THE HUNDRED YEARS WAR 525 we have seen. Both kings then declared themselves of age and ruled well for a few years. In 1396 Richard married Charles's daughter and peace prevailed between the two realms. From 1392 Charles was insane most of the time, and some have thought that Richard's reason became affected also. At any rate, after eight years of constitutional govern- ment he suddenly in 1397 began to disregard Parliament and act as an absolute monarch and take vengeance on those who had opposed him during the period of his minority. Such conduct resulted in Richard's deposition in 1399 and in the throne being offered by Parliament to the son of John of Gaunt, who as Henry IV was the first king of The Lan- the House of Lancaster.

But John had promptly granted it again to his younger son, Philip. This Philip presently married the daughter of the Count of Flanders, and when her father died in 1384 they inherited not only Flanders, but also the counties of Bur- gundy, Nevers, Rethel, and Artois, Philip had had less
