William Shakespeare was born in Stratford-upon-Avon, Warwickshire, in 1564. The date of his birth is not known but is traditionally 23 April, St George's Day. Aged 18, he married a Stratford farmer's daughter, Anne Hathaway. They had three children. Around 1585 William joined an acting troupe on tour in Stratford from London, and thereafter spent much of his life in the capital. Julius Caesar, one of four plays Shakespeare set in ancient Rome, was probably written in 1599 and also first performed in that year. A member of the leading theatre group in London, the Chamberlain's Men, which built the Globe Theatre and frequently performed in front of Queen Elizabeth I, Shakespeare wrote 36 plays and much poetry besides. He died in 1616.
