The Middle Ages lasted from around 500-1500 AD following the fall of Rome. Society was organized around feudalism and the Catholic Church was the main unifying institution. Literature was preserved by monks and courtly traditions like chivalry and courtly love evolved, though these ideals often differed from knights' real lives. After the Norman Conquest in 1066, English culture blended with French influences through borrowed words and legends. Sir Thomas Malory wrote Le Morte d'Arthur in prison, compiling the most popular version of the Arthurian legends. Geoffrey Chaucer was a renowned poet who wrote The Canterbury Tales, capturing a cross-section of medieval English life.
