Middle English is the period in the history of the English language between the High and Late Middle Ages, or roughly during the four centuries between the late 11th and the late 15th century.

Middle English developed out of Late Old English in Norman England (1066–1154) and was spoken throughout the Plantagenet era (1154–1485). The Middle English period ended at about 1470, when the Chancery Standard, a form of London-based English, began to become widespread, a process aided by the introduction of the printing press to England by William Caxton in the late 1470s. By that time the variant of the Northumbrian dialect (prevalent in Northern England) spoken in southeast Scotland was developing into the Scots language. The language of England as used after 1470 and up to 1650 is known as Early Modern English.

Unlike Old English, which tended largely to adopt Late West Saxon scribal conventions in the period immediately before the Norman conquest of England, written Middle English displays a wide variety of scribal (and presumably dialectal) forms. This diversity suggests the gradual end of the role of Wessex as a focal point and trend-setter for writers and scribes, the emergence of more distinct local scribal styles and written dialects, and a general pattern of transition of activity over the centuries that followed, as Northumbria, East Anglia, and London successively emerged as major centres of literature, each with their own particular interests.

John Skelton, also known as John Shelton (c. 1460 – 21 June 1529), possibly born in Diss, Norfolk, was an English poet.

He is said to have been educated at Oxford. He certainly studied at Cambridge, and he is probably the "one Scheklton" mentioned by William Cole as taking his M.A. degree in 1484. In 1490, William Caxton writes of him, in the preface to The Boke of Eneydos compyled by Vyrgyle, in terms which prove that he had already won a reputation as a scholar. "But I pray mayster John Skelton," he says, "late created poete laureate in the unyversite of Oxenforde, to oversee and correct this sayd booke ... for him I know for suffycyent to expowne and englysshe every dyffyculte that is therin. For he hath late translated the epystlys of Tulle, and the boke of dyodorus siculus, and diverse other works ... in polysshed and ornate termes craftely ... suppose he hath drunken of Elycons well."

The laureateship referred to was a degree in rhetoric. In 1493 Skelton received the same honour at Cambridge, and also, it is said, at Leuven. He found a patron in the pious and learned Countess of Richmond, Henry VII's mother, for whom he wrote Of Mannes Lyfe the Peregrynacioun, a translation, now lost, of Guillaume de Diguileville's Pèlerinage de la vie humaine. An elegy "Of the death of the noble prince Kynge Edwarde the forth," included in some of the editions of the Mirror for Magistrates, and another (1489) on the death of Henry Percy, fourth earl of Northumberland, are among his earliest poems.
