Changes

Henry IV: He is the initial king shown in his last days. His kingdom is beset with strife and he seems unable to placate his country. A lot of this has to do with how he came to power, having effectively deposed Richard II and many rebellions resulted because of the issue of succession to the English throne and rebellions and war by Scotland and Wales. <ref>For more on Henry IV and the troubles surrounding his reign, see: Dodd G and Biggs D (eds) (2003) <i>Henry IV: The Establishment of the Regime, 1399-1406</i>.

Thomas: The younger son of Henry IV is shown as a would-be king trying to please his father and also jealous of his older brother Hal (or Henry V). He dies in battle, showing poor judgment in launching a battle that did not need to be fought. <ref>For more on Thomas, see: Allmand CT (1997) <i>Henry V</i>. New ed. Yale English monarchs.

Henry V: He is depicted is initially being immature and not wanting to be king. However, initially he wants to support his brother and after his brother's death he sees it is his responsibility in correcting the mistakes of his father by uniting the kingdom. He does not want war with France, but feels he must act after believing French agents attempted to kill him.<ref>See also: Allmand CT (1997) <i>Henry V</i>. New ed. Yale English monarchs.

William Gascoigne: Initially, he was shown as a trusted adviser who could help the young king navigate politics in the early 14th century. However, he was later depicted as someone more interested in manipulating the king to launch a war that was not needed simply to advance his own interests. <ref>For more on the historical Gascoigne, see: Paxman J (2007) <i>The English: A Portrait of a People</i>.
