Prince Peter Alexeyevich Kropotkin (December 9, 1842 - February 8, 1921) lived in Brighton from 1911 to 1917. He was a Russian figure, writer, revolutionary, scientist, economist, sociologist, historian, essayist, researcher, political scientist, biologist, geographer, and philosopher who actively promoted the ideas of anarcho-communism.

Kropotkin was born into an aristocratic landowning family and received his education at a military academy. After that, he served as an officer in Siberia and participated in several geological expeditions. In 1874, he was arrested for revolutionary activities, but two years later he managed to escape. For the next 41 years, he was in exile in Switzerland, France (where he spent nearly four years in prison), and England. During this time, Kropotkin actively lectured and published works on anarchism and geography. After the 1917 revolution, he returned to Russia but remained disillusioned with the Bolshevik regime.

Kropotkin advocated for the creation of a decentralized communist society, free from central authority, based on voluntary associations of self-governing communities and workers' enterprises. He wrote numerous books, pamphlets, and articles, among which the most famous are "Bread and Freedom" and "Fields, Factories, and Workshops." His main scientific work, "Mutual Aid as a Factor of Evolution," was also published. He contributed an article on anarchism to the eleventh edition of the Encyclopaedia Britannica and left unfinished work on anarchist ethical philosophy.
