INTRODUCTION to Origin of the Family, Private Property and the State, by Frederick Engels by Eleanor Burke Leacock IN THE Origin of the Family, Private Property and the State, Engels outlines the successive social and economic forms which underlay the broad sweep of early human history, as mankind gained increasing mastery over the sources of subsistence. The book was written after Marx’s death, but was drawn from Marx’s as well as Engels’ own notes. It was based on the work, Ancient Society, which appeared in 1877 and was written by the anthropologist Lewis Henry Morgan, who, as Engels wrote in 1884, “in his own way. . . discovered afresh in America the materialistic conception of history discovered by Marx 40 years ago.” The contribution Marx and Engels made to Morgan’s work was to sharpen its theoretical implications, particularly with regard to the emergence of classes and the state. Although Engels’ book was written well before most of the now available material on primitive and early urban society had been amassed, the fundamentals of his outline for history have remained valid. Moreover, many issues raised by Morgan’s and then Engels’ work are still the subjects of lively debate among anthropologists, while the theoretical implications of these issues are still matters of concern to Marxist scholars generally. Morgan described the evolution of society in some 560 pages.
