William Shakespeare (baptised April 26 1564, died April 23 1616) was an English poet and playwright widely regarded as the greatest writer of the English language, one of the greatest in Western literature, and the world's preeminent dramatist. Prevailing scholarly opinion is that, as regards surviving literature, he was sole or principal author of thirty-six plays, joint author of two, and part author of at least four, and author of two lengthy narrative poems, a sequence of 154 sonnets, and an uncertain number of other short poems, and some of his work is now lost. Some scholars differ on details, but theories that the works were actually written by Bacon, Marlowe, Oxford, Derby or a committee are regarded as fringe. A popular writer in his own lifetime, Shakespeare's reputation became increasingly celebrated after his death and his work has been admired by prominent cultural figures through the centuries. Shakespeare is the most quoted writer in the literature and history of the English-speaking world. He is often considered to be England's "national poet" and is sometimes referred to as the "Bard of Avon" (or simply "The Bard")  or the "Swan of Avon".
Shakespeare is believed to have produced most of his work between 1586 and 1616, although the exact dates are uncertain. He is among the very few playwrights who have excelled in both tragedy and comedy, and his plays combine popular appeal with complex characterisation, poetic grandeur and philosophical depth.
Shakespeare's works have been translated into every major living language, and his plays are continually performed all around the world. In addition, many quotations and neologisms from his plays have passed into everyday usage in English and other languages. Over the years, many people have speculated about Shakespeare's life, raising questions about his sexuality, religious affiliation, and the authorship of his works.
William Shakespeare (also spelled Shakspere, Shaksper, Shaxper, and Shake-speare, due to the fact that spelling in Elizabethan times was not fixed and absolute) was born in Stratford-upon-Avon in April 1564, the son of John Shakespeare, a successful glover and alderman from Snitterfield, and of Mary Arden, a daughter of the gentry. His birth is assumed to have occurred at the family house on Henley Street. Shakespeare's christening record dates to April 26 of that year. Because christenings were performed within a few days of birth, tradition has settled on April 23 as his birthday. This date provides a convenient symmetry because Shakespeare died on the same day, April 23 (May 3 on the Gregorian calendar), in 1616.
Shakespeare probably attended King Edward VI Grammar School in central Stratford. While the quality of Elizabethan-era grammar schools was uneven, the school probably would have provided an intensive education in Latin grammar and literature. It is presumed that the young Shakespeare attended this school, since as the son of a prominent town official he was entitled to do so for free (although his attendance cannot be confirmed because the school's records have not survived). At the age of eighteen, he married Anne Hathaway, who was twenty-six, on November 28, 1582. One document identified her as being "of Temple Grafton," near Stratford, and the marriage may have taken place there. Two neighbours of Hathaway posted bond that there were no impediments to the marriage. There appears to have been some haste in arranging the ceremony, presumably because Anne was three months pregnant.
On May 26, 1583, Shakespeare's first child, Susanna, was baptised at Stratford. Twin children, a son, Hamnet, and a daughter, Judith, were baptised on February 2, 1585. Hamnet died in 1596.
After his marriage, Shakespeare left few traces in the historical record until he appeared on the London theatrical scene. Indeed, the period from 1585 (when his Twin children were born) until 1592 are known as Shakespeare's "lost years" because no evidence has survived to show exactly where he was or why he left Stratford for London. A number of stories are given to account for Shakespeare's life during this time, including that Shakespeare got in trouble for poaching deer, that he worked as a country school teacher, and that he minded the horses of theatre patrons in London. There is no direct evidence to support any of these stories and they all appeared to have started after Shakespeare's death.
London and theatrical career
By 1592, Shakespeare was a playwright in London; he had enough of a reputation for Robert Greene to denounce him as "an upstart crow, beautified with our feathers, that with his Tygers hart wrapt in a Players hyde, supposes he is as well able to bombast out a blanke verse as the best of you: and being an absolute Johannes factotum, is in his owne conceit the onely Shake-scene in a countrey." (The italicised line parodies the phrase, "Oh, tiger's heart wrapped in a woman's hide" which Shakespeare wrote in Henry VI, part 3.)
By late 1594, Shakespeare was an actor, writer and part-owner of a playing company, known as the Lord Chamberlain's Men — like others of the period, the company took its name from its aristocratic sponsor, in this case the Lord Chamberlain. The group became popular enough that after the death of Elizabeth I and the coronation of James I (1603), the new monarch adopted the company and it became known as the King's Men. Shakespeare's writing shows him to indeed be an actor, with many phrases, words, and references to acting, but there isn't an academic approach to the art of theatre that might be expected.
