All 38 plays which we recognize as Shakespeare's were published before 1634 in some form. We are very fortunate in that two friends of Shakespeare's, Heminges and Condell, decided after his death to publish a compendium of his plays.
Between about 1590 and 1613, Shakespeare wrote at least 37 plays and collaborated on several more. Many of these plays were very successful both at court and in the public playhouses. In 1613, Shakespeare retired from the theatre and returned to Stratford-upon-Avon.
