"Who Killed Cock Robin" is an English nursery rhyme, first appearing in print in the children’s nursery rhyme book ‘Tommy Thumb's Pretty Song Book’, published in 1744, by the London-based publisher, and bookseller Mary Cooper (d. August 5, 1761). Cooper was one of the first publishers of children’s books in English between 1743 and 1761. The song potentially is much older however than 1744; a dead robin is shown killed by an arrow in a 15th century stained glass window at Buckland Rectory in England, and also the rhyme shows similarities to ‘Phyllyp Sparowe’, written in 1508 by the English poet John Skelton (c. 1463 – 21 June 1529). Its association in the early 18th century has been claimed to chronicle the fall of the government ("Robinocracy,") of the first British Prime Minister Robert Walpole (26 August 1676 – 18 March 1745).
