War and Peace is a literary work by Russian author Leo Tolstoy. Set during the Napoleonic Wars, the work mixes fictional narrative with chapters discussing history and philosophy. An early version was published serially beginning in 1865, after which the entire book was rewritten and published in 1869. It is regarded, with Anna Karenina, as Tolstoy's finest literary achievement and remains an internationally praised classic of world literature.

Russian is an East Slavic language, spoken primarily in Russia. It is the native language of the Russians and belongs to the Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages. It was the de facto and de jure official language of the former Soviet Union. Russian has remained an official language in independent Russia, Belarus, Kazakhstan, Kyrgyzstan, and Tajikistan, and is still commonly used as a lingua franca in Ukraine, Moldova, the Caucasus, Central Asia, and to a lesser extent in the Baltic states and Israel.
