Why King Henry V name is different from all the earlier ones

Henry V (16 September 1386 – 31 August 1422), also called Henry of Monmouth, was King of England from 1413 until his death in 1422. Despite his relatively short reign, Henry's outstanding military successes in the Hundred Years' War against France made England one of the strongest military powers in Europe.[1] Immortalised in Shakespeare's "Henriad" plays, Henry is known and celebrated as one of the greatest warrior kings of medieval England.

Italy had political stability, wealth, and trade.
