Context paragraphs:
National poet: A national poet or national bard is a poet held by tradition and popular acclaim to represent the identity, beliefs and principles of a particular national culture.  The national poet as culture hero is a long-standing symbol, to be distinguished from successive holders of a bureaucratically-appointed poet-laureate office.  The idea and honoring of national poets emerged primarily during Romanticism, as a figure that helped consolidation of the nation states, as it provided validation of their ethno-linguistic groups.

Robert Burns: Robert Burns (25 January 175921 July 1796), also known as Rabbie Burns, the Bard of Ayrshire, Ploughman Poet and various other names and epithets, was a Scottish poet and lyricist.  He is widely regarded as the national poet of Scotland and is celebrated worldwide.  He is the best known of the poets who have written in the Scots language, although much of his writing is also in English and a light Scots dialect, accessible to an audience beyond Scotland.  He also wrote in standard English, and in these writings his political or civil commentary is often at its bluntest.

He is best known for the satirical plays "Every Man in His Humour" (1598), "Volpone, or The Fox" (c. 1606), "The Alchemist" (1610) and "Bartholomew Fair" (1614) and for his lyric poetry; he is generally regarded as the second most important English playwright during the reign of James I after William Shakespeare.

Shakespeare Jubilee: The Shakespeare Jubilee was staged in Stratford-upon-Avon between 6–8 September 1769.  The jubilee was organised by the actor and theatre manager David Garrick to celebrate the Jubilee of the birth of William Shakespeare, although it was in 1616 when he died.  It had a major impact on the rising tide of bardolatry that led to Shakespeare becoming established as the English national poet.  Thomas Arne composed the song "Soft Flowing Avon" for the Jubilee.

Thomas Jevon: Thomas Jevon (1652–1688) was an English playwright, and one of the first English Harlequins.  He began his career as a dancing master, but worked his way onto the stage, and played leading low-comedy parts in London between 1673 and 1688.  His brother-in-law was the English playwright and poet laureate Thomas Shadwell.

Adam Mickiewicz: Adam Bernard Mickiewicz ( ; 24 December 179826 November 1855) was a Polish poet, dramatist, essayist, publicist, translator, professor of Slavic literature, and political activist.

A principal figure in Polish Romanticism, he is counted as one of Poland's "Three Bards" (""Trzej Wieszcze"") and is widely regarded as Poland's greatest poet.  He is also considered one of the greatest Slavic and European poets and has been dubbed a "Slavic bard".  A leading Romantic dramatist, he has been compared in Poland and Europe to Byron and Goethe.

"Hamlet" was the first British film to win the Academy Award for Best Picture.  It is also the first sound film of the play in English.  A 1935 sound film adaptation, "Khoon Ka Khoon", had been made in India and filmed in the Urdu language.
