Henry was born at Monmouth Castle in [[Wales]] in 1387 (though some historians have argued it was actually in 1386), and for that reason was sometimes known as "Henry of Monmouth" in his youth, especially before his father became king. Henry became embroiled in his country’s politics from an early age, being held at the court of Richard II for some time as a hostage for his father's good behavior (though he seems to have been treated well by Richard). After his father had overthrown Richard and been proclaimed king, Henry in turn was named Duke of Lancaster and [[Prince of Wales]] in 1400; within three years, at seventeen, he was fighting [[Owen Glendower]] and the powerful [[Percy]] family in his father’s name and was wounded at [[Shrewsbury]] in the battle that crushed the rebellion. | Henry was born at Monmouth Castle in [[Wales]] in 1387 (though some historians have argued it was actually in 1386), and for that reason was sometimes known as "Henry of Monmouth" in his youth, especially before his father became king.
