In 1902 Tolstoy wrote a letter to the Tsar, calling for social justice, to prevent a civil war, and in 1904, during the Russo-Japanese War, Tolstoy wrote a condemnation of war. The Tsar replied by increasing police surveillance on Tolstoy. In November of 1910 he left his estate, probably taking the path of a wandering ascetic, which he had been pursuing for decades. He left home without explanations and took a train, in which he caught pneumonia, and died at a remote station of Astapovo. He was laid to rest in his estate of Yasnaya Polyana, which was made a Tolstoy National Museum.
His youngest daughter, named Alexandra Tolstoy, was the director of the Tolstoy Museum, and was arrested by the Communists five times. She emigrated from Russia to the United States, where she founded the Tolstoy Foundation. She helped many prominent Russian intellectuals, such as Vladimir Nabokov and Sergei Rachmaninoff among many others.
