King Richard the Second is a history play by William Shakespeare believed to have been written in approximately 1595. It is based on the life of King Richard II of England (ruled 1377–1399) and is the first part of a tetralogy, referred to by some scholars as the Henriad, followed by three plays concerning Richard's successors: Henry IV, Part 1; Henry IV, Part 2; and Henry V. It may not have been written as a stand-alone work. 

The play spans only the last two years of Richard's life, from 1398 to 1400.

Although the First Folio (1623) edition of Shakespeare's works lists the play as a history play, the earlier Quarto edition of 1597 calls it The tragedie of King Richard the second. 

William Shakespeare (1564-1616) was an English poet, playwright and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. His extant works, including some collaborations, consist of about 38 plays, 154 sonnets, two long narrative poems, and a few other verses. His plays have been translated into every major living language and are performed more often than those of any other playwright.

Shakespeare was a respected poet and playwright in his own day, but his reputation did not rise to its present heights until the 19th century. His plays remain highly popular today and are constantly studied, performed, and reinterpreted in diverse cultural and political contexts throughout the world.

In 2016, celebrations will commence in the United Kingdom and across the world to honour The Bard's 400th anniversary.
