The Raigne of King Edward the Third, commonly shortened to Edward III, is an Elizabethan play printed anonymously in 1596.
 It has frequently been claimed that it was at least partly written by William Shakespeare, a view that Shakespeare scholars have increasingly endorsed.
 The rest of the play was probably written by Thomas Kyd.
The Ur-Hamlet (the German prefix "Ur-" means "primordial") is a play by an unknown author, thought to be either Thomas Kyd or William Shakespeare.
 No copy of the play, dated by scholars to the second half of 1587, survives today.
 The play is known to have been staged in London, more specifically at The Burbages Shoreditch Playhouse as recalled by Elizabethan author Thomas Lodge.
 The play is known to have a character named Hamlet; the only other known character from the play is a ghost who cries, "Hamlet, revenge!"
An induction in a play is an explanatory scene, summary or other text that stands outside and apart from the main action with the intent to comment on it, moralize about it or in the case of dumb show to summarize the plot or underscore what is afoot.
 Typically, an induction precedes the main text of a play.
 Inductions are a common feature of plays written and performed in the Renaissance period, including those of Shakespeare.
 While Shakespeare plays do not typically have inductions, they are sometimes depicted as part of the device of the play within the play.
 Examples include the dumb show in "Hamlet" and the address to the audience by Puck in "A Midsummer Night's Dream".
 Another example, in "The Spanish Tragedy" by Thomas Kyd, is the introduction to that play by the ghost of Andrea who preps the audience by laying out the story to come.
 Likewise, Shakespeare's "The Taming of the Shrew" opens with induction scenes which involve characters watching the play proper.
Tamburlaine the Great is a play in two parts by Christopher Marlowe.
 It is loosely based on the life of the Central Asian emperor, Timur (Tamerlane/Timur the Lame, d. 1405).
 Written in 1587 or 1588, the play is a milestone in Elizabethan public drama; it marks a turning away from the clumsy language and loose plotting of the earlier Tudor dramatists, and a new interest in fresh and vivid language, memorable action, and intellectual complexity.
 Along with Thomas Kyd's "The Spanish Tragedy", it may be considered the first popular success of London's public stage.
Canadian content (CanCon, cancon or can-con) refers to the Canadian Radio-television and Telecommunications Commission (CRTC) requirements, derived from the Broadcasting Act of Canada, that radio and television broadcasters (including cable and satellite specialty channels) must air a certain percentage of content that was at least partly written, produced, presented, or otherwise contributed to by persons from Canada.
 It also refers to that content itself, and, more generally, to cultural and creative content that is Canadian in nature.
The Spanish Tragedy, or Hieronimo is Mad Again is an Elizabethan tragedy written by Thomas Kyd between 1582 and 1592.
 Highly popular and influential in its time, "The Spanish Tragedy" established a new genre in English theatre, the revenge play or revenge tragedy.
 Its plot contains several violent murders and includes as one of its characters a personification of Revenge.
 "The Spanish Tragedy" was often referred to (or parodied) in works written by other Elizabethan playwrights, including William Shakespeare, Ben Jonson, and Christopher Marlowe.
Edward III of England is the central character in the play "Edward III", sometimes attributed to William Shakespeare.
 He also appears as a boy in "Edward II" by Christopher Marlowe.
 Edward is also the protagonist of William Blake's early drama "Edward the Third", part of his "Poetical Sketches", published in 1783.
 George Bernard Shaw portrayed Edward for dramatic purposes as, in Shaw's preface to "The Six of Calais", "behaving himself like an unrestrained human being in a very trying situation".
Revenge tragedy (less commonly referred to as revenge drama, revenge play, or tragedy of blood) defines a genre of plays made popular in early modern England.
 Ashley H. Thorndike formally established this genre in his seminal 1902 article "The Relations of Hamlet to Contemporary Revenge Plays," which characterizes revenge tragedy "as a tragedy whose leading motive is revenge and whose main action deals with the progress of this revenge, leading to the death of the murderers and often the death of the avenger himself."
 Thomas Kyd's "The Spanish Tragedy" (c.1580s) is often considered the inaugural revenge tragedy on the early modern stage.
 However, more recent research extends early modern revenge tragedy to the 1560s with poet and classicist Jasper Heywood's translations of Seneca at Oxford University, including "Troas" (1559), "Thyestes" (1560), and "Hercules Furens" (1561).
 Additionally, Thomases Norton and Sackville's play "Gorbuduc" (1561) is considered an early revenge tragedy (almost twenty years prior to "The Spanish Tragedy").
 Other well-known revenge tragedies include William Shakespeare's "Hamlet" (c.1599-1602) and "Titus Andronicus" (c.1588-1593) and Thomas Middleton's "The Revenger's Tragedy" (c.1606).
Thomas of Woodstock and Richard the Second Part One are two names for an untitled, anonymous and apparently incomplete manuscript of an Elizabethan play depicting events in the reign of King Richard II.
 Attributions of the play to William Shakespeare have been nearly universally rejected, and it does not appear in major editions of the Shakespeare Apocrypha.
 The play has been often cited as a possible influence on Shakespeare's "Richard II", as well as "Henry IV, Parts 1" and "2", but new dating of the text brings that relationship into question.
Sir Thomas More is an Elizabethan play and a dramatic biography based on particular events in the life of the Catholic martyr Thomas More, who rose to become the Lord Chancellor of England during the Reign of Henry VIII.
 The play is considered to be written by Anthony Munday and Henry Chettle and revised by several writers.
 The manuscript is particularly notable for a three-page handwritten revision now widely attributed to William Shakespeare.
