War and Peace, a Russian novel by Leo Tolstoy, is considered one of the greatest works of fiction. It is regarded, along with Anna Karenina (1873–1877), as Leo Tolstoy's finest literary achievement. Epic in scale, War and Peace delineates in graphic detail events leading up to Napoleon's invasion of Russia, and the impact of the Napoleonic era on Tsarist society, as seen through the eyes of five Russian aristocratic families. Portions of an earlier version having been serialized in the magazine The Russian Messenger between 1865 and 1867, the novel was first published in its entirety in 1869. Newsweek in 2009 ranked it top of its list of Top 100 Books. Leo Tolstoy himself, somewhat enigmatically, said of War and Peace that it was "not a novel, even less is it a poem, and still less an historical chronicle."
