The Defense is the third novel written by Vladimir Nabokov after he had immigrated to Berlin. It was first published in Russian 1930 and later in English in 1964.

Vladimir Vladimirovich Nabokov, also known by the pen name Vladimir Sirin, was an expatriate Russian and Russian-American novelist, poet, translator, and entomologist. Born in Imperial Russia in 1899, Nabokov wrote his first nine novels in Russian (1926–1938) while living in Berlin, where he met his wife. He achieved international acclaim and prominence after moving to the United States, where he began writing in English. Nabokov became an American citizen in 1945 and lived mostly on the East Coast before returning to Europe in 1961, where he settled in Montreux, Switzerland.
