Middle English literature

Early period
After the Norman conquest of England, the written form of the Anglo-Saxon language continued in some monasteries but few literary works are known from this period. Under the influence of the new aristocracy, Law French became the standard language of courts, parliament, and polite society.
As the invaders integrated, their language and literature mingled with that of the natives. The Norman dialects of the ruling classes became Anglo-Norman, and Anglo-Saxon underwent a gradual transition into Middle English. Political power was no longer in English hands, so the West Saxon literary language had no more influence than any other dialect. Middle English literature is written, then, in the many dialects that correspond to the history, culture, and background of the individual writers.
While Anglo-Norman or Latin was preferred for high culture and administration, English literature by no means died out, and a number of important works illustrate the development of the language. Around the turn of the thirteenth century, Layamon wrote his Brut, based on Wace's twelfth century Anglo-Norman epic of the same name. Layamon's language is recognisably Middle English, though his prosody shows a strong Anglo-Saxon influence remaining.
Other transitional works were preserved as popular entertainment, including a variety of romances and lyrics. With time, the English language regained prestige, and in 1362 it replaced French and Latin in Parliament and courts of law. Early examples of Middle English literature are the Ormulum, Havelock the Dane, and Thomas of Hales's Love Rune.
The Mercian dialect thrived between the 8th and 13th centuries and was referred to by John Trevisa, writing in 1387:
"For men of the est with men of the west, as it were undir the same partie of hevene, acordeth more in sownynge of speche than men of the north with men of the south, therefore it is that Mercii, that beeth men of myddel Engelond, as it were parteners of the endes, understondeth better the side langages, northerne and southerne, than northerne and southerne understondeth either other…"
Not much lyrical poetry of the thirteenth century remains, and even fewer secular love poems; "Foweles in the frith" is one exception.
