrious monarch had shown _towards him_ and _his subjects_.[187] This commission is dated "Doleguelli, 10th May, A. D. 1404, and in the fourth year of our principality." In conformity with its tenour, a league was made and sworn to between the ambassadors of "_our illustrious and most dread lord, Owyn, Prince of Wales_," and those of the King of France. That sovereign signed the commission (p. 188) on the 14th of June; and the league was sealed in the chancellor's house at Paris, on the 14th July. Its provisions are chiefly directed against "Henry of Lancaster." [Footnote 186: Owyn does not, however, seem to have exercised the princely prerogative of coining money. Indeed, no Welsh coin of any date is known to have been ever in existence. Thomas Thomas, the Welsh antiquary, says that a coin (or Dr. Stukeley's impression from a coin) of King Bleiddyd is now in the Cotton museum, of a date above nine hundred years before Christ; and that there are others of Monagan about the year one hundred and thirty before the Christian era. A search for them, it is presumed, would be fruitless.] [Footnote 187: The words in italics are in the original "erga nos et _subditos_ nostros." "Illustris et metuendissimi domini nostri Owini Principis Walliarum."--See Rymer.]
