When was Romeo and Juliet first published?

The first quarto edition of Romeo and Juliet was published in 1597, and is known as the "bad quarto". It is believed that this edition was based on a shortened and pirated version of the play, and contains many errors and omissions. The second quarto edition, published in 1599, is considered to be the more authoritative version, and is the one that is most commonly used in modern productions.