By 1596, Shakespeare had moved to the parish of St. Helen's, Bishopsgate, and by 1598 he appeared at the top of a list of actors in Every Man in His Humour written by Ben Jonson. By 1598, his name began to appear on the title pages of his plays.
There is a tradition that Shakespeare, in addition to writing many of the plays his company enacted, and being concerned as part-owner of the company with business and financial details, continued to act in various parts, such as the ghost of Hamlet's father, Adam in As You Like It, and the Chorus in Henry V.
He appears to have moved across the Thames River to Southwark sometime around 1599. By 1604, he had moved again, north of the river, where he lodged just north of St Paul's Cathedral with a Huguenot family named Mountjoy. There, he helped arrange a marriage between the Mountjoys' daughter and their apprentice Stephen Bellott. Bellott later sued his father-in-law for defaulting on part of the promised dowry, and Shakespeare was called as a witness.
Various documents recording legal affairs and commercial transactions show that Shakespeare grew rich enough during his stay in London to buy a property in Blackfriars, London and own the second-largest house in Stratford, New Place.
Shakespeare's last two plays were written in 1613, after which he appears to have retired to Stratford. He died on April 23 1616, aged fifty-two, on his birthday, if the speculation that he was born on April 23 is correct. He was married to Hathaway until his death and was survived by his two daughters, Susanna and Judith. Susanna married Dr John Hall, but he has no direct descendants alive today. Shakespeare is buried in the chancel of Holy Trinity Church in Stratford-upon-Avon. He was granted the honour of burial in the chancel not on account of his fame as a playwright but for purchasing a share of the tithe of the church for £440 (a considerable sum of money at the time). A monument placed by his family on the wall nearest his grave features a bust of him posed in the act of writing. Each year on his claimed birthday, a new quill pen is placed in the writing hand of the bust.
He is believed to have written the epitaph that is engraved on his tombstone:
- Good friend, for Jesus' sake forbear,
- To dig the dust enclosèd here.
- Blest be the man that spares these stones,
- And cursed be he that moves my bones.
Some of Shakespeare's plays have the reputation of being among the greatest in the English language and in Western literature. He wrote tragedies, histories, comedies and romances, which have been translated into every major living language in addition to being continually performed around the world.
As was normal in the period, Shakespeare based many of his plays on the work of other playwrights and reworked earlier stories and historical material. For example, Hamlet (c. 1601) is probably a reworking of an older, lost play (the so-called Ur-Hamlet), and King Lear is an adaptation of an earlier play, also called King Lear. For plays on historical subjects, Shakespeare relied heavily on two principal texts. Most of the Roman and Greek plays are based on Plutarch's Parallel Lives (from the 1579 English translation by Sir Thomas North), and the English history plays are indebted to Raphael Holinshed's 1587 edition of The Chronicles of England, Scotland, and Ireland (which provided material for Macbeth and King Lear). Shakespeare also possibly borrowed stylistic elements from contemporary playwrights like Christopher Marlowe. One of Shakespeare's most original plays--at least in terms of writing, themes, and setting--was The Tempest.
Shakespeare's plays tend to be placed into three main stylistic groups:
- early romantic comedies and histories (such as A Midsummer Night's Dream and Henry IV, Part 1)
- middle period romantic comedies and histories (which includes his most famous tragedies, Othello, Macbeth, Hamlet and King Lear, as well as "problem plays" such as Troilus and Cressida)
- later romances (such as The Winter's Tale and The Tempest).
The earlier plays range from broad comedy to historical nostalgia, while the middle-period plays tend to be grander in terms of theme, addressing such issues as betrayal, murder, lust, power, and ambition. By contrast, his late romances feature redemptive plotlines with ambiguous endings and the use of magic and other fantastical elements. However, the borders between these genres are never clear.
About half of Shakespeare's plays first appeared in print as a series of quartos, but the others remained unpublished until 1623 when the posthumous First Folio was published by two actors who had been in Shakespeare's company: John Heminges and Henry Condell (some plays partly by him were published even later). The traditional division of his plays into comedies, histories and tragedies follows the logic of the First Folio. It is at this point that stage directions, punctuation and act divisions enter his plays, setting the trend for further future editorial decisions. Modern criticism has also labelled some of his plays "problem plays" or tragi-comedies, as they elude easy categorisation, or perhaps purposefully break generic conventions. The term "romances" has also been preferred for the later comedies.
