Fyodor Mikhailovich Dostoevsky was a Russian novelist, short story writer, essayist, and journalist. His literary works explore human psychology in the troubled political, social, and spiritual atmospheres of 19th-century Russia, and engage with a variety of philosophical and religious themes. His most acclaimed novels include Crime and Punishment (1866), The Idiot (1869), Demons (1872), and The Brothers Karamazov (1880). Many literary critics rate him as one of the greatest novelists in all of world literature, as multiple of his works are considered highly influential masterpieces. His 1864 novella Notes from Underground is considered to be one of the first works of existentialist literature. As such, he is also looked upon as a philosopher and theologian as well.

Lev Nikolayevich Tolstoy (Russian: Лев Николаевич Толстой; most appropriately used Liev Tolstoy; commonly Leo Tolstoy in Anglophone countries) was a Russian writer who primarily wrote novels and short stories. Later in life, he also wrote plays and essays. His two most famous works, the novels War and Peace and Anna Karenina, are acknowledged as two of the greatest novels of all time and a pinnacle of realist fiction. Many consider Tolstoy to have been one of the world's greatest novelists. Tolstoy is equally known for his complicated and paradoxical persona and for his extreme moralistic and ascetic views, which he adopted after a moral crisis and spiritual awakening in the 1870s, after which he also became noted as a moral thinker and social reformer. His literal interpretation of the ethical teachings of Jesus, centering on the Sermon on the Mount, caused him in later life to become a fervent Christian anarchist and anarcho-pacifist. His ideas on nonviolent resistance, expressed in such works as The Kingdom of God Is Within You, were to have a profound impact on such pivotal twentieth-century figures as Mohandas Gandhi and Martin Luther King, Jr.
