A CRITICAL INTRODUCTION
The history of this period dating from the reign of Richard Il to the defeat of Richard III at Bosworth Field in 1485 was dramatized in two tetralogies. The first includes Richard Il (1595), the two Henry IV plays (1597-98), and Henry V(1599)(Here and elsewhere the generally accepted dates of composition are given.) In these plays Shakespeare presented the tragic fortunes of Richard Il which culminated in his deposition and murder: the rebellions which harassed the reign of the usurper and regicide, Henry IV; and the triumph of Henry V, who escaped punishment in this world for the sins of his father because he engaged English forces in a war against a foreign enemy, France, winning his famous victories. The second tetralogy includes the three Henry VI plays (1590-92)(Whether Shakespeare was actually the sole author of the Henry VI plays is still disputed, but there is little doubt that they are substantially his works.) and Richard III ( 1593). Obviously, the latter plays predate those comprising the first tetralogy, but there is sufficient evidence, external and internal, that Shakespeare, like his contemporaries,saw in the deposition of Richard Il, a lawful anointed ruler, the source of England's troubles during the entire period. This is a point worth keeping in mind because it makes understandable why the descendants of Lancastrian Henry IV as well as the members of the Yorkist party should be made to suffer grievously.