There are many controversies about the exact chronology of Shakespeare's plays. In addition, the fact that Shakespeare did not produce an authoritative print version of his plays during his life accounts for part of the textual problem often noted with his plays, which means that for several of the plays there are different textual versions. As a result, the problem of identifying what Shakespeare actually wrote became a major concern for most modern editions. Textual corruptions also stem from printers' errors, compositors' misreadings, or wrongly scanned lines from the source material. Additionally, in an age before standardised spelling, Shakespeare often wrote a word several times in a different spelling, contributing further to the transcribers' confusions. Modern scholars also believe Shakespeare revised his plays throughout the years, sometimes leading to two existing versions of one play.
Shakespeare's sonnets are 154 poems that deal with such themes as love, beauty, and mortality. All but two appeared in the 1609 publication entitled Shakespeare's Sonnets; numbers 138 ("When my love swears that she is made of truth") and 144 ("Two loves have I, of comfort and despair") had been published in a 1599 miscellany entitled The Passionate Pilgrim. The sonnets were written over a number of years, probably beginning in the early 1590s.
The conditions under which the sonnets were published are unclear. The 1609 text is dedicated to one "Mr. W.H.", who is described as "the only begetter" of the poems in the dedication. It is unknown if the dedication was written by Shakespeare or Thomas Thorpe, the publisher. It is also unknown who this man was, although there are many theories, including those who believe him to be the young man featured in the sonnets.  In addition, it is not known whether the publication of the sonnets was even authorised by Shakespeare.
Shakespeare also wrote several longer poems, Venus and Adonis, The Rape of Lucrece and A Lover's Complaint. These poems appear to have been written either in an attempt to win the patronage of a rich benefactor (as was common at the time) or as the result of such patronage. For example, The Rape of Lucrece and Venus and Adonis were both dedicated to Shakespeare's patron, Henry Wriothesley, 3rd Earl of Southampton.
Shakespeare also wrote the short poem The Phoenix and the Turtle. The anthology The Passionate Pilgrim was attributed to him upon its first publication in 1599, but in fact only five of its poems are by Shakespeare and the attribution was withdrawn in the second edition.
Shakespeare's works have been a major influence on subsequent theatre. He transformed English theatre by expanding expectations about what could be accomplished through characterisation, plot, action, language, and genre. His poetic artistry helped raise the status of popular theatre, permitting it to be admired by intellectuals as well as by those seeking pure entertainment.
Theatre was changing when Shakespeare arrived in London in the late 1580s or early 1590s. Previously, the most common forms of popular English theatre were the Tudor morality plays. These plays, which blend piety with farce, were allegories in which the characters are personified moral attributes who validate the virtues of Godly life by prompting the protagonist to choose such a life over evil. The characters and plot situations are symbolic rather than realistic. As a child, Shakespeare would likely have been exposed to this type of play (along with mystery plays and miracle plays). Meanwhile, at the universities, academic plays were being staged based on Roman closet dramas. These plays, often performed in Latin, used a more exact and academically respectable poetic style than the morality plays, but they were also more static, valuing lengthy speeches over physical action.
By the late 16th century, the popularity of morality and academic plays waned, and playwrights like Thomas Kyd and Christopher Marlowe began to revolutionise theatre by blending the old morality drama with academic theatre to produce a new secular form. The new drama had the poetic grandeur and philosophical depth of the academic play and the bawdy populism of the moralities. However, it was more ambiguous and complex in its meanings, and less concerned with simple moral allegories. Shakespeare took these changes further, creating plays that not only resonated on an emotional level with audiences but also explored the basic elements of what it means to be human.
Shakespeare's reputation has grown considerably since his own time. During his lifetime and shortly after his death, Shakespeare was well-regarded but not considered the supreme poet of his age. He was included in some contemporary lists of leading poets, but he lacked the stature of Edmund Spenser or Philip Sidney. After the Interregnum stage ban of 1642–1660, the new Restoration theatre companies had the previous generation of playwrights as the mainstay of their repertory, most of all the phenomenally popular Beaumont and Fletcher team, but also Ben Jonson and Shakespeare. As with other older playwrights, Shakespeare's plays were mercilessly adapted by later dramatists for the Restoration stage with little of the reverence that would later develop.
