Anna Karenina is a literary masterpiece written by Russian master-writer Leo Tolstoy. It first appeared in instalments from 1873 to 1877 in the magazine The Russian Messenger. However, due to political disagreements between the magazine editors and Tolstoy, the complete Anna Karenina did not appear until 1878 in novel form. Critics and readers alike regard it as one of the finest novels ever written. It is a work so refined and perfected that another Russian master-writer, Fyodor Dostoyevsky, called it a flawless work of art.
