Astolphe-Louis-Léonor, Marquis de Custine was a French aristocrat and writer who is best known for his travel writing, in particular his account of his visit to Russia, La Russie en 1839. This work documents not only Custine's travels through the Russian Empire, but also the social fabric, economy and way of life during the reign of Nicholas I.

Nicholas I was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland. He was the third son of Paul I and younger brother of his predecessor, Alexander I. Nicholas's reign began with the failed Decembrist revolt. He is mainly remembered in history as a reactionary whose controversial reign was marked by geographical expansion, centralisation of administrative policies, and repression of dissent. Nicholas had a happy marriage that produced a large family; all of their seven children survived childhood.
