War and Peace broadly focuses on Napoleon’s invasion of Russia in 1812 and follows three of the most well-known characters in literature: Pierre Bezukhov, the illegitimate son of a count who is fighting for his inheritance and yearning for spiritual fulfillment; Prince Andrei Bolkonsky, who leaves his family behind to fight in the war against Napoleon; and Natasha Rostov, the beautiful young daughter of a nobleman who intrigues both men.

As Napoleon’s army invades, Tolstoy brilliantly follows characters from diverse backgrounds—peasants and nobility, civilians and soldiers—as they struggle with the problems unique to their era, their history, and their culture. And as the novel progresses, these characters transcend their specificity, becoming some of the most moving—and human—figures in world literature. The work is epic in scale and is regarded as one of the most important works of world literature.

War and Peace is generally thought to be one of the greatest novels ever written, remarkable for its dramatic breadth and unity. Its vast canvas includes 580 characters, many historical with others fictional. The story moves from family life to the headquarters of Napoleon, from the court of Alexander I of Russia to the battlefields of Austerlitz and Borodino. Tolstoy's original idea for the novel was to investigate the causes of the Decembrist revolt, to which it refers only in the last chapters, from which can be deduced that Andrei Bolkonski's son will become one of the Decembrists. The novel explores Tolstoy's theory of history, and in particular the insignificance of individuals such as Napoleon and Alexander.

Somewhat surprisingly, Tolstoy did not consider War and Peace to be a novel (nor did he consider many of the great Russian fictions written at that time to be novels). This view becomes less surprising if one considers that Tolstoy was a novelist of the realist school who considered the novel to be a framework for the examination of social and political issues in nineteenth-century life. War and Peace (which is to Tolstoy really an epic in prose) therefore did not qualify. Tolstoy thought that Anna Karenina was his first true novel.
