Oxfords argue that Stratford's celebrated playwright did not write any of the plays attributed to him. They suggest that he was merely a businessman and propose several contenders for authorship, namely an Edward de Vere.The earliest proof that William did indeed write 37 plays was Robert Greene’s criticism of the Bard in his Groatsworth of Wit, Bought with a Million of Repentance which attacked Shakespeare for having the nerve to compete with him and other playwrights in 1592 . Robert Greene made this quite clear by calling him "an upstart crow". This criticism was placed with the Stationers’ Registrar on the 20th of September, 1592.Proof that William was an actor comes from his own performances before Queen Elizabeth herself in 1594 and evidence of William's interest in theatre comes from the Bard's name being listed in 1594 and 1595 as a shareholder (part owner) of the Lord Chamberlain’s Company, a theatre company.The Bard's reputation as a poet is again confirmed in 1598, when Francis Meres attacked him as being "mellifluous" and described his work as honey-tongued, "sugared sonnets among his private friends" in his own Palladis Tamia of 1598.William's theatre presence is again confirmed by his name being recorded as one of the owners of the Globe theatre in 1599 and on May the 19th, 1603, he received a patent, titling him as one of the King’s Men (previously called the Chamberlain’s men) and a Groom of the Chamber by James I, the then King of England.

Macbeth which celebrates King James I ancestor Malcolm, is considered to have been written in part as appreciation for the King’s patronage. And as a potent form of royalist propaganda (it warned of the dangers of killing a King appointed like Ja...
