This article presents lists of the literary events and publications in the 12th century. The 12th century in Western Europe saw an increase in the production of Latin texts and a proliferation of literate clerics from the multiplying cathedral schools. At the same time, vernacular literatures ranging from Provençal to Icelandic embodied in lyric and romance the values and worldview of an increasingly self-conscious and prosperous courtly aristocracy. These two trends contributed to a sweeping revival of letters with a lasting influence on the development of literature in the following centuries.
