War and Peace is a novel by the Russian author Leo Tolstoy. It is regarded as one of the central works of world literature. War and Peace and Tolstoy’s other major prose work, Anna Karenina (1875–77), are considered Tolstoy’s finest literary achievements. The novel charts the history of the French invasion of Russia, and the impact of the Napoleonic era on Tsarist society, through the stories of five Russian aristocratic families. Portions of an earlier version, titled The Year 1805, were serialized in The Russian Messenger between 1865 and 1867. The novel was first published in its entirety in 1869. Newsweek in 2009 ranked it first in its Top 100 Books. In 2007, Time magazine ranked War and Peace third in its poll of the 10 greatest books of all time while Anna Karenina was ranked first.
