Henry IV (Bolingbroke) (1367-1413) was the King of England from 1399, the son of John of Gaunt.
In 1398 he was banished by Richard II for political activity, but returned 1399 to head a revolt and be accepted as king by Parliament. He was succeeded by his son Henry V.
He had difficulty in keeping the support of Parliament and the clergy, and had to deal with baronial unrest and Glendower's rising in Wales. In order to win support he had to conciliate the church by a law for the burning of heretics, and to make many concessions to Parliament.
