Which Leo Tolstoy novel is set partly in the Caucasus and follows Olenin?

The Leo Tolstoy novel set partly in the Caucasus and centered on Olenin is The Cossacks.

Tolstoy began The Cossacks during the 1850s, drawing on his experiences in the Caucasus and his service in the Russian army. The novel was published in 1863. Its protagonist, Dmitri Olenin, leaves urban society and travels to a Cossack settlement, where he becomes fascinated by rural life and by Maryanka.

The book contrasts aristocratic Russian society with the traditions, violence, freedom, and communal life of the Terek Cossacks. Olenin’s romantic and philosophical hopes gradually collide with the realities of the community he idealizes.

The Cossacks is sometimes confused with Hadji Murat, another Tolstoy work set in the Caucasus. Hadji Murat focuses on a historical Avar leader, whereas The Cossacks is a coming-of-age and cultural encounter novel.