Beginning in the late 17th century, Shakespeare began to be considered the supreme English-language playwright (and, to a lesser extent, poet). Initially this reputation focused on Shakespeare as a dramatic poet, to be studied on the printed page rather than in the theatre. By the early 19th century, though, Shakespeare had gained fame and popularity. During this time, theatrical productions of Shakespeare provided spectacle and melodrama for the masses and were extremely popular. Romantic critics such as Samuel Taylor Coleridge then raised admiration for Shakespeare to adulation or bardolatry (from bard + idolatry), in line with the Romantic reverence for the poet as prophet and genius. In the middle to late 19th century, Shakespeare also became an emblem of English pride and a "rallying-sign", as Thomas Carlyle wrote in 1841, for the whole British Empire.
His reputation on the European continent struggled until the early 19th century when with the advent of romanticism it suddenly took off, developing almost to idolatry. Particularly influential were the German translations by August Schlegel.
Reverence has provoked a negative reaction. In the 21st century most inhabitants of the English-speaking world encounter Shakespeare at school at a young age, and there is an association by some students of his work with boredom and incomprehension and of "high art" not easily appreciated by popular culture, an ironic fate considering the social mix of Shakespeare's audience. At the same time, Shakespeare's plays remain more frequently staged than the works of any other playwright and are frequently adapted into film—including Hollywood movies specifically marketed to broad teenage audiences, although many simply take credit for his plots rather than his narrative. Famously, Shakespeare's plays are often transferred to a different environment even when retaining his dialogue.
On another level, many modern English words and phrases that are taken for granted were invented by Shakespeare.
In a poll of British librarians asking which book every adult should read before they die, Shakespeare did not appear in the (published) top 30 ().
Speculations about Shakespeare
Over the years such figures as Delia Bacon, Ignatius Donnelly and Mark Twain have expressed disbelief that the man from Stratford-upon-Avon actually produced the works attributed to him. Some of these claims rely on conspiracy theories to explain the lack of direct historical evidence for them, although their advocates also point to evidentiary gaps in the orthodox history. Most professional scholars consider the argument baseless, and attribute the debate to the scarcity and ambiguity of many of the historical records of Shakespeare's life.
Edward de Vere, the 17th Earl of Oxford, an English nobleman and intimate of Queen Elizabeth, became the most prominent alternative candidate for authorship of the Shakespeare canon, after having been identified in the 1920s. Oxford partisans note the similarities between the Earl's life, and events and sentiments depicted in the plays and sonnets. The principal hurdle for the Oxfordian theory is the evidence that many of the Shakespeare plays were written after their candidate's death, but well within the lifespan of William Shakespeare. Christopher Marlowe is considered by some to be the most highly qualified to have written the works of Shakespeare. It has been speculated that Marlowe's recorded death in 1593 was faked for various reasons and that Marlowe went into hiding, subsequently writing under the name of William Shakespeare; this is called the Marlovian theory. Sir Francis Bacon is another proposed author for the Shakespeare works. Besides having travelled to some of the countries in which the plays are set, he could also have read the Shakespeare sources in their original Greek, Italian, Hebrew, or French. He described himself as a "Concealed Poet" and was alive at the time of the publication of the First Folio in 1623. Arguments against Bacon include the suggestion that he had no time to write so many plays, and that his style is different from Shakespeare's.
A question in mainstream academia addresses whether Shakespeare himself wrote every word of his commonly accepted plays, given that collaboration between dramatists routinely occurred in the Elizabethan theatre. Serious academic work continues to attempt to ascertain the authorship of plays and poems of the time, both those attributed to Shakespeare and others.
There is little direct evidence about Shakespeare's sexuality except that he married Anne Hathaway and fathered three children. Circumstantial evidence suggests that Shakespeare's wedding to Hathaway was hurried because she was already pregnant; their first child, Susanna, was born six months after the marriage ceremony on May 26, 1583, and a marriage license was issued for the couple after only one reading of their intent to marry (the reading was normally done three times to give local residents a chance to voice any legal or other objections to the marriage). It is possible that Shakespeare felt trapped by this marriage, speculation supported by a poem Shakespeare wrote where he played off Anne Hathaway's name (writing "Hate away") and by how Shakespeare left his family and moved to London. 
While in London, Shakespeare may have had affairs with different women. One anecdote is provided by John Manningham, a law student who wrote in his diary that Shakespeare had a brief affair with a woman during a performance of Richard III. While this is one of the few surviving contemporary anecdotes about Shakespeare, scholars are not convinced it is true (although the anecdote may have helped inspire the 1998 film Shakespeare in Love). Possible evidence of other affairs are that twenty-six of Shakespeare's Sonnets are love poems addressed to a married woman (the so-called "Dark Lady").
