The publisher's special commentary chapter and the author's biography are included in this version. Leo Tolstoy’s War and Peace was first published in 1869. This is one of the most important works of world literature, being considered Tolstoy's finest literary achievement. Leo Tolstoy’s War and Peace delineates in graphic detail events surrounding the French invasion of Russia, and the impact of the Napoleonic era on Tsarist society, as seen through the eyes of five Russian aristocratic families. The author himself, a little enigmatically, addressed of War and Peace that it was ""not a novel, even less is it a poem, and still less an historical chronicle."" Large sections of the work, especially in the later chapters, are philosophical discussion rather than narrative.
