The Russian Marxist and revolutionary Georgi Plekhanov, who is considered to be the founder of the Social-Democratic movement in Russia, was born in 1856 in the village of Gudalovka in what is now the Lipetsk Region. The house which was once owned by the parents of Plekhanov has since been turned into a museum dedicated to him. It details both his personal life and the Social-Democratic movement in Russia, including information on Plekhanov's disagreements with Lenin. There is also a statue of Georgi Plekhanov located next to the museum.