In recent decades, some scholars have suggested that Shakespeare was bisexual. While twenty-six of Shakespeare's Sonnets are addressed to his Dark Lady, one hundred and twenty-six are addressed to a young man (known as the "Fair Lord"). The amorous tone of these focuses on the young man's beauty and the writer's devotion. In 1954, C.S. Lewis wrote that the sonnets are "too lover-like for ordinary male friendship" (although he added that they are not the poetry of "full-blown pederasty") and that he "found no real parallel to such language between friends in the sixteenth-century literature." Nonetheless, others interpret them as referring to intense friendship rather than sexual love.
In 1559, five years before Shakespeare's birth, the Elizabethan Religious Settlement finally severed the Church of England from the Roman Catholic Church after decades of uncertainty. In the ensuing years, extreme pressure was placed on England's Catholics to convert to the Protestant Church of England, and recusancy laws made Catholicism illegal. Some historians maintain that in Shakespeare's lifetime there was a substantial and widespread quiet resistance to the newly imposed faith. Some scholars, using both historical and literary evidence, have argued that Shakespeare was one of these recusants, but this cannot be proven absolutely.
There is evidence that members of Shakespeare's family were recusant Catholics. The strongest evidence is a tract professing secret Catholicism signed by John Shakespeare, father of the poet. The tract was found in the rafters of Shakespeare's birthplace in the eighteenth century, and was seen and described by the reputable scholar Edmond Malone. However, the tract has since been lost, and its authenticity cannot therefore be proven. John Shakespeare was also listed as one who did not attend church services, but this was "for feare of processe for Debtte", according to the commissioners, not because he was a recusant . Then again, avoiding creditors may have merely been a convenient pretext for a recusant's avoidance of the established church's services.
Shakespeare's mother, Mary Arden, was a member of a conspicuous and determinedly Catholic family in Warwickshire . In 1606, William's daughter Susanna was listed as one of the residents of Stratford refusing to take Holy Communion, which may suggest Catholic sympathies. Archdeacon Richard Davies, an eighteenth century Anglican cleric, allegedly wrote of Shakespeare: "He dyed a Papyst". Four of the six schoolmasters at the grammar school during Shakespeare's youth were Catholic sympathisers , and Simon Hunt, likely one of Shakespeare’s teachers, later became a Jesuit .
While none of this evidence proves Shakespeare's own Catholic sympathies, one historian, Clare Asquith, has claimed that those sympathies are detectable in his writing. Asquith claims that Shakespeare uses terms such as "high" when referring to Catholic characters and "low" when referring to Protestants (the terms refer to their altars) and "light" or "fair" to refer to Catholic and "dark" to refer to Protestant, a reference to certain clerical garbs. Asquith also detects in Shakespeare's work the use of a simple code used by the Jesuit underground in England which took the form of a mercantile terminology wherein priests were 'merchants' and souls were 'jewels', the people pursuing them were 'creditors', and the Tyburn gallows where the members of the underground died was called 'the place of much trading'. The Jesuit underground used this code so their correspondences looked like innocuous commercial letters, and Asquith claims that Shakespeare also used this code.
Shakespeare’s Catholicism is by no means universally accepted. The Catholic Encyclopedia questions not only his Catholicism, but whether "Shakespeare was not infected with the atheism, which ... was rampant in the more cultured society of the Elizabethan age." Stephen Greenblatt, of Harvard, suspects Catholic sympathies of some kind or another in Shakespeare and his family but considers the writer to be a less than pious person with essentially worldly motives. An increasing number of scholars do look to matters biographical and evidence from Shakespeare’s work such as the placement of young Hamlet as a student at Wittenberg while old Hamlet’s ghost is in purgatory, the sympathetic view of religious life ("thrice blessed"), scholastic theology in "The Phoenix and the Turtle", and sympathetic allusions to martyred English Jesuit St. Edmund Campion in Twelfth Night and many other matters as suggestive of a Catholic worldview. However, these may have been continuations of old literary conventions rather than determined Catholicism just as the Robin Hood ballads continued to have friars in them after the Reformation.
Furthermore, Shakespeare's plays sometimes criticise Catholicism. The Porter's speech in Macbeth has been read by some as a criticism of the equivocation of Father Henry Garnet after it became topical in 1606 due to his execution.
