William Shakespeare was established in London's theatrical world by 1592, although the details of his first arrival and early employment remain uncertain. He worked as an actor and playwright and published the narrative poems Venus and Adonis and The Rape of Lucrece during the 1590s. From 1594 he belonged to the Lord Chamberlain's Men, becoming a shareholder whose income depended on the company's success as well as on writing individual plays.

The company developed a repertory that included histories, comedies, and tragedies. Shakespeare's early histories explored struggles over English kingship, while comedies such as A Midsummer Night's Dream and The Merchant of Venice combined multiple plots and contrasting social worlds. The Globe opened in 1599, providing a major venue for the company and connecting his career to the commercial organization of public theater. After James I's accession in 1603, royal patronage transformed the company into the King's Men. It later also used the indoor Blackfriars theater.

During his mature career Shakespeare wrote Hamlet, Othello, King Lear, Macbeth, and other tragedies examining power, family, ambition, and moral choice. Exact dates and the order of some plays remain debated, and surviving texts reflect different stages of publication and performance. His sonnets appeared in 1609; attempts to identify their speakers and addressees with particular personal relationships remain speculative. Later plays including The Winter's Tale and The Tempest employed reunion, loss, and reconciliation, and collaboration with other dramatists became important in his final theatrical work.

Shakespeare maintained property and family connections in Stratford-upon-Avon while working in London. Purchase of New Place in 1597 demonstrated his growing prosperity, but the familiar picture of a precisely dated, complete retirement is stronger than the evidence allows. He died in 1616. In 1623 his colleagues John Heminges and Henry Condell helped publish the First Folio, preserving many plays that had not previously appeared in print. Later editors, performers, translators, and theater companies continually reshaped their presentation and reception. His career was rooted in an ensemble and a competitive theatrical business, rather than in solitary literary production alone. The surviving record supports his authorship and professional activity while leaving substantial gaps in personal biography.
