Henry IV (1367-1413), King of England (1399-1413), was born at Bolingbroke, Lincolnshire, the son of John of Gaunt and Blanche of Lancaster. He is the “Bolingbroke” of the Shakespeare plays. He was the cousin of Richard II, and one of the Lords Appellant in the “Merciless Parliament” of 1388. He found it advisable to leave England. Back in England in the 1390s he found sufficient favour with the king to be created the Earl of Hereford, but they fell out again over a quarrel between Henry and another of the lords appelant and Henry was banished.
In 1399, John of Gaunt died, and Richard confiscated the Lancastrian estates. Joined by others who had suffered under the king’s autocracy, he took advantage of Richard’s absence in Ireland and invaded. Richard was forced to abdicate and was incarcerated in Pontefract Castle, where he died – probably murdered - the following year.
For most of the next nine years he fought to keep his crown – against Richard’s supporters in 1400; against the Welsh under Owen Glendower (1400-1409); the Percy lords (1403-1408) and crushing a resurrection organised by Richard Scrope, the Archbishop of York in 1405. In 1408 Henry fell ill. There is conjecture that he had leprosy, though stress is as likely a cause. Certainly there was much discussion at the time that he was being punished for his execution of Scrope. It was to get steadily worse, and was to cause his death. Increasingly in the last nine years of his reign the kingdom was effectively ruled by his son, the future Henry V.
He had literary and musical tastes, was said to be chivalrous; was an able administrator and won fame as the foremost jouster of his age. He was a crusader, joining the Teutonic Knights in Lithuania in 1390, and, during the next three years, visited Prussia and made a pilgrimage to Jerusalem. His successes in the almost constant troubles of the first years of his reign are put down to ability, political acumen and the (well rewarded, no doubt) loyalty of his supporters. Like his grandfather, he was not against conciliation for the greater good.
It has been said that Henry suffered guilt for the forced abdication and regicide of Richard II, and the execution of Scrope; and had planned another pilgrimage to the Holy Land. As death became imminent, he had his bed moved into the Jerusalem Chamber in Westminster Abbey where he died in 1413.
The succession of his eldest son was accepted by all, a new dynasty was established; but, with the acts of 1399-1400, a precedent had been set that would lead to much turbulence in the years ahead.
