Shakespear - Henry IV

Sources
Shakespeare's primary source for Henry IV, Part 1, as for most of his chronicle histories, was Raphael Holinshed's Chronicles; the publication of the second edition in 1587 provides a terminus ad quem for the play. Edward Hall's The Union of the Two Illustrious Families of Lancaster and York appears also to have been consulted, and scholars have also supposed Shakespeare familiar with Samuel Daniel's poem on the civil wars.
Date and text
The play was entered into the Register of the Stationers Company on Feb. 25, 1598, and first printed in quarto later that year by stationer Andrew Wise. The play was Shakespeare's most popular, in print as well as on stage; new editions appeared in 1599, 1604, 1608, 1613, 1622, 1632, and 1639.
