Shakespeare's primary source for Henry VI, 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.
English Patriotism was at a high after the defeat of the Spanish Armada in 1588. This patriotism fed the fascination audiences had with history plays. The Henry VI trilogy was one of Shakespeare's first histories and was his most popular play during his lifetime.
