Modern Greek literature refers to literature written in common Modern Greek, emerging from late Byzantine times in the 11th century AD. During this period, spoken Greek became more prevalent in the written tradition, as demotic Greek came to be used more and more over the Attic idiom and the katharevousa reforms.
Modern Greek literature is usually (but not exclusively) written in polytonic orthography, though the monotonic orthography was made official in 1981. Modern Greek literature is represented by many important and internationally knwon writers, poets and novelists such as Nikos Kazantzakis, George Seferis, Odysseas Elytis, Constantine Cavafy and others. George Seferis and Odysseas Elytis have been awarded the Nobel Prize in Literature.
